I'm sorry if this has previously been asked, but I was unable to find anything pertaining to it.
I encoded a WAV into FLAC and calculated the MD5 for each and converted it back. Both WAV files had the same checksum, but when I did --show-md5sum it gave me a compltely different value, that value didnt match the FLAC or the WAV. If the result of the --show-md5sum is supposed to be different what is that hash calculated from? Thanks, Pete |

http://flac.sourceforge.net/documentation.html says:
"Also included in the STREAMINFO block is the MD5 signature of the unencoded audio data." So --show-md5sum (.flac) != md5 (.wav) but: --show-md5sum (.flac) == md5 (.raw) .raw is audio data only.. no headers, no riff chunks.. (.raw = .wav - nonAudioData) on my machine, flac.exe decodes to .raw via flac -d --force-raw-format --sign=signed --endian=little <flac-file> |
