Millions of ordinary people have systems that do not meet your stringent specifications. It does not matter what OS you or I use. It's the customers for whom this work is done. -----Original Message----- From: Jean-Marc Valin [mailto:Jean-Marc.Valin@USherbrooke.ca] Sent: Monday, July 02, 2007 6:35 PM To: Coffey, Michael Cc: speex-dev@xiph.org Subject: RE: [Speex-dev] Backup Echo Suppression

Jean-Marc, I think I can speak for most everyone here when I say we appreciate *very much* your code beyond the codec that helps people who use Speex in real applications. How far you want to take that code is up to you, of course. (And contributors, to a degree.) I don't think any reasonable person is expecting your code to solve everything. But when people are running up against

Believe me; I've "played with" priorities and buffering. Did you just say you have no idea how the Speex residual echo suppressor works? If that is the case, can you tell me where I could get some information about it? -----Original Message----- From: Jean-Marc Valin [mailto:jean-marc.valin@usherbrooke.ca] Sent: Friday, June 29, 2007 7:38 PM To: Coffey, Michael Cc:

It appears that both the echo canceller and the noise reducer (NR) introduce rather severe clicking artifacts when presented with audio that has slightly overloaded the A/D converters. I am talking about speech that sounds just slightly distorted, due to clipping, when simply played back. If I pass that speech through the echo canceller or the noise reducer, it acquires really loud clicks and/or

I realize that the preprocessor echo suppression is not designed specifically to counter the effects of data loss. On the other hand, as much as I might like to, I do not have the option to "fix that problem for real." The sad truth is that some end users have systems that may drop samples, or do other unfathomable things, no matter what I do. I can not rewrite their drivers, firmware,

Svn Log is my favorite! (Butm generally with the Tortoise front-end FWIW. I don't think I've changed anything except back when we needed the AEC patch or to make a project file build. -----Original Message----- From: Jean-Marc Valin [mailto:jean-marc.valin@usherbrooke.ca] Sent: Monday, June 11, 2007 4:27 PM To: Coffey, Michael Cc: speex-dev@xiph.org Subject: Re: [Speex-dev] RE: Moving

Has it been a whole week since a question about VAD? :-) I am curious why the VAD algorithm described in G.729 Annex B is not used by Speex. Complexity, Patent, Quality, or what? -mjc

Aha. By "frames" I assume you mean 10ms or 20ms or whatever I have passed as frame_size to speex_echo_state_init. Correct? (I suppose I could go to a smaller frame size if desiring finer precision.) I gather that prop[] contains proportional adaptation rates. I guess I'll have to read up on the MDF algorithm to get a better sense of what that means. Thanks -----Original

Hi Folks, I am having trouble using speex_echo_cancel. As a starting point, I am using the testecho.c source code. I compiled the 1.2beta1 version. I have not tried any other versions of speex. The document says that the order of arguments to Speex_echo_cancel is (echo_state, input_frame, echo_frame, output_frame, residue) where "input_frame" is as captured from mic and

What is the current status of the residual echo suppressor in the preprocessor? I ask this because I have occasional problems with the AEC, in which it fails to cancel echo. I think the problems have to do with samples being dropped by the audio IO system, which is effectively impossible to detect and counteract reliably. A colleague recommended using an echo suppression technique (which he

Here are some notes/observations I've done on my setup that works for me. Hopefully it will be added to some r-forge documentation/wiki. I use: Windows Vista Business SP2 32bit TortoiseSVN 1.6.7 (Build 18415 - 32 Bit , 2010/01/22 17:55:06) PuTTY v0.60 (with Pageant v0.60) I have a deprecated r-forge project ('r-oo') that I will use through out. My r-forge username is

Hi everyone, I would need to know if RoR follow any policy for version naming; I mean, something like linux´s kernel does or similar. For instance, kernel uses numbers separated in groups by dots (i.e. pre 2.6 - AA.BB.CC). These groups mean differents fixtures, bugs fixed... I will start a big proyect from scratch with rails and I want to choose now a standart to use and avoid future problems

Caveat: this is not a discussion about *hosting* a rails app on windows. Anyway...Macs are everywhere you look when researching rails (demo vids, tutorials, and pictures from rails training classes). I''m interested in what the pros to using a Mac for rails development are (besides textmate). Is it more of a cultural thing, a what would 37 signals do thing, is it a unix thing, or

First time here, so I hope this isn''t a FAQ (although I did check *the* faq). I''m using mongrel_cluster with --prefix, and it is very slick. Thanks for that. But I had one problem. At one point in my little app, I have something like this: image_tag(url_for(:action => ''picture'', :id => 1), :size => "160x200") In this scenario,

I''ve looked for DIFF tools for OSX but haven''t found anything good yet. Tried guiffy (http://www.guiffy.com) but it''s very slow and the folder comparison doesn''t indicate a change until you drill down to the level with the difference which kinda defeats the purpose. I''m missing TortoiseSVN and the diff tool that comes with it. Any suggestions for

The speex manual says: "It is recommended to use a frame size in the order of 20 ms (or equal to the codec frame size) and make sure it is easy to perform an FFT of that size (powers of two are better than prime sizes)." What is the impact of using a non-power-of-two frame size here? Since 20 ms of 8000 (or 16000) is not a power of 2, I have to make a choice. It would be most convenient
