Convert MID to AU

There are strong reasons to convert MID to AU:

Collaboration ease: Team members and collaborators are more likely to have software that opens AU Audio natively, reducing compatibility friction.

Smaller file size: Efficient compression in AU Audio often produces significantly smaller files than MIDI File, saving storage space and bandwidth.

Faster loading: AU Audio files decode faster on most systems, reducing wait times when opening or streaming content.

Legacy system support: AU Audio is backward-compatible with older systems that may not support newer or proprietary formats like MIDI File.

Future-proofing: AU Audio has decades of proven stability and will remain supported for years to come.

Converting MID to AU with Xonvert is straightforward:

1. Select source — Upload your MID file using the button above. You can also paste a file from your clipboard (Ctrl+V).
2. Smart settings — Xonvert analyzes your source file and recommends optimal AU encoding settings automatically.
3. Convert now — Click Convert. The entire process runs in your browser with zero server interaction.
4. Grab your file — The AU output appears in the results area. Click to download or drag it to a folder.

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. Quality in this conversion depends primarily on your source file. A high-quality MIDI File input produces an excellent AU Audio output. Since the target format is lossless, output quality matches your input exactly.

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 MID to AU conversion applies format-appropriate algorithms to ensure maximum data fidelity. Standard MIDI File (SMF) format Type 0, 1 or 2
