As a silly test, I encoded the Spanish versions of the Sherlock Holmes' volumes (XZ compressed each one) to FLAC with minimodem --tx 300, and later I converted them to Opus at 64 Kbps.

Each file weighted less than 30MB, not bad at all. The raw WAV files were around 400MB each.

The files were re-read back with minimodem --rx at the same rate and dumped back to an XZ file, the sha512sum matched the originals.
