Every feature explained

The fixed order in which StudioSound Pro processes your voice.

Your voice always passes through the same chain of processing steps. The order is chosen so the steps help each other – for example, noise is removed before the compressor makes your voice louder.

• Input gain
• High-pass
• Hum filter
• Noise suppression
• Microphone activation (gate/expander)
• Auto level
• Equalizer
• De-esser
• Compressor
• Studio enhancer
• Output
• Limiter (clipping protection)

The “Signal chain” page shows every block with its current value. Clicking a block bypasses it or turns it back on. The orange bar shows how much the block is working right now.

Tip If something sounds odd, switch blocks off one by one – you will quickly find the step that causes it.

Controls how many pages and controls the app shows.

The mode does not change the sound – only how much you see.

• Simple: dashboard, microphone, auto-calibration, recording, presets, virtual microphone, settings and account. Ideal if you just want to sound good.
• Advanced: adds equalizer, compressor & dynamics and noise & tone – every effect adjustable on its own.
• Studio: also adds the signal chain with all blocks at a glance.

If a link takes you to a hidden page, the app switches to Advanced mode automatically.

The dashboard shows everything important at a glance:

• Voice orb: the glowing sphere moves with your voice. Above it you see whether you are live (green), muted (yellow) or whether the virtual microphone is not connected.
• Start auto-calibration and choose a preset.
• Quick picks: your presets as tiles – one click changes the sound.
• Levels & spectrum: input, output and how hard gate, de-esser, compressor and limiter are working.
• Status tiles: microphone, virtual microphone, latency, audio load, preset, noise floor, voice activity, dropouts.
• Microphone activation & noise suppression right there, the smart sound controls and diagnostics.

The live bar is visible on every page – similar to the player bar in a music app.

• Left: your microphone and the active preset. Clicking opens “Microphone & devices”.
• Large round button: mute the microphone (red = muted).
• Headphone button: monitoring on/off.
• Centre: the level history of the last seconds – you see right away whether your voice is getting through.
• Right: connection status with latency. Green = all good, yellow = notice, red = problem. Clicking opens the matching page.

The unit for loudness differences; dBFS measures level up to the digital maximum.

Decibels are logarithmic: +6 dB roughly doubles the signal level, +10 dB is perceived as about twice as loud. On controls, 0 dB means “unchanged”, positive values boost, negative values cut.

dBFS (full scale) is the scale of the level meters: 0 dBFS is the absolute digital maximum. Anything above is cut off and distorts. Speech is typically between −30 and −10 dBFS, silence below −60 dBFS.

ClippingLevel meter (input & output)

How low or high a sound is – from 20 Hz (low) to 20 kHz (high).

Frequency is how many times a vibration happens per second. Important for voice:

• below 80 Hz: rumble, footsteps, pops – usually unwanted
• 100–250 Hz: body and warmth, too much sounds boomy
• 250–500 Hz: “mud” – too much sounds dull and boxy
• 2–5 kHz: presence and intelligibility
• 5–9 kHz: sibilance (S, SH, Z)
• from 10 kHz: brilliance and “air”

The delay between speaking and the sound arriving in Discord, OBS & co.

Every processing step needs a few milliseconds. StudioSound Pro measures the actual delay from the microphone to the virtual microphone and shows it on the dashboard and in the live bar.

• Up to about 30 ms nobody notices – not even in games or video calls.
• 30–60 ms is fine for conversations and streams.
• AI noise suppression costs about 20 ms (“Strong” about 31 ms), the classic one about 11 ms.
• The audio buffer (settings) decides the rest: smaller buffers = less latency but more risk of dropouts.

Your voice is processed only on your PC – nothing goes to a cloud.

All voice processing, including AI noise suppression, runs in real time on your computer. The microphone signal and recordings are never uploaded. Diagnostic logs contain no speech content.

Only sign-in, licence checks, updates and – if you switch it on – the encrypted cloud backup of your settings use the internet.

Selects the recording device whose voice gets processed.

Choose your real microphone, headset or audio interface here – not “CABLE Output”, which is the virtual microphone StudioSound Pro writes into. Internally everything runs in 32-bit floating point, mono.

