Why convert from OPUS to FSL?

OPUS is a highly compressed audio codec optimized for streaming, while FSL is a lossless container format used by professional audio editors for editing and archiving. Converting OPUS to FSL enables seamless editing in FSL-compatible DAWs without any additional transcode, and keeps the original audio data intact for future processing.

How does the conversion preserve audio quality?

The conversion is a container remux, meaning the underlying audio codec data is not decoded and re-encoded. The original bitrate, sample rate, channel layout, and all metadata tags are preserved exactly as in the source OPUS file. The container is changed to FSL's native format, but the codec payload remains untouched.
