Convert MP3 to XMI

A legacy game or sound tool may accept XMI music data when the available source is an MP3 recording. Because XMI stores sequenced events rather than recorded audio, creating it requires transcribing the music and then converting the resulting MIDI file.

What MP3 stores

MP3 is a lossy compressed audio format used to distribute and play music, speech, and other recordings. It stores an encoded sound waveform, not separate notes or instrument parts.

What XMI stores

XMI, also called XMIDI or Extended MIDI, stores musical events such as notes, timing, and controller changes. It is used mainly by older games and sound systems. Its event data is compact and editable, but playback requires a compatible MIDI synthesizer and sound bank; XMI does not preserve an MP3’s waveform or exact sound.

How to convert the recording

1. Use a desktop audio-to-MIDI transcription tool such as AnthemScore to open the MP3 and detect notes. Review and correct the transcription; separate instruments or enter parts manually when the recording is a dense mix.
2. Export the corrected transcription as a standard MIDI file, such as transcription.mid.
3. Open the MIDI file in Awave Studio and choose File → Save As. Select XMI as the output format and save the .xmi file. Awave Studio handles the MIDI-to-XMI step; it does not determine the notes in an MP3.
4. Test the XMI in the game or sound tool that needs it, since older software may support only particular XMI variants or playback features.

For a browser-based transcription alternative, Spotify’s Basic Pitch can produce MIDI from audio. Inspect its output before converting it with Awave Studio, and do not upload recordings that must remain private.

Quality and compatibility

Audio-to-MIDI transcription estimates notes; it cannot reliably recover every part of a full mix. Chords, overlapping instruments, percussion, reverb, and MP3 compression can cause errors. The resulting XMI will sound different from the recording because it contains note events, not the original audio, and its sound depends on the destination synthesizer and sound bank. If the destination must play the recording unchanged, use an audio format it supports instead.
