AU to MIDI Quality Analysis
File size after conversion depends on the content complexity and your quality settings. MIDI File preserves all data losslessly, so output size depends on the content's inherent compressibility. MIDI and MID files are identical in content and purpose For the best results, start with the highest quality AU Audio source file available. MIDI File is known for universal music notation format for electronic instruments. This means your converted output will benefit from MIDI File's core strengths. Meanwhile, the original AU Audio's advantage of simple format with wide Unix/Linux tool support may not fully carry over, depending on MIDI File's capabilities.
Audio conversion from AU Audio to MIDI File 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 AU to MIDI conversion applies format-appropriate algorithms to ensure maximum data fidelity. Supports mu-law, A-law and linear PCM encoding

What You Need to Know About AU to MIDI
Can I preview the MIDI output before downloading?▼
Yes. Xonvert shows a preview of your converted file so you can verify the result before saving it to your device.
Can I convert password-protected AU files?▼
Encrypted or DRM-protected files cannot be converted. You'll need to remove protection first using the original software.
Can I convert multiple AU files at once?▼
Yes! Drag multiple files into the converter for batch processing. All files convert simultaneously and can be downloaded as a ZIP archive.
What's the maximum number of files I can convert at once?▼
Free users can convert several files per batch. PRO users enjoy unlimited batch sizes. For very large batches, your device's memory is the only practical limit.
Why choose MIDI over other formats?▼
MIDI File offers universal music notation format for electronic instruments. It's widely used for music production, electronic instruments and score exchange, making it an excellent choice for most audio needs.
Will my AU file be deleted after conversion?▼
No. Your original AU file is never modified or deleted. Xonvert creates a separate MIDI copy — your source file remains untouched.
What audio quality settings should I use?▼
For music, use 256 kbps or higher. For voice/podcast, 128 kbps is sufficient. Lossless output preserves everything.
