Drop in a voice. See what it needs. Open the right tool.
Measure a recording locally, see the strongest signal evidence and open the right repair, transcription, tuning or transformation workflow.
Quick answer: Load one recording into Voice Workbench for a local signal check and up to three useful recommendations, or jump directly to Noise Remover, Speech to Text, Auto-Tune, Vocal Remover or Voice Changer.

Restore recordings & dialogue
Map a complete transfer, remove narrow impulses, correct reference-assisted pitch drift, build matching ambience and fix focused defects instead of applying one destructive pass.
Old Audio Restoration Studio
A complete local restoration desk that maps common vinyl, cassette and tape-transfer defects, keeps every repair decision visible and exports an aligned result with an open archival receipt.
Open Old Audio Restoration Studio β βClick & Crackle Remover
A local restoration editor that finds very short impulsive discontinuities, exposes every candidate as an editable marker and reconstructs only enabled spans from their immediate clean context.
Open Click & Crackle Remover β βΏWow & Flutter Corrector
A reference-assisted pitch restoration workspace that measures time-varying frequency error, separates slow wow from faster flutter and applies a bounded inverse timing correction.
Open Wow & Flutter Corrector β βRoom Tone Maker
A dialogue-repair workspace that finds stable low-variation ambience in a recording and extends the selected texture into an exact-duration room-tone fill.
Open Room Tone Maker β βDe-Reverb
A local room-tail reducer that estimates persistent spectral decay after direct sound and suppresses that late energy while protecting stronger attacks and the original timeline.
Open De-Reverb β π¨Online Plosive Remover
A focused dialogue repair tool that detects short low-frequency microphone bursts and applies bounded low-band reduction only around those events.
Open Online Plosive Remover β πMouth Click Remover
A voice de-clicker that finds isolated millisecond-scale impulses and repairs only the accepted spans with local interpolation and edge smoothing.
Open Mouth Click Remover β π¬οΈVocal Breath Remover
A full-duration vocal editor that detects noise-like breaths between voiced phrases and turns them down without deleting time.
Open Vocal Breath Remover β πNoise Remover
A spectral noise-reduction tool that learns or estimates a noise floor and subtracts it from the recording.
Open Noise Remover β πOnline Hum Remover (50/60 Hz)
A local mains-hum remover that detects or accepts a 50 Hz or 60 Hz fundamental and attenuates selected harmonic multiples with narrow notch filters.
Open Online Hum Remover (50/60 Hz) β πOnline De-Esser
A local high-band dynamics processor that detects strong sibilant energy and reduces the high-frequency component while the detector is active.
Open Online De-Esser β πͺOnline Noise Gate
A local conventional-DSP gate that follows signal level and lowers audio below a closing threshold while opening above a separate threshold.
Open Online Noise Gate βSeparate & understand
Extract parts, map a sung range, turn speech into text or move a clear monophonic melody into editable note data.
Vocal Remover
A two-mode vocal separator: instant phase-based DSP for quick karaoke results, plus an optional neural UVR model for a slower separation attempt.
Open Vocal Remover β ποΈStem Splitter
A fast heuristic stem splitter that estimates vocals, drums, bass and other content with stereo, frequency and transient cues; it is not an AI separation model.
Open Stem Splitter β π§Speech to Text
A transcription page with two modes: browser live dictation and optional local Whisper transcription for uploaded audio.
Open Speech to Text β πΉAudio to MIDI & Voice to Instrument
A local monophonic audio-to-MIDI sketchpad that follows a clear hummed, sung, whistled or instrumental melody and turns it into editable note events.
Open Audio to MIDI & Voice to Instrument β βVocal Range Finder
A monophonic vocal-pitch map that finds reliable voiced notes over time and summarizes the lowest, highest and median detected pitch without changing the recording.
Open Vocal Range Finder βGenerate & transform
Build a vocoder carrier, synthesize speech, match a voice profile you have permission to use, shift formants, build harmony, redesign a voice, correct pitch or arrange spoken audio as music.
Online Vocoder
A real filter-bank vocoder that measures changing energy across a voice or other modulator and applies those band envelopes to a harmonic synth carrier.
Open Online Vocoder β βVocal Formant Shifter
A vocal timbre processor that remaps a short-time spectral envelope upward or downward while aiming to keep the source fundamental pitch and decoded timeline stable.
Open Vocal Formant Shifter β π£οΈText to Speech
A text reader with fast system voices and an optional Kokoro neural voice that runs in the browser after its model downloads.
Open Text to Speech β π§¬Voice Cloning
A voice-profile matching experiment that measures a short sample and selects speech settings that resemble its pitch and speaking style; it does not clone the speakerβs timbre.
Open Voice Cloning β πVoice Changer
A collection of 14 preset Web Audio effect chains for making a recording sound deeper, brighter, robotic, distorted or stylized.
Open Voice Changer β β¬Vocal Harmonizer
A local three-voice harmonizer that renders independently pitched, leveled and panned copies around one source while keeping the decoded timeline length.
Open Vocal Harmonizer β π€β¨Auto-Tune
A local vocal pitch-correction tool that uses bounded YIN/CMNDF tracking to move confident monophonic regions toward a selected key and scale.
Open Auto-Tune β π£οΈπ΅Speech to Song
A playful speech effect that tracks spoken pitch and combines it with procedural drums, bass and chords.

Limits and privacy
Core browser DSP keeps selected audio on the device and avoids an upload queue. Optional model-based or system-speech modes are disclosed on their own pages. Practical limits come from decoded duration, channel count, algorithm memory and the current device; compressed audio can expand substantially in memory.
