Free online AWB to MIDI converter

A notation or music-editing program may require MIDI note events instead of an AWB audio file. The conversion is audio transcription, not a lossless format change: it estimates notes from sound and cannot recover the original performance data exactly.

What the AWB format is

AWB is used for audio, but the extension can refer to different audio encodings. It commonly identifies a CRIWARE wave bank, often paired with an ACB cue sheet in games, or an AMR-WB speech recording. Game sound banks are created with CRI Middleware tools; AMR-WB recordings commonly come from speech and telephony systems. Identify which kind of AWB you have before choosing an offline decoder.

What the MIDI format is

MIDI stores musical events such as note pitches, start times, durations, and instrument assignments; it does not store recorded sound. MIDI is useful for editing notes in a sequencer or notation program, changing tempo, and assigning different instruments. It is usually much smaller than audio, but playback depends on the instruments available in the destination software.

How to convert AWB to MIDI

Online on 101convert.com

1. Open the AWB-to-MIDI converter on 101convert.com and upload the file.
2. Select MIDI as the output format and start the conversion.
3. Download the resulting file. The page supports batch conversion; check its displayed per-file size limit before uploading.

Because AWB contains audio rather than note events, the result depends on automatic transcription and may not match the recording exactly.

Offline with desktop software

For a local workflow, first decode AWB to WAV, then transcribe the WAV to MIDI with the free, open-source Basic Pitch tool. Choose the decoder for the AWB variant:

• AMR-WB: FFmpeg can decode AMR-WB audio. Run ffmpeg -i input.awb output.wav.
• CRIWARE wave bank: use the open-source vgmstream command-line tools to decode the bank, for example vgmstream-cli -o output.wav input.awb. If the bank contains multiple streams, decode the desired stream separately.

Install Basic Pitch in a Python environment, then run basic-pitch output/ output.wav. The output directory receives a MIDI transcription. Review it in a sequencer or notation editor and correct missed notes, pitch errors, and timing; transcription quality varies with the source audio.

Quality and limitations

MIDI transcription works best on clear, pitched material with distinct notes. Speech, percussion, dense mixes, reverberation, and overlapping instruments can produce inaccurate or incomplete note data. A CRIWARE bank may contain several separate sounds, so decode the relevant stream before transcription. If you need to preserve the recording itself, convert AWB to an audio format such as WAV instead; MIDI cannot retain its timbre or waveform.
