trying to write encoder - need help!
...t 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: FLAC__int32 *samplesArray[1] = { (FLAC__int32 *)data }; // data size if 4096 bytes if (!process(samplesArray, 1024)) die("return false"); it appears to encode ok, but when I play the flac file, it plays at twice the normal speed. I can cheat and tell the encoder that the sample rate is really 8000 Hz when in re...
