AU format guide

What to know before converting AU

AU is a simple Sun/NeXT audio container that may hold μ-law, A-law, or PCM samples.

What this converter actually supports

Published audio routes run through the deployed FFmpeg toolchain. The converter probes the source stream before conversion, and files without a decodable audio stream cannot produce an audio result.

WAV is a useful replacement for editing, while MP3 makes old AU clips easier to distribute.

The public upload limit is 1 GB. Convertr does not reduce dimensions, duration, resolution, or output quality merely to manage worker load.

Quality and format limits

WAV, AIFF, and FLAC are appropriate when decoded sample fidelity matters. MP3, AAC, Opus, WMA, and Vorbis are lossy; choose bitrate for the destination and do not expect a higher number to restore source detail.

Telephony-rate μ-law or A-law sources remain limited in bandwidth after conversion.

Published AU inputs

Published AU outputs

Choose one of these implemented routes; a listed extension is not a promise that every codec variant will decode.

If a AU conversion fails

Check that the file opens in its original application, is not encrypted or DRM-protected, and really matches its extension. A damaged header, unsupported internal codec, missing linked asset, or mislabeled file can fail even when AU is generally supported. Try a different published target only when it fits your goal; changing the extension by hand does not convert the file.
