Re: Reg. FLAC decoding
...#39;re treating the samples
in buffer[] as packed 16 bit numbers.
but all samples in buffer[] are 32-bit signed integers in host
order, regardless of the bits-per-sample of the frame. so to get
them down to shorts (assuming they'll fit), do like:
FLAC__int32 * LChannel = buffer[0];
short TempSource = (short)LChannel[LPos];
instead of
LChannel = (unsigned char *)buffer[0];
short * TempSource = (short *)&LChannel[LPos];
etc.
also, it's probably faster and safer to get the #channels,
bits-per-sample, and sample rate from the the frame header
itself, e.g.
channels = frame->h...

I tried this., but still i dont get the proper output. I'm still
debuggin...
