MOD to AU Converter
Processing entirely on your device — large files may take a moment.
MOD is the Amiga tracker format — samples plus a pattern table that the demo scene turned into an art form, replayed through its own synthesizer. Converting AU to WAV preserves the samples in a format every modern tool reads.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

About the MOD format
MOD is where digital music composition started for a generation: the Amiga tracker format stores short PCM samples plus a pattern table of note events, and the player synthesizes the song live. It is not a waveform — it is sheet music and an instrument pack in one file, which is why 30KB can hold a full song.
Converting MOD to MP3 or WAV renders the song through the tracker engine exactly as it sounds — every player interprets the same patterns, so the render is faithful to the original scene release.
+ Strengths
- ✓Complete songs in tens of kilobytes
- ✓Rich demo-scene heritage
- ✓Self-contained samples + patterns
! Limitations
- −31 8-bit samples max in classic MOD
- −Player interpretation varies subtly
- −4-channel-era limitations
About the AU format
AU is Sun Microsystems' audio format from the Unix workstation age: a small header followed by µ-law (or PCM) samples. Java's applet era shipped it everywhere, and old Unix sound tooling still emits it.
Modern players increasingly skip it. Converting AU to WAV preserves the samples bit-for-bit while moving the file into universal territory — the standard rescue path for system sounds and old recordings.
+ Strengths
- ✓Simple, lossless sample storage
- ✓Native to old Unix/Java tooling
! Limitations
- −µ-law flavor sounds dated and mono
- −Dropped by modern players
Why convert MOD to AU?
Converting makes sense where the strengths of AU meet what MOD cannot give you. Simple, lossless sample storage Meanwhile 31 8-bit samples max in classic MOD One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this MOD to AU converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for MOD to AU?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Will converting MOD to AU reduce audio quality?
If AU is lossless, the output contains everything the MOD file contains — no further loss is added. If AU is lossy, one recompression pass is unavoidable; the quality slider controls how much. Loss that already happened in the source file can never be undone by converting.
Are tags like title and artist preserved?
Tag handling varies between target formats and this conversion focuses on the audio itself. For archival copies where tags matter, keep the original file; the converted copy is for playback and sharing.
