- SatDump has been incorrectly reading and writing all cs16 recordings (except for ziq2). Reason: scaling was done incorrectly. This means all old cs16 recordings from SatDump are scaled slightly incorrectly, but data can still be recovered from them - Add support for CS32 and CS32 wavs for interoperability - Fix crash when invalid wav is loaded
