Hi all, In commit 3eb4094b859 I think I have fixed all the cast-align warnings. I have tested this in amd64/Linux (little endian) and powerpc64/Linux (big endian) and it passed all tests (including the new MD5 tests). I also did a little performance testing on amd64/Linux with a one hour long stereo WAV file and could not find any mesasurable difference between the old and the new code. I

samples in FLAC are always signed. they must be signed going into the encoder (flac converts unsigned samples to signed) and they come out of the decoder signed.

Hi all, I'm attempting to encode raw audio data using libFLAC++. My audio data is 16 bit, mono, 16000Hz. I set all the appropriate parameters on the encoder and then call init(). Everything appears to be ok. I don't know how to properly convert from char *data to the FLAC__int32 *[] requested by the process function. I think this is where my problem is. If I call process() like this:
