...VAD is a kludge */" I've seem in te roadmap that you are testing a new VAD, but Im not sure if im doing something wrong with the current. Here is the code of the compressor: if (inicializado == false) { bits = new SpeexBits; speex_bits_init(bits); enc_state = speex_encoder_init(&speex_nb_mode); // obtenemos tama?o frame speex_encoder_ctl(enc_state, SPEEX_GET_FRAME_SIZE, &frame_size); // configuramos parametros int complexity = 5; speex_encoder_ctl(enc_state, SPEEX_SET_COMPLEXITY, &complexity);...

Hi, I'm using the latest version of libspeex (checked out today) and have some problems with checking the target bitrate in the encoder. Calling: peex_encoder_ctl(globals->enc_state,SPEEX_GET_BITRATE, &bitrate); Seems to set bitrate to 24600 no matter what the qualitysetting is.. The functions used previous to this call is: peex_bits_init(&globals->bits); globals->enc_state = speex_encoder_init(&speex_nb_mode); speex_encoder_ctl(globals->enc_state,SPEEX_...

...th 16 bits pcm.

...e mflops for using fixed point on a Win CE compared to using floating point? Looking at the manual, "In practice, frame_size will correspond to 20 ms when using 8, 16, or 32 kHz sampling rate." for a 8 kHz sampling, the framesize should be 320 right? But when i use speex_encoder_ctl(enc_state,SPEEX_GET_FRAME_SIZE,&frame_size) The framesize i got is 160. I am trying to encode the data which is contained as an unsigned char buffer[160] as mode 2 of 5,950 bps and stored as the same data type as unsigned char array after encoding I have managed to link the libspeex_armce.lib file suc...

Hello, I'm trying to use the speexlib but I just can't do it. I've made just like the example (on the site) says. Some times I get SIGFAULT.
