How to convert MIDI to WAV
- Step 1
Open your MIDI file
Choose a .mid or .midi file, or drop it on the box. It is read by your browser and never leaves your device.
- Step 2
Convert to WAV
Press Convert. The notes are played with the instruments set in the file and recorded to lossless audio.
- Step 3
Listen and download
Check the result in the audio player, then download the WAV and drop it into any DAW or video editor.
MIDI to WAV or MIDI to MP3?
WAV is uncompressed: it keeps every detail of the rendered audio, so it is the right choice for editing, mixing, video soundtracks or further processing. It is also large — about 10 MB per minute of stereo audio.
MP3 is compressed for listening and sharing and is about a fifth of the size. For a file to send or play on a phone, use the MIDI to MP3 converter.
Going the other way, from a WAV recording to MIDI notes, is what the WAV to MIDI converter does.

Convert MIDI to MP3 →Frequently asked questions
What format is the WAV file?
Stereo, 16-bit, 44.1 kHz PCM — the CD standard that every DAW, video editor and audio app opens. The level is normalized so the loudest moment reaches full scale without clipping.
Can I get each instrument as a separate WAV?
Not yet — the converter renders the whole song to one stereo file. To get stems, mute the other tracks in your DAW and export each one.
Is my MIDI file uploaded?
No. The MIDI file is played and recorded inside your browser, and the audio file is made on your device. Nothing is sent to our server, so there is no daily limit.
Which instruments does it use?
The 128 instruments and the drum kits of General MIDI, from the GeneralUser GS sound bank. Each track plays with the instrument chosen in the MIDI file — piano, strings, guitar, bass, drums and so on.
Why does it sound different from my DAW?
A MIDI file holds notes, not sound, so every player picks its own instruments. Your DAW may use other sample libraries or plugins; to get exactly that sound, export the audio from the DAW itself.
How long can the MIDI file be?
Up to 10 minutes of music and 2 MB. The first conversion downloads the instruments (about 8 MB); after that they come from your browser cache.
Can I turn an MP3 back into MIDI?
Yes — that is the other direction. Use the MP3 to MIDI converter to get the notes of a recording as an editable MIDI file.
