Hi all, I'm getting some noise gate like effects on our sip lines & I think I need to disable silence supression, I'm searching docs & not finding where this can be set, does * have a setting to turn this off? basically what's happening is when we stop talking, the other end hears total silence, but when we talk, they can hear the background noise in the office, this sounds odd

I upgraded from 1.0.9 to 1.2.1. In 1.0.9 everything worked perfect. Now, I call in my IVR, and after navigating in menus when I get dialtone for dialing extension, Sound is choppy and I get bunch of messagess: -- Silence suppression is disabled (option_silence_suppression=0 chan->timingfd=30) -- Silence suppression is disabled (option_silence_suppression=0 chan->timingfd=30) -- Silence

Okay, you've answered part of my question, which is "What value equals silence?". I assume then that a (decoded) frame of silence would be a buffer the size of my frame (320 bytes) full of 0's. Passing this frame (a frame of all 0's) through the encoder causes it to blowup though.. In response to your answer below, I don't think I want to overwrite the decoded

hi, I was wondering how perfect silence frames (no audio at all) in a PCM stream are encoded by the flac encoder. Suppose I have a PCM audio file with some perfect silence frames in the beginning and at the end of the audio recording and suppose I have the same audio file but without the silence frames in the beginning and at the end (so the second file is identical except for the silence frames

I am currently experiencing intermittent silences with my asterisk system. The symptoms are as follows: * Both for incoming and outgoing calls, I (and other users) occasionally experience a brief period of silence. * The silence lasts anywhere from 3 to 10 seconds. * It is not due to silence suppression, because the silences generally occur in the middle of sentences. * Silences occur at

I have a call server that runs on a few custom AGI scripts initiating calls and then managing the calls. I'm getting stuck on the detecting silence functions. I wanted to use the silence detecting as a quick method of substituting Answering Machine Detection. However, whenever WaitForSilence is supposed to be detecting silence, it always just ends the interval whether or not there is

Hi, Speex is great! We are using it to compress hundreds of megabytes of speech for use in our application that trains people in resuscitation. The previous version of our product used Ogg Vorbis, but after switching to Speex, we achieve fantastic compression, while retaining super quality. That allows us to cram more translated versions of the software onto each CD-ROM, making everything

hi, How do i detect whether there is silence in media using speex? Is there any API which decides that the audio data only contains silence? Basically i will have PCM linear data, I want to know whether it is complete silence. Is it that during encoding speex_bits_write will return a lesser number if the audio at byte_ptr contains silence? thanx, Rahul -- Rahul Arvind Jadhav

Which batch programs should I be looking for? I had a look around, and could not find any... The reason speexenc seems like a good place to do this, is that it already have the routines to

Hello! As I see there is dsp_drop_silence switch in confbridge. Could you tell me how asterisk detects silence? Is it possible to change silence level, so, let's say some not loud enough background noises will be recognized as silence and only loud enough human voice will be recognized as sound? Thank you!

Hi, I'm new to this list. I'm using Speex as the base codec in a voice chat application (with DirectSound as the audio playback/capture interface). To help me debug some of my network-related issues, I would really like to insert frames of "silence" into speech. Is there a convenient function call or API call that takes in a buffer that is the size of a frame and writes a

I've tried to transfer a call using the Flash command, but with my configuration it doesn't work. I have a traditional PBX connected with a zap channel to Asterisk that acts like an IVR: TELCO line --> traditional PBX (FXS) --> (FXO) Asterisk >From the TELCO line I can make a call to the traditional PBX and reach Asterisk, the IVR system on Asterisk answers the call and I can

In what fashion does the encoder 'blowup' when passed a frame of zeroes to encode? What version of speex are you using? ________________________________ From: Chris Cowden [mailto:ccowden@ncsoft.com] Sent: Thursday, 15 February 2007 7:57 AM To: David Hogan; speex-dev@xiph.org Subject: RE: [Speex-dev] frame of silence Okay, you've answered part of my question, which is

Completely new topic, and perhaps more important than it might appear just at a casual glance, if one hasn't been thinking about -- and really wanting to write -- some possible future (istic?) applications (as i have . . . and do). What i would like to have, which would _very_ much simplify what's involved in writing the code for certain things i have in mind, is (let me just say this and

Per my conversation below with digium, are there any legal alternatives to digium's G729? It is out of date, and doesn't support VAD nor silence detection. Digium has stated that they have no plans to update it anytime soon. VAD/Silence is a big deal with major carriers and we are having to fight a battle to get them to make special arrangements to turn off VAD/Silence in their

Jesus, Unfortunately, FFT and magic algorithms don't work (yet?). You might want to try this if you're not satisfied with Speex VAD: http://lists.xiph.org/pipermail/speex-dev/2008-August/006860.html It won't perform any miracles, but I think it works pretty well and is easy to tweak.

Does anyone how you might detect a period of x milliseconds of silence using AGI ? Rgds, Stuart

As has been noted before on this list, the Wait() application does not listen for keystrokes from users. Many of you, like me, have looping Background(), Wait(), and Goto() application priority chains that prompt users to enter some data, and then repeat the instructions if no keys are pressed. The problem of course is if the user doesn't start pressing keys during the Background() call