“Search devices again” refreshes the list, e.g. after plugging in a USB microphone. If the device disconnects, StudioSound Pro reconnects automatically as soon as it is back.

Tip Below the device you see format, bit depth and buffer – handy when support asks.

Channel (mix both, left, right)Digital gain (input gain)Virtual microphone

Chooses which input channel of your device is used.

Many audio interfaces have two inputs. If your microphone is only in input 1, the right channel contains only noise – then choose “Left channel only (input 1)”. “Mix both channels” is right for normal USB microphones and headsets.

Choose microphone

Makes the microphone signal digitally louder or quieter before processing.

Gain adjusts the input level so the following effects work properly. It is digital – it does not replace the hardware gain on your microphone or interface. If the signal already clips at the device, less gain will not help: turn it down on the device.

Hardware gain (gain knob) and phantom power (48 V) are set directly on the microphone or audio interface.

Tip Aim: when speaking normally the meter peaks around −18 to −10 dBFS. Auto-calibration sets this for you.

Hear your voice in real time on headphones – original or processed.

Monitoring lets you check how you sound while speaking.

• Device: choose your headphones.
• “Hear processed voice”: on = how others hear you; off = the unprocessed original.
• Volume control for monitoring.

Over speakers there is a risk of feedback (howling/echo) because the microphone picks the speakers up again. Diagnostics will warn you.

Before/after comparison (A/B)

Measures microphone and room in about 30 seconds and sets everything up to match.

Calibration listens to your microphone and room and tunes the whole chain – level, high-pass, hum filter, noise suppression, gate threshold, equalizer, de-esser, compressor and output.

How it works:

• Stay silent for 5 seconds: measures noise, hum and clicks in the room.
• Read a short text normally: measures the character, bandwidth and loudness of your voice.
• Speak louder for 5 seconds: checks whether anything clips.

Then you see the result with before/after and can apply it, fine-tune it or save it as a profile.

Tip Speak the way you do in Discord or on stream – at your usual distance from the microphone. Recalibrate after moving the microphone or in a new room.

One-click tweaks to the result: more natural, warmer, stronger, clearer, more bass, less background.

If you almost like the result, use the buttons below the analysis:

• Keep it natural: fewer harmonics and saturation, gentler compression.
• Make warmer: more body, slightly less treble, light saturation.
• Make stronger: more density and presence.
• Make clearer: less mud, more brilliance.
• More bass: more lows, high-pass lower.
• Less background noise: stronger noise suppression and microphone activation.

Every click is heard right away in the before/after comparison. “Apply” makes it live, “Save profile” stores it as a preset.

Auto-calibrationPresets

Shows how your microphone sounds, where calibration aims and what comes out.

The “tone balance” chart shows three curves over frequency: your microphone before, the studio target and the result after. If “after” is close to the target, the voice is balanced.

Next to it, bars compare measured values – for example background in speech pauses and noise while you speak. Shorter is better. Below that you find the detected problems (e.g. hum, quiet microphone) and which values were set.

“A: Before”, “B: After” and “A/B alternating” (switches every 3 seconds) play your calibration recording – at the same loudness so you only compare the tone.

Removes keyboard, fans, hiss and background in real time – locally, no cloud.

Noise suppression separates your voice from noise. There are four levels:

• Off: no processing, no extra latency.
• Light: removes noise, keeps some room sound – the most natural.
• Balanced: removes keyboard, fans and background; pauses without speech are lowered by an extra 30 dB. The best choice for most people.
• Strong: maximum suppression (AI + classic filter), pauses fully silent. Can soften very quiet syllables and breaths.

The “Reduction” bar on the right shows how much is being removed right now.

Tip Better one level lower plus microphone activation – it sounds more natural than “Strong”.

In the app

“Noise & tone” page, selector on the dashboard, smart control “Noise red.”

AI (RNNoise) or classic (DSP)Microphone activation / noise gateLatency

Two noise suppression methods: AI for keyboard & voices, classic for steady noise.

• AI (RNNoise): a neural network recognises what is speech and what is not. Much better against keyboard, mouse clicks, voices and background sounds. Extra latency about 20 ms (Strong: about 31 ms). Works at 48 kHz – at other sample rates the app automatically uses the classic method.
• Classic (DSP): a spectral filter that learns the constant background noise and subtracts it. Very good against fans, hiss and air conditioning, less so against clicks. Lower latency (about 11 ms). At “Strong” (down to −42 dB) the voice can sound slightly “watery”.

