Audio processing SaaS
One upload. Every audio tool you need.
Split stems, clean up vocals, master, analyze and convert, powered by open-source models with clean licensing. Pay with credits; results land in your library, ready to chain into the next tool.
Free tier includes 30 credits/month. No card required.
Private by default
Your uploads auto-delete, and we never train on your audio. Clear retention, no surprises.
Trust through measurement
Every result ships a metrics table (LUFS, true-peak, duration, key), so you can verify, not guess.
Reproducible
Each output stores its full parameter set, so any result can be regenerated or tweaked.
The toolbox
Launch defaults shown; longer files are quoted proportionally, always with the price before you run.
Separate
Pull a mix apart into clean, separate tracks you can remix or reuse.
Split vocals from music
Separate any song into two clean tracks: the vocal on its own and the full instrumental behind it.
Split into 4 stems
Break a song into four separate tracks (vocals, drums, bass and everything else), ready to remix or remaster.
Split into 6 stems
Separate a song into six tracks (vocals, drums, bass, guitar, piano and other) for detailed remixing.
Make a karaoke track
Removes the lead vocal so you can sing along, and hands you the isolated vocal too.
Split film audio
Separates a film or video soundtrack into three tracks: dialogue, music and sound effects.
Clean & Restore
Rescue damaged recordings: remove noise, echo and distortion, and repair lost detail.
Clean up noisy speech
Removes background hiss, hum and room noise from spoken-word recordings, leaving the voice clear.
Clean up noisy music
Reduces broadband hiss and noise across a full music mix without hollowing out the instruments.
Remove echo & reverb
Takes the room out: reduces reverb and echo so a recording sounds close and dry instead of distant.
Restore a voice
One-pass repair for voice: removes noise, sharpens clarity and rebuilds missing high frequencies.
Repair distorted audio
Fixes recordings that distorted from being recorded too loud, rebuilding the damaged detail.
Restore MP3 quality
Rebuilds detail crushed out by low-bitrate MP3s and other lossy files, for a fuller, less brittle sound.
Fix audio by describing it
Tell it what's wrong in plain words ('too muddy', 'remove the hiss') and it restores and masters to match.
Repair damaged calls
Reduce clipping, short dropouts and compression damage in calls and remote speech recordings.
Enhance
Add back the detail and brightness that low-quality or muffled audio is missing.
Upscale audio detail
AI upscaling that reconstructs crisp high-frequency detail for dull audio. The best quality, but slower.
Brighten muffled audio
Rebuilds the high frequencies missing from dull, muffled or heavily-compressed recordings for a fast fix for lifeless audio.
Sharpen muffled speech
A near-free brightener tuned for the human voice that makes muffled or telephone-quality speech clear and present.
Analyze
Measure what's in a track: tempo, key, loudness, structure, lyrics and more.
Transcribe lyrics
Writes out a song's lyrics with a timestamp on every word, ready for captions, karaoke or subtitles.
Auto-tag genre & mood
Listens to a track and suggests genre, mood and instrument tags, handy for sorting and labelling a library.
Measure loudness
Reports exactly how loud your audio is against streaming and broadcast standards, without changing it.
Find BPM & beats
Detects the tempo and marks every beat and downbeat, giving you the grid you need to sync, loop or remix in time.
Detect key & chords
Finds the musical key of a track and maps out its chord progression over time.
Map song sections
Finds where the sections of a track begin and end (intro, verse, chorus, drop), and groups the similar ones.
Convert audio to MIDI
Turns a melody or instrument recording into editable MIDI notes you can open in any music software.
Transcribe conversations
Turn a podcast or interview into a timed transcript with speaker labels and TXT, SRT and JSON downloads.
Mandarin singing score

Voice
Change, tune, clone or synthesize the human voice.
Change the voice
Makes one recording sound like it was performed by a different voice you provide, whether speaking or singing.
Tune vocals (autotune)
Nudges an off-pitch vocal toward the right notes with subtle correction by default, or hard-snap if you want the effect.
Text to speech
Turns written text into natural-sounding spoken narration, with a choice of voices. No recording needed.
Clone a voice
Give it a short clip of any voice and it speaks your text in that voice. Every result is watermarked.
Change a singing voice
Transfer a reference singer’s voice onto your isolated vocal take while keeping its words and melody.
Generate
Create original music from a text prompt, or extend and rework a track you have.

Rework your arrangement
Try a new style for your music or generate an instrument track around your existing clip.

Change the sound of a selected passage while using the original as a starting point.
Master & Loudness
Get a track to the right loudness and polish for release.
Match streaming loudness
Sets your track to the loudness streaming platforms expect, so it doesn't play back too quiet or too loud.
Master to a reference
Point it at a song whose sound you love and it makes your track match that tonal balance and loudness.
Limiter (raise loudness)
Pushes overall level up to a safe ceiling without letting peaks distort as the final loudness stage of a master.
Time & Pitch
Change speed or pitch independently, without the chipmunk effect.
Convert & Utility
Everyday audio edits: format conversion, trimming, EQ, fades and more.
Convert format
Convert audio between MP3, AAC, Opus, FLAC and WAV, with control over sample rate and quality.
Trim & fade
Cut audio down to just the part you want, with optional fade-in and fade-out at the edges.
Fade in / out
Add a smooth fade-in at the start or fade-out at the end, with a choice of fade shapes.
Change playback speed

Adjust volume
Turn a track up or down by a set amount, or normalize its loudest peak to a target level.
EQ (tone shaping)
Shape the tone by boosting or cutting bass, treble and any frequency between, with presets or precise bands.

Spectrogram image
Render a picture of a track's frequencies over time, useful for spotting noise, cutoffs or fake quality.

Render the classic waveform picture of a track (the shape of its volume over time) as a PNG.
Effects Studio
Creative build-ups, stutters, tape stops and gates for electronic music and DJ sets.
Tape stop
The DJ 'power-down' effect: audio slows and drops in pitch to a halt, like a tape or turntable stopping.
Stutter riser
Builds tension for a drop with a repeat that speeds up and rises in pitch into a climax.
Stutter spindown
The come-down counterpart to the riser: a repeat that slows and drops in pitch to release energy.
Trance gate
Chops a sustained sound into a rhythmic on-off pulse in time with the beat, creating the classic trance-gate effect.
