How do I convert an OPUS file to SOU online?

Upload your OPUS file to the OPUS-to-SOU converter, choose the SOU preset (default 48 kHz stereo), click Start, and download the resulting .sou file. No desktop software is required.

Why would I convert OPUS to SOU?

OPUS is a highly compressed lossy codec optimized for streaming, while SOU is an uncompressed PCM container used by older DAWs and game engines. Converting to SOU gives you bit-exact PCM playback in software that has no Opus decoder, at the cost of a much larger file size. It also lets you edit the audio sample-by-sample.

How does OPUS to SOU conversion affect sample rate, bit depth, and channels?

The converter decodes OPUS to linear PCM at the original sample rate and channel count embedded in the Opus file. Bit depth is expanded to 16-bit or 24-bit depending on the SOU preset; the lossy Opus compression artifacts remain, but no additional resampling or channel mixing is applied. If your source is 48 kHz stereo, the SOU file will also be 48 kHz stereo.
