Hi Steve,
I hear what you are saying but the code:
/* OK main loop */
while(fread(speech_in, sizeof(short), n_speech_samples, fin) ==
<- reading the input, ints or chars, shouldn't matter in a
Little Endian system.
n_speech_samples) {
if (use_codectx == 0) {
/* Use the freedv_api to do everything: speech encoding, modulating
*/
freedv_tx(freedv, mod_out, speech_in);
} else {
int bits_per_codec_frame = codec2_bits_per_frame(c2);
int bytes_per_codec_frame = (bits_per_codec_frame + 7) / 8;
int codec_frames = freedv_get_n_codec_bits(freedv) /
bits_per_codec_frame;
int samples_per_frame = codec2_samples_per_frame(c2);
unsigned char encoded[bytes_per_codec_frame * codec_frames];
unsigned char *enc_frame = encoded;
short *speech_frame = speech_in;
float energy = 0;
----------
Sort of indicates our input is going to be Codec2.
Looks like I've more work to do....
