But when I try this: m_pPreprocess= speex_preprocess_state_init(m_nSamplesPerFrame, m_nSampleRate); speex_preprocess_ctl(m_pPreprocess, SPEEX_PREPROCESS_SET_DENOISE, &tmp); and add speex_preprocess(m_pPreprocess, buf, NULL); before encode. The result is really unacceptable. I think there must be something wrong. And for the encode I did not use abr or vbr because I can not make them work. Does the DENOISE really working in this ver?

...st be a simple issue, but I cannot figure it out. I want to use VAD, but I don't know how to check if the actual frame has voice in it or not. So, in my code, I do: int tmp = 1; speex_preprocess_ctl(preprocess_state, SPEEX_PREPROCESS_SET_VAD, &tmp); speex_preprocess_ctl(preprocess_state, SPEEX_PREPROCESS_SET_DENOISE, &tmp); then later, for each frame speex_preprocess_run(preprocess_state, shortPointer); but how do I know if the frame contained voice? I tried if (preprocess_state->was_voice == 1) { ...Do voice present code... } But the compiler complains that was_voice is not defined, which, I ass...

...le 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

I believe there is a documentation error regarding speex_preprocess_ctl(preprocess_state, request, ptr); The manual states: SPEEX_PREPROCESS_SET_DENOISE Turns denoising on(1) or off(2) SPEEX_PREPROCESS_SET_AGC Turns automatic gain control (AGC) on(1) or off(2) I noticed that setting a value of 0 turns the setting off. Setting a value of 1 or 2 turns the setting on. While I do think 1 and 0 is more logical, it contradicts the documentation. -- Greg...

Interestingly enough.. I started playing around with preprocessing options in 1.1.6 and happened upon the denoise filter (SPEEX_PREPROCESS_SET_DENOISE). When i run the test tone using that option it is completely filtered out and I just get (complete) silence. When the test tone is intermixed with regular voice I only get the voice. So while i still don't quite understand why the test tone dorks up the encoder, it looks like I have a way arou...

Hi, Tank you for your reply. I have tried the sample programs given the manual and done encoding and decoding a wave file. That is working fine. I have already read the manual and API reference. But this problem did not occured with the wave file encoding/decoding. While capturing the data from MIC and encoding/decoding is giving this problem. Thanks and Regards, Vijender Reddy, -----