RNNoise comes from Xiph.Org and is available under an open BSD licence.

In the app

“Noise & tone” page → Noise suppression → Method

See also

Noise suppressionSample rate (Hz)

Removes electrical hum (50 Hz or 60 Hz) and its harmonics.

Hum often comes from ground loops, unshielded cables or nearby power supplies. The filter cuts the mains frequency and its multiples (harmonics) very narrowly without changing the voice.

• Mains frequency: 50 Hz in Europe, 60 Hz in North America.
• Harmonics: how many multiples (100, 150, 200 Hz …) are removed as well.

Auto-calibration detects hum and switches the filter on if needed.

In the app

“Noise & tone” page → Hum filter

See also

High-pass (rumble filter)Auto-calibration

Removes everything below the voice: rumble, footsteps, pops.

A high-pass lets high frequencies through and fades out low ones. Below about 70–100 Hz speech contains practically nothing useful – but table knocks, footsteps, fan rumble and plosive pops.

• Frequency: cutting starts here. Higher = leaner, lower = fuller.
• Slope: 12 dB/octave (gentle) or 24 dB/octave (steep).

Tip Deep voices: around 60–80 Hz. Bright voices: 90–120 Hz. The smart “Bass” control moves the high-pass too.

Frequency (Hz, kHz)Parametric equalizer

How loud your surroundings are when you are not speaking.

The noise floor is the level in your speech pauses – fans, room, electronics. Measured in dBFS:

• below −55 dBFS (green): very quiet
• −55 to −45 dBFS (yellow): audible, noise suppression helps
• above −45 dBFS (red): loud – use stronger noise suppression or reduce noise sources

If the room is much louder than at the last calibration, diagnostics recommends recalibrating.

Keeps the microphone closed in pauses so keyboard and room don’t get through.

The gate only opens when your voice is loud enough and closes shortly after the last word. Two modes:

• Voice activation (hard): below the threshold the mic is completely silent – like Discord’s voice activity, only more precise. Short clicks don’t open it thanks to the click filter.
• Soft expander: pauses are only made quieter instead of silent. Sounds more natural, quiet words are not lost.

On the dashboard you set the threshold right on the bar: the bar is your current level, the white handle is the threshold. Green = mic open, grey = closed.

Tip Drag the handle just above the level your keyboard and background reach – but below your normal speaking level.

In the app

“Compressor & dynamics” page → Microphone activation, dashboard → Microphone activation

ThresholdClick filterHoldRange (depth)

The level at which an effect kicks in – for the gate: where the microphone opens.

The threshold is the limit in dB. For the gate, the microphone opens as soon as your level is above it. For the compressor and de-esser, reduction only starts above the threshold.

The higher (closer to 0 dB) the threshold, the louder you need to be for the effect to react.

In the app

Microphone activation, de-esser, compressor

Microphone activation / noise gateCompressorDe-esser

How much the gate lowers pauses – from 60 dB it is practically silent.

Range sets by how many dB the signal gets quieter while the gate is closed. 10–20 dB just pulls the background back, from 60 dB it is completely silent.

In the app

“Compressor & dynamics” page → Microphone activation

See also

Microphone activation / noise gate

How long the microphone stays open after the last word.

Hold stops the gate from closing between words or during short breaths and cutting off word endings. Too short: words sound choppy. Too long: keyboard is still audible briefly after the sentence.

In the app

“Compressor & dynamics” page → Microphone activation

See also

Microphone activation / noise gateRelease

Short sounds like key and mouse clicks don’t open the microphone.

The level must stay above the threshold at least this long before the gate opens. A keystroke lasts only a few milliseconds, a word much longer – so clicks are ignored.

In the app

“Compressor & dynamics” page → Microphone activation

See also

LookaheadMicrophone activation / noise gate

Delays the signal slightly so word beginnings aren’t cut despite the click filter.

Because the click filter makes the gate open a little later, the first sound of a word would be missing. Lookahead looks a few milliseconds ahead and opens in time. It costs exactly as much latency as set. The limiter has its own lookahead too.

