Free online AWB to MID converter

Some notation programs, sequencers, and hardware require MIDI files to edit or play notes, while AWB files hold recorded or synthesized audio. Converting an AWB therefore requires note recognition; it does not simply change the file extension or preserve the original sound.

What the AWB format is

In audio assets, AWB usually means a CRI Middleware waveform bank. It commonly accompanies an ACB cue bank and contains audio streams used by games and other CRI Atom applications; CRI tools and game build pipelines create these banks. A single AWB can contain multiple audio streams, often encoded with CRI codecs such as HCA or ADX.

What the MID format is

MID is a filename extension for Standard MIDI Files. A MIDI file stores note events, timing, and performance controls rather than recorded audio, so it can be edited in sequencers and notation software and played using different instruments. It is usually much smaller than audio, but its playback sound depends on the MIDI player or synthesizer.

How to convert AWB to MID

Online on 101convert.com

1. Choose the AWB file on the 101convert.com conversion page and upload it.
2. Start the conversion to MID.
3. Download the resulting file. The page supports batch conversion; its per-file size limit is shown there.

Offline with desktop software

For a local workflow, first decode the relevant AWB stream to audio, then use audio-to-MIDI transcription. Install the open-source vgmstream command-line tools and Spotify’s Basic Pitch Python package; both are available for Windows, macOS, and Linux.

1. Check which stream you need with vgmstream-cli -m bank.awb. AWB banks may contain multiple streams.
2. Decode a stream to WAV, replacing 1 with its stream number: vgmstream-cli -s 1 -o clip.wav bank.awb.
3. Run Basic Pitch on the decoded audio: basic-pitch output clip.wav. The output directory receives a MIDI transcription.

For a commercial alternative, use Celemony Melodyne: open the decoded WAV, analyze it with the appropriate melodic or percussive algorithm, then export the detected notes as a MIDI file using Melodyne’s MIDI export function. The precise export workflow depends on the Melodyne edition and host application.

Quality and limitations

Transcription estimates notes from audio; it cannot recover the original MIDI events, instrument assignments, or timing with certainty. Results vary with polyphony, percussion, effects, and recording quality. If an AWB contains several streams, decode and transcribe each one separately; a MIDI file represents note events and will not reproduce the AWB’s original audio by itself.
