MIDI Data
AudioMID generally stores MIDI performance data rather than recorded waveforms. It sends notes, timing and program/control information to a synthesizer, so sound depends on available instruments and settings.

- Storage of notes, timing and performance/control data

Choose your environment or purpose to see its steps.
Menu labels and support vary by app, OS and version. Preserve the original before making changes.
Troubleshooting by symptom
- No sound: check routing, synthesizers, mutes and instrument assignments.
- Different timbres: compare instrument libraries, programs and drum mappings.
- Timing differs: review imported tempo information and project settings.
- No sound: check track output, instrument, channel and mute settings.
- Instruments differ elsewhere: check the sound library and program-change interpretation.
- Overly complex score: distinguish performance timing from notation quantization.
MID → WAV / MP3
- Set instruments, tempo and levels in a rendering-capable DAW and audition the performance.
- Render audio and check the ending, reverberation and silence; retain the MIDI source.
- Inspect tempo, instruments and reverb in the rendered audio; retain MID and instrument details.
Rendered audio loses direct note/program editability; MP3 cannot reliably recreate the original MIDI.
MIDI data versus recorded sound
An instrument interprets notes, timing, controller data and patch selection; MIDI is not a recording of the original voice or performance.
Identical MID data can sound different with different instruments. Record libraries, settings and the DAW project for reproduction.

Checking audio and notation output
For audio inspect tempo, patches, clipping and reverb tails; for notation inspect meter, durations, parts and spelling.
Retain the original MIDI and save edited instructions separately from shared audio.

| Format | Main role | Selection notes |
|---|---|---|
| MID / MIDI | Performance instructions | Requires an instrument |
| WAV / MP3 | Rendered audio | Different from note editing |
| Score distribution | Requires notation review |
Handling and security
Install instruments/plugins from authentic sources; do not run unfamiliar executables merely to play a file.
Questions and answers
Does it contain recorded singing?
Normally it contains performance data rather than recorded vocals.
Why does the same MID sound different?
Synthesizers and instrument mappings may differ.
Can I rename it WAV?
Render the performance through instruments instead.
Can I rename MID to MP3?
It does not create audio. Render the performance using an instrument.
Will importing into Audacity create MP3?
Reading a note track differs from synthesizing audio. Use an application that can render through an instrument.