In the app

“Compressor & dynamics” page → Microphone activation and limiter

See also

Click filterLatencyLimiter / clipping protection

Gap between opening and closing the gate – prevents chattering.

With hysteresis the gate only closes once the level drops a few dB below the opening threshold. Without it the gate would keep opening and closing (“chattering”) at levels right at the threshold.

ThresholdMicrophone activation / noise gate

How much the soft expander makes quiet parts even quieter.

In “soft expander” mode everything below the threshold is lowered by the set ratio: at 2:1, 10 dB below the threshold becomes 20 dB. Higher = more obvious, lower = gentler.

In the app

“Compressor & dynamics” page → Microphone activation (“soft expander” mode)

See also

Microphone activation / noise gateRatio

Evens out loudness changes and makes the voice denser and more present.

The compressor lowers loud parts as soon as they exceed the threshold. Then everything is lifted again (makeup). Result: quiet and loud passages are closer together – the voice sounds professional and doesn’t get lost in game or stream audio.

• Threshold: compression starts here.
• Ratio: how strongly.
• Attack/release: how fast it grabs and lets go.
• Knee: how soft the transition is.
• Makeup: loudness compensation (or automatic).
• Character: different ways of working.

The curve on the right shows input versus output, the dot your current level.

Tip For speech: ratio 2:1 to 4:1 and 3–8 dB of reduction. More quickly sounds squashed.

ThresholdRatioAttackReleaseKneeMakeup gainCompressor characterGain reduction

How strongly the compressor lowers loud parts.

At 3:1 a level 9 dB above the threshold is reduced to 3 dB above it. 1:1 = no compression; from about 10:1 the compressor behaves like a limiter.

In the app

“Compressor & dynamics” page → Compressor

See also

CompressorRatio (expander)

How fast an effect reacts when the level rises.

Short attack (below 5 ms) also catches fast peaks but can soften consonants. Longer attack lets the start of a word through and sounds livelier. For the gate, attack sets how fast it opens.

In the app

Compressor, microphone activation

See also

ReleaseCompressor

How fast an effect lets go when the level drops.

Too short: the compressor “pumps”, the gate chatters. Too long: after loud parts the voice stays too quiet for a moment. 80–200 ms is a good range for speech.

In the app

Compressor, microphone activation, limiter

AttackHoldCompressor

How softly the compressor starts working around the threshold.

At 0 dB (hard knee) compression starts abruptly exactly at the threshold. A soft knee (6–12 dB) fades it in gradually – less noticeable and usually nicer for speech.

In the app

“Compressor & dynamics” page → Compressor

Compressor

Brings the voice back to the right loudness after compression.

Compression makes loud parts quieter – so the voice gets quieter overall. Makeup compensates for that. With “Automatic” the app calculates the compensation from threshold and ratio itself.

In the app

CompressorOutput (output volume)

Six ways of working: from transparent to vintage.

• Transparent: as inaudible as possible, pure loudness control.
• Broadcast: dense and even like radio, with a hint of colour.
• Vocal: tuned for speech, reacts to peaks – the default.
• Fast (FET style): very fast attack, grabs hard, clear colouring – cuts through.
• Smooth (opto style): slower, program-dependent control, very musical and gentle.
• Vintage character: warm, analogue-sounding colour.

In the app

“Compressor & dynamics” page → Compressor → Character

Compressor

Tames harsh S, SH and hissing sounds, only when they get too loud.

Sibilance sits roughly between 5 and 9 kHz and often becomes harsh through compression and presence. The de-esser lowers it precisely – only at the moment it occurs.

• Frequency: where your sibilance is.
• Threshold: from which level it acts.
• Intensity: maximum reduction.
• Split-band mode: lowers only the sibilance range (more natural).
• Wideband mode: briefly lowers the whole voice (stronger).

Slowly adjusts your speaking level – only while you speak.

Auto level keeps your voice at a target level over longer periods, for example when you lean back or get quieter. It adjusts gently and only during speech – pauses are not pulled up, nothing “pumps”.

• Target level: how loud the voice should be on average.
• Max. correction: the most it raises or lowers.

