Hi We are working on a speaker phone system using PJSIP and Speex Speech processing API on an ARM platform. Currently we have spent about a month on getting the AEC to work properly and we have worked through the most common causes of problems (such as clock drift, synchronization problems and non-linearity's in echo path). Now we achieve ERLE of about 17 dB which tells me that the AEC is

I have been tyring to use the preprocessor standalone by feeding it pcm data from a headerless pcm file (mono, 22050hz) and then write the result to another file. Unfortunately, all I get back is noise (first frame is set to 0, rest is noise). Frame size is set to 440. I just modified testdenoise.c slightly to read/write from a file (see below) but I can't get useful results. What am I doing wrong? Do I need to perform additional initializations? I am using 1.2rc1, target platform is windows (using Visual Studio). Thank you for your help. ----------------- Modified version of tes...

Hi, I am considering to use Speex in a particular environment and I want to ask if you thought it realistic. I am going to use Wireless SIP (G.711) handsets in an environment that is typcially noisey (background), connecting to an Asterisk PBX. I am considering converting the G.711 to Speex so I can "massage" out the background noise. Is this realistic? Any input would be great.

Hello, With high microphone gain, I seem to have problem making the silence detection work. The speech detection works well for the rare dish sample, which has very low noise amplitudes in silence regions. However, if the microphone gain is set to really high, noise samples are taken as speech, as indicated by the non-zero return value from speex_encode() calls. I had VAD turned on.

Hi, I'm trying to use a denoiser on a wince with a FIXED_POINT defined. Denoiser works OK - it removes the noise, but then it unacceptable hurts a voice. Here is a code that I use: #define TEST_DENOISE_SAMPLES 2000 void test_denoise() { FILE *fin; FILE *fout; spx_int32_t rate=0; int chan=1; int fmt=16; int denoise_enabled = 1; SpeexPreprocessState *preprocess;

Hi all: I was analysising the speex code these days and learned much from it. Thank you so much! But I have a question about VAD: After preprocess(denoise and agc are off, vad is on),the input pcm speech was distorted seriously.The input speech include ten syllables(one~ ten), but the output speech lost one! Can you tell me why? Please see the attachment about input and output: (See attached

Hi! I'm using the newest (beta2) speex library on PocketPC (Windows powered) and experiencing some problems with noise suppression preprocessor turned on while encoding 44kHz files. You can hear the example here: http://szalik.net/speex (this is a 44kHz, 16, mono file encoded in UWB mode) I tried using speex cross-compiled with gcc (fixed point + arm4 asm) and VS (just fixed point) and it

Hello, First of all i would like to say a big thanks for developers of this excellent product. My question is the following: I need to read raw audio data from file and remove from it noise, echo and perform some another stuff. Particularly to remove noise I'm using the "testdenoise" sample as a template. As you know it reads data from stdin. I read it from a file by chunks. Should I make speex encoding of this input data at first, or I can just clear the noise on my stream? If I should, than I can assume that after noise removal the "cleared" data needs to be d...

...44 PM To: speex Cc: Tongbiao Li Subject: Re: [speex-dev] reduction of noise due to high microphone gain Hi, You might want to try the denoiser I've got in CVS (that will go into Speex 1.1 eventually). It will remove stationary noise from the signal and probably help the silence detection. See testdenoise.c for how to use it. There's also a better VAD in the denoiser but speex_encode cannot make use of it yet.

Can you provide me with a backtrace? It's quite hard to see what could happen. Also, can you reproduce the problem with testdenoise or only with your own code?

Hi all, i use speex preprocessor features in this way: =================================== #define NN 160 /* 20msec di audio */ ... int tbc=0,c,d,ret; spx_int16_t TEMP_Buffer[NN]; char DLECODE; /* Inizializza il preprocessore Speex se non inizializzato */ if(Modem->speex_pp_state == NULL) { Modem->speex_pp_state = speex_preprocess_state_init(NN,AUDIO_SAMPLERATE); }

The frame size is 320 Ouss -----Original Message----- From: Jean-Marc Valin [mailto:jean-marc.valin@usherbrooke.ca] Sent: lundi 23 octobre 2006 18:26 To: Ouss Cc: speex-dev@xiph.org Subject: Re: [Speex-dev] Bug with the new preprocessor What frame size are you using?
