...orrect for compressing audio? The output I get is so extremely small, but what is more important: if I pass it through zlib, it gets at least 50% smaller! Init: int bitrate = max_bandwidth * 8; speex_bits_init(&libspeex_bits); if (sample_rate > 22050) libspeex_enc_state = speex_encoder_init(&speex_wb_mode); else libspeex_enc_state = speex_encoder_init(&speex_nb_mode); speex_encoder_ctl(libspeex_enc_state, SPEEX_SET_SAMPLING_RATE, &sample_rate); speex_encoder_ctl(libspeex_enc_state, SPEEX_SET_BITRATE, &bitrate...

On regular data, gzip might get a 5% reduction, so I doubt you can get 50% unless you're encoding zeros or doing something wrong... > if (sample_rate > 22050) > libspeex_enc_state = speex_encoder_init(&speex_wb_mode); > else > libspeex_enc_state = speex_encoder_init(&speex_nb_mode); In normal operation, narrowband is 8000 Hz, wideband is 16000 Hz and ultra-wideband is 32000 Hz, so I'd change the 22050 for something like 12000 (and m...
