int frameSize; speex_encoder_ctl(enc_state, SPEEX_GET_FRAME_SIZE, &frameSize); Is frameSize in bytes? If not, what unit is it in? I need to know so I know how big to make each element in my circular buffer. Also, do I need to call speex_encoder_ctl( enc_state, SPEEX_SET_SAMPLING_RATE, &sampleRate ); Depending on sample rate I record my audio in? If not, is there any benefit to setting the sample rate, such as reduced bandwidth?

As for me - speex_echo_cancellation is a better choise. Try using it in capture thread instead of those speex_echo_capture and speex_echo_playback functions. And please, describe your problem in details. Cause the fact that you "didn get echo cancellation" doesn't mean you are doing smth wrong. Regards, Anton A.

...ut files. Speex-1.2beta1 crashes with all 44kHz input file and it's very hard to debug, because I'm using .NET P/Invoke to call native DLL and the application just closes down when it crashes. As for the code, it's quite simple, the basic flow is as follows: 1. Init encoder, bits, set SPEEX_SET_SAMPLING_RATE 2. Init preprocessor state, set SPEEX_PREPROCESS_SET_DENOISE 3. Set quality/complexity 4. loop with: encode_stereo, preprocess, encode int Any suggestions as to what I might be doing wrong? Or is it a bug? Maybe something with the last fixed-point changes? -- Piotr Domagalski
