MIDI to AU Quality Analysis
MIDI and MID files are identical in content and purpose On the output side, Convert AU to WAV for modern audio editing Together, following these practices ensures the best conversion outcome between MIDI File and AU Audio. Dynamic range — the span from darkest to brightest values — is handled carefully during this conversion. MIDI File preserves the full range. AU Audio maintains the complete dynamic range. Xonvert preserves embedded metadata (EXIF, XMP, ID3 tags, etc.) whenever the AU Audio format supports it. Format-exclusive metadata fields that have no equivalent in AU Audio are gracefully omitted without affecting the converted content.
Audio conversion from MIDI File to AU Audio focuses on preserving sonic fidelity while adapting to the target format's characteristics. Both formats are lossless, guaranteeing a bit-perfect audio transfer with no quality change whatsoever. Sample rate, bit depth, and channel layout are preserved when supported by the target format.
The MIDI to AU conversion applies format-appropriate algorithms to ensure maximum data fidelity. MIDI 2.0 (2020) adds higher resolution and more channels

What You Need to Know About MIDI to AU
How long does MIDI to AU conversion take?▼
Most files convert in under 5 seconds. Larger files may take 10-30 seconds depending on your device's processing speed.
Can I convert MIDI to AU in bulk for free?▼
Yes. Free users can batch-convert multiple files. Simply drag all your MIDI files into the converter at once. PRO users get higher batch limits and priority processing.
What's the difference between MIDI and AU?▼
MIDI File is musical instrument digital interface — note and control data. AU Audio is sun/unix audio format for basic audio on unix systems. Key difference: MIDI File excels at universal music notation format for electronic instruments, while AU Audio offers simple format with wide Unix/Linux tool support.
How does the MIDI to AU conversion work technically?▼
Xonvert uses WebAssembly-compiled libraries to decode your MIDI file in-browser, process the audio data, and re-encode it as AU. All processing happens on your device's CPU.
What happens to my files after conversion?▼
Nothing — your files exist only in your browser's memory during conversion. Once you close the page, all data is cleared. No files are stored anywhere.
What is MIDI format?▼
MIDI File is Musical Instrument Digital Interface — note and control data. It is primarily used for music production, electronic instruments and score exchange. Identical format to .mid — only the extension is longer
Will the conversion strip my EXIF or metadata?▼
Xonvert preserves metadata (EXIF, XMP, ID3, etc.) when the target AU format supports it. You can optionally strip metadata in the settings for smaller, cleaner output files.
