Turn a raw recording into a finished episode tonight
Dead air, room hum, four takes to stitch together and a transcript for the show notes — Audio Magic handles all of it in your browser, using the same AI models the paid services run. Nothing is uploaded, and nothing is metered per minute.
Free for 15 minutes of audio per tool, per day. No card, no watermark, no upload.
Every step of the cleanup, in one place
Cut the dead air and the long pauses. Strip the room hum, the fan and the air conditioning off the voices. Stitch your takes into one file, fade the top and tail, and get a transcript back for the show notes and the search engines. It is everything that stands between a recording and something you can publish.
For interviews you cannot upload
Some tape should never reach a cloud service — a source who needs protecting, a client interview, a patient session, an internal investigation. Nothing here is uploaded, so there is no processing agreement to sign and nothing left on a server to delete afterwards. You can check that claim yourself rather than take it on trust: load this page, turn off your Wi-Fi, and every tool still works.
No upload, no queue, no waiting
A two-hour interview spends twenty minutes uploading to a browser tool before it starts doing anything, and then waits its turn behind everyone else. Here the work starts the second you drop the file in, because it happens on the machine you are already sitting at — on a train, on a plane, or with the Wi-Fi switched off.
Free, and honest about what that means
Fifteen minutes of audio per tool per day, with no watermark on anything you export, no trial counting down and no account needed to start. If you outgrow that, a subscription lifts the limits for $4.99 a month, with the first 7 days free. That is the entire business model, and it is the only thing an account gets you.
Every tool, free to use today
Whisper for transcription, DeepFilterNet3 and RNNoise for noise, Demucs for stems, Kokoro and Chatterbox for speech — every one of them running on your own machine.
Transcribe Audio
Turn speech into text or timestamped subtitles, in over 90 languages, using an AI speech recognition model. It runs on your own device, so nothing is uploaded.
Clone a Voice
Record about eight seconds of a voice, then type anything and hear it said in that voice. The model runs on your own device, so the recording is never uploaded. Needs WebGPU and a 1.5 GB one-off download, which is the trade for a voice model this capable running locally at all.
Generate Speech
Type or paste text and hear it read aloud in a natural voice, then download it as WAV or MP3. Fifteen voices in American and British English — twenty-eight if you turn on the low-rated ones — each with a sample you can play first. The model runs on your own device, so nothing you write is uploaded — which also means generating takes about twice as long as the speech it produces.
Detect Sounds
Teach it a sound from a handful of short clips — a dog barking, a gunshot, a doorbell — then find every place that sound happens in a long recording. Exports the timestamps as a subtitle file. Training and detection both run on your own device.
Make a Spectrogram
Turn a recording into a picture of itself — frequency up the side, time across the bottom, loudness as colour. Select any region, pick a palette and an aspect ratio, and export it as a PNG with the axes on for analysis or off for a square you can hang on a wall.
Remove Silence
Cut dead air and silent gaps out of a recording with exact, non-destructive DSP analysis. The waveform shows you exactly what goes before you commit.
Remove Background Noise
Strip hiss, hum, fans and room tone out of a voice recording using an AI speech-enhancement model that runs in your browser.
Separate Stems
Split a song into separate tracks with an AI model — take the vocals out for a karaoke backing track, or pull drums, bass and vocals apart. Runs on your own device.
Convert Audio
Turn MP3 into WAV or WAV into MP3, and the same for M4A, OGG and FLAC. Pick a bitrate and see exactly how much smaller the file gets.
Merge Audio
Stitch a batch of recordings into one long file, or into evenly sized parts. Set how long each output runs before a new one starts, and how much silence sits between files.
Fade In & Out
Ease a clip in and out instead of cutting hard, using equal-power gain curves. Set one fade for every file, or give any file its own.