Tip Handy for podcasts and long streams. Off by default; the “Podcast Professional” preset turns it on.

CompressorDigital gain (input gain)

Prevents clipping before it happens – should always be on.

The limiter is the last step in the signal chain. It looks slightly ahead (lookahead) and never lets the level go above the ceiling. So nothing distorts, even if you suddenly laugh or shout.

• Ceiling: the maximum output level in dBFS.
• Release: how fast it lets go after a peak.
• Lookahead: how far it looks ahead.

In the app

“Compressor & dynamics” page → Limiter

ClippingOutput (output volume)Lookahead

How loud your processed voice arrives at the virtual microphone.

Output sets the overall loudness at the end of the chain – for example if others hear you too quietly in Discord. The limiter after it still protects against clipping. Easiest via the smart “Output” control.

Shapes the tone: 10 bands, each with frequency, gain, quality (Q) and filter type.

The equalizer boosts or cuts individual frequency ranges. The curve shows the result, behind it the live spectrum of your voice.

• Drag a point: left/right = frequency, up/down = gain.
• Mouse wheel over a point: bandwidth (Q).
• Double-click: band on/off.
• Right-click: choose filter type.
• Undo, redo and “Reset EQ” below.

In the “Band” area you set the selected band precisely with controls.

Tip Cut first, then boost: taking a little mud out at 250–400 Hz often works better than adding treble.

Filter typesQ (quality, bandwidth)Frequency (Hz, kHz)Spectrum (analyser)High-pass (rumble filter)

The shape of an EQ band: bell, shelf, high-pass, low-pass, band-pass or notch.

• Bell: boosts or cuts a range around the frequency – the default.
• Low shelf: changes everything below the frequency evenly (bass).
• High shelf: changes everything above the frequency (treble, air).
• High-pass: fades out everything below.
• Low-pass: fades out everything above.
• Band-pass: only lets one range through (telephone effect).
• Notch: cuts out a single frequency very narrowly, e.g. a whistle.

Polishes the voice: presence, warmth, bass, brilliance, harmonics and saturation.

The enhancer is a quick “tone shortcut” with six controls – most effective when used sparingly.

• Presence (around 4 kHz): intelligibility and cut.
• Warmth (around 220 Hz): body and fullness.
• Bass (shelf around 110 Hz): depth and volume.
• Brilliance (shelf around 11 kHz): sheen and air.
• Exciter: creates fine harmonics for more detail.
• Saturation: gentle, analogue-sounding density.
• Saturation type: tube (warm, a little more body) or tape (soft, round).

Eight simple controls that drive several effects at once in the background.

Instead of dozens of technical controls, eight controls from 0 to 100 set everything important. 50 is neutral, double-click resets to 50. The controls work on top of the selected preset.

• Warmth: more body and gentle saturation.
• Bass: low shelf, and the high-pass moves down with it.
• Clarity: less mud, more brilliance and harmonics.
• Presence: presence band around 4 kHz, the de-esser follows.
• Compression: threshold, ratio and makeup together.
• Noise red.: noise suppression level and gate range.
• Naturalness: higher = more restrained processing overall.

How your processed voice gets into Discord, OBS, Zoom, Teams and games.

StudioSound Pro writes your processed voice into a virtual audio device (VB-CABLE). Other programs see it like a normal microphone called “CABLE Output”.

• “Send processed voice to the virtual microphone” must be on.
• “Connect automatically” finds the cable and sets everything up.
• “Set as Windows default microphone” makes CABLE Output the system default – programs without their own choice then use your processed voice automatically. “Restore previous microphone” undoes that.

The status tiles show whether VB-CABLE is installed, whether output is running, the format and the latency.

• “Choose folder”/“Open folder”: where the recordings are.
• “Monitor while recording”: hear yourself on headphones.
• The list shows all recordings with date and size.

Before/after comparison (A/B)Normalise, remove silence, crop, export

Hear the difference instantly: A = original, B = processed – in sync and equally loud.

Both tracks come from the same recording and run sample-accurately in sync. Switching jumps to the same spot.

• “Match loudness”: A and B equally loud so you only compare the tone – louder otherwise always seems “better”.
• “Loop”: repeats the selection.
• Click the waveform: playback position; drag: select a range.
• “B live: current settings”: plays the original and processes it with your current controls – ideal for trying things. “Save live version” stores the result.
• “Re-render with current settings” creates track B again.

