Hello, I'm using Speex1.1.11.1 source code. I enabled dereverb by speex_preprocess_ctl(). I try different dereverb_level and dereverb_decay values and it seems to not work. I generate some test files in CoolEdit using reverb or echo and then preprocess it by speex_preprocess(preprocess, input, NULL); and output is the same as input:(. Denoising and VAD works very good. I tried dereverb with and without denoise or/and VAD. Are there som...

...buffer, Quality is set to 8, and perceptual enhancement on. The preprocessor state is being set as follows: preprocessorState = speex_preprocess_state_init(320, 16000); //640, 32000 int denoise = 0; int agc = 0; int vad = 0; int dreverb = 0; float agcLevel = 8000; float dereverb_decay = .5f; float dereverb_level = .2f; speex_preprocess_ctl(preprocessorState, SPEEX_PREPROCESS_SET_DENOISE, &denoise); speex_preprocess_ctl(preprocessorState, SPEEX_PREPROCESS_SET_AGC, &agc); speex_preprocess_ctl(preprocessorState, SPEEX_PREPROCESS_SET_VAD, &vad); spee...

Unlivable. I fix it. I forgot the speex_preprocess(m_pPreprocess, buf, NULL) need to do enough samples too. Tks a lot! And speex_preprocess_ctl(preprocess, SPEEX_PREPROCESS_SET_DEREVERB, &tmp); f=.4; speex_preprocess_ctl(preprocess, SPEEX_PREPROCESS_SET_DEREVERB_DECAY, &f); f=.3; speex_preprocess_ctl(preprocess, SPEEX_PREPROCESS_SET_DEREVERB_LEVEL, &f); What are these source code mean? I can not find any document about them. -----Original Message----- From: owner-speex-dev@xiph.org [mailto:owner-speex-dev@xiph.org] On Behalf Of Je...
