How do I convert an AU file to SND?

Upload your AU file using the 'Choose File' button, select SND as the output format, optionally adjust sample rate or bit depth, then click Convert. The processed SND file will appear in the download list. For multiple files, use the batch mode by choosing several AU files at once.

Why should I convert AU to SND?

AU is the native audio format of Sun/NeXT workstations, while SND is commonly used by classic Mac OS applications. Converting removes incompatible headers and makes your audio playable in older Mac editors, media players, or game engines. It also lets you standardize the codec to uncompressed PCM for lossless editing.

How does the conversion preserve my audio data?

If the AU file contains uncompressed PCM, we copy the raw sample data and replace the header. For compressed AU streams like G.711 µ-law, the data is decoded to linear PCM and then written as an SND file, keeping sample rate and bit depth. Loop points and marker data from the AU header are transferred to SND's loop fields when present.
