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

I'm attempting to use speex preprocess for automatic gain control in an application I'm working on and could use some help. I'm using Opus as my codec. In order to keep the number of packets down, I'm using 60msec frames. I'm sampling at 48KHz as is recommended for Opus. So, the frame length is 2880 samples and the sampling rate is 48000. The source of the data is a

Hi Everyone, I am still unable to start Asterisk 1.4 that I installed using ATrpms. I was initially suspecting some permissions issues but it seems to me that its more to do with a speex codec not loading properly. Here is the message I get if I run asterisk -cvvvvvvvvvvvvvv app_userevent.so => (Custom User Event Application) == Parsing '/etc/asterisk/codecs.conf': Found --

But if you think it helps, I can compile gcc 4.1 and give it a shot. >> Compile flags: >> DEFINES +=

Hi, I'm trying to use Speex Echo Canceller for mobile device. The AEC works well so far. However, I want to know how to remove reverberation significantly. I noticed it's not implemented yet in Speex AEC. Are you going to implement it in next version? Could you provide some ideas how to handle reverberation on current version? Thanks in advance. Sincerely, Dennis

I'm running 1.6.1.18 on an older ubuntu machine. I upgraded to dahi-linux-2.3.0. That went fine, and it works. But I decided to use the opportunity to upgrade to 1.6.2.6. That didn't work. configure, make menuselect, make, make install all went fine, or at least seemed to. But it hangs starting up here: [Apr 13 20:15:28] VERBOSE[1612] codec_speex.c: -- CODEC SPEEX: Setting

I'm having trouble with the preprocessor's noise reduction feature. The basic issue is that it simply doesn't work very well. With my laptop (whose microphone is otherwise quite capable) I routinely hear transient background noise, typing, and other "quiet" sounds leaking through to the speex stream. Even worse, the AGC feature is blowing these things up into just awful

Hi Jean-Marc, I got to this mailing list while trying to use the latest SPEEX version (1.2rc1) VAD capabilities. I had difficulties to successfully distinguish speech from non speech on recorded files (probably doing something wrong). Digging into the code I found out a remark saying :"*The VAD has been replaced by a hack pending a complete rewrite*". In search for answer I found out
