Came across an odd bug - if I try to compress intermediate 64-bit stereo files sampled at 176.4Khz from Reaper (say, to work on them later) and use WavPack, I get 32-bit mono files out. I contacted David as well because I don't think 64-bit support is included in WavPack either. Probably a ridiculous outlier scenario. Don't know why most people would need to compress such files lol but figured I'd let you know!
