How come the clean reference wav file is 168KB, while the clean Lyra (@3kbps) wav file is significantly larger at 328KB?

- walrus01 6y agoSince a browser can't play lyra I think they took the lyra output and put it inside something lossless like a 44kHz stereo wav so that people can listen to it.
- bscphil 6y agoWhen they converted back to wav from Lyra, they used a 32 bit 16 Khz wav instead of 16 bit 16 Khz wav like the source. The size of the Lyra file is almost exactly 2x as big as the reference. Note that this isn't cheating in any way, the source is the source, so it's just a quirk from their conversion process. Probably the tooling around Lyra is pretty rudimentary and the decoder could only output a 32 bit file.
