Audio Editing, MIDI and Exports
Which browser tool to use for trimming, converting, mixing and full editing, how the MIDI tools fit together, and what each one exports — most of them free and without uploading anything.
Most editing in Aimusicis happens in your browser: the file is opened on your device, processed there and saved as a download. These tools use no credits and work without an account, except where noted.
Quick jobs
| Job | Tool | Exports |
|---|---|---|
| Change a file's format, quality or channels | Audio Converter | MP3 (128–320 kbps), WAV, FLAC |
| Keep part of a recording, or cut part out | Audio Cutter | MP3, WAV, FLAC |
| Layer tracks at their own levels and starts | Audio Mixer | MP3, WAV, FLAC |
The converter takes up to 10 files at a time; the mixer up to 8 tracks. Each accepts files up to 90 MB and 15 minutes.
Full editing
The Online Audio Editor is a waveform editor for anything the quick tools do not cover: several edits in one file, effects (gain, fades, normalize, compressor, EQ, reverb, delay, distortion, limiter, speed, reverse, remove silence), microphone recording, and a multitrack view.
- Open files up to 100 MB holding up to 12 minutes of stereo or 25 minutes of mono audio, or record takes of up to 10 minutes.
- Signed in, you can open a song from My Music; this needs download access, which is included with a paid plan.
- Save draft keeps your session in this browser for your account. Drafts are not cloud backups — export to keep a copy.
- Export from the File menu as MP3, WAV or FLAC.
MIDI
| You have | You want | Tool |
|---|---|---|
| A text idea | A MIDI composition | AI MIDI Generator |
| A MIDI file | To edit notes in a piano roll | MIDI Editor |
| An audio file | Its melody as MIDI | Audio to MIDI |
| A video | Its melody as MIDI | MP4 to MIDI |
| A MIDI file | Audio you can play anywhere | MIDI to MP3 (renders a WAV) |
| A MIDI file | A score to print or save as PDF | MIDI to Sheet Music |
| An audio file | Its notes as a printable score | Audio to Sheet Music |
The AI MIDI Generator is a generation and draws credits; the other MIDI tools run in the browser for free. Audio to MIDI follows one melodic line, so it suits a sung or played melody better than a full mix — separate the part first with the Stem Splitter if needed. The MIDI editor and MIDI to MP3 accept files up to 5 MB, and MIDI to MP3 renders up to 3 minutes of playing time. Both sheet-music pages write a piano score (MusicXML, or print and PDF from the browser); drum tracks are left out of it.
Exporting songs you generated
Generated songs are downloaded from My Music as MP3 or lossless WAV (a paid-plan feature); see Find, Share and Download Songs. To process one in the browser tools, download it first, or open it in the online audio editor from My Music.
