There's also a usecase of using flac for non-audio data: anything that looks like a waveform compresses quite well. e.g. analog signals, data logging, etc. One example is https://github.com/oyvindln/vhs-decode https://github.com/oyvindln/vhs-decode - capturing high-bandwidth signals directly from analog tape with SDR-like hardware, for later software demodulation. Those waveform signals compress quite well with flac. Currently there's flacCL, which compresses on the GPU, so this is one more option.