Simple editing of the recording and export as WAV, FLAC or MP3.

• Normalise: brings the recording to a consistent peak loudness.
• Remove silence: cuts silent beginnings and endings.
• Crop to selection: keeps only the marked range.
• Export …: saves the processed version as WAV, FLAC or MP3 – e.g. for a podcast or video.

Shows how loud your signal is right now – before and after processing.

The coloured bar shows the average level (green → yellow → red), the bright line the last peak. At the top sits the clip LED: it lights up red when 0 dBFS was reached and stays on until you click the meter.

ClippingDecibels (dB) and dBFSGain reduction

The orange bars show how many dB an effect is taking away right now.

Gate, de-esser, compressor, limiter and noise suppression each have their own reduction meter. They grow from top to bottom: the longer, the harder the effect works. For the compressor 3–8 dB while speaking is typical, the limiter should only rarely move.

CompressorLimiter / clipping protectionLevel meter (input & output)

When the signal reaches 0 dBFS, it is cut off and distorts.

Clipping at the input already happens in the microphone or interface – it cannot be repaired afterwards. Lower the hardware gain on the device. At the output, the limiter reliably protects against clipping.

The red LED at the top of the input meter and diagnostics (“Input clipping”) point it out.

Shows live which frequencies are in your voice – original and processed.

Left = low frequencies, right = high, top = loud, bottom = quiet. The grey line is the original, the coloured area the processed voice. You can see, for example, how the high-pass removes rumble or noise suppression lowers the background.

How much of the available processing time real-time processing needs.

For every audio block the PC has only a few milliseconds. The tile shows the share of that in percent. Below 50 % everything is relaxed; from about 80 % dropouts may occur – then choose larger buffers, a lower noise suppression level or close heavy programs.

In the app

“Audio load” tile on the dashboard

Dropouts (buffer underruns)Buffer size (samples)

Counts short audio dropouts when the PC can’t keep up with processing.

A buffer underrun happens when an audio block isn’t finished in time – you hear a short crackle or gap. The occasional one is harmless. If they pile up: increase the buffer size in the settings.

Shows whether StudioSound Pro currently detects speech.

“Speech detected” appears as soon as your voice is recognised, otherwise “Silence”. Detection drives, among others, the auto level (which only adjusts during speech) and helps diagnostics.

Constantly checks your setup and explains problems with a concrete fix.

Diagnostics reports for example:

• No microphone active or connection lost
• Incompatible audio format
• Virtual microphone not installed or not connected
• Feedback risk or monitoring over speakers
• Input clipping, microphone too quiet or no signal
• Background too loud, recalibration recommended
• Audio dropouts or high audio load

Fix ERRORS right away, WARNINGS soon; NOTES are recommendations. If all is good it says “All good – no problems detected”.

StudioSound Pro keeps running quietly in the tray – even without an open window.

• “Start with Windows (in the tray)”: the app starts minimised at sign-in and processes your voice right away.
• “Keep running in the background when closed”: closing the window does not stop processing. Use the tray icon (next to the clock) to reopen the window or quit the app.

Tip Keep both on – otherwise Discord suddenly has no microphone when the window is closed.

Which Windows interface StudioSound Pro uses to record and play audio.

Default is “Windows Audio” (WASAPI) – right for almost all devices. Alternatives such as DirectSound only help with older or special devices. After switching, the devices are reopened.

Sample rate (Hz)Buffer size (samples)

How many times per second the audio signal is measured – 48,000 Hz recommended.

You can choose 44,100, 48,000 and 96,000 Hz. 48,000 Hz is the standard for speech, video and streaming and the only rate the AI noise suppression works with. If a device won’t open, set it to 48,000 Hz in the Windows sound settings (Properties → Advanced) as well.

In the app

How many samples are processed at once: smaller = less latency, larger = more stable.

You can choose 128, 256, 480, 512, 960 and 1024 samples (about 2.7 to 21.3 ms at 48 kHz). Small buffers reduce delay but need a fast PC. If you hear crackles or the “Dropouts” tile counts up, pick the next larger value.
