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:

Millions of ordinary people have systems that do not meet your stringent specifications. It does not matter what OS you or I use.

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 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,

Since you asked for comments... Personally, I'm disappointed to see Speex moving to Git from Subversion. I had just recently learned how easy it is to track progress of Speex using TortoiseSvn. That being said, I'm sure Jean-Marc knows best what the issues may be. How many people are expected to commit on this project this year? -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

wow! i must say vorbis deprecates mp3! lol. although, i had to use the "OSS/3d for XMMS" plugin on my sblive value w/ 4 point sound to get a proper base. On my other box with a diff card, bass is just fine. however, are there any h/w players for vorbis files? the faq only states one manufacturer called iObjects but i see no portable players! Basically, i want to player vorbis files

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

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

Hi all, I'm running R version 2.9.2 on a PC. I'm having a problem with a loop, and have tried using an if statement within to fix it, but to no avail. Any advice would be appreciated. Here is my code: ***************************************************** eblest <- function(i,dir, sterr, weight, aux) { n <- nrow(dir) Y <- as.matrix(dir[,i], ncol=1) sigma2ei <-

I need to calculate the probability that a sample quantile will exceed a threshold given the size of the iid sample and the parameters describing the distribution of each observation (normal, in my case). I can compute the probability with brute force simulation: simulate a size N sample, apply R's quantile() function on it, compare it to the threshold, replicate this MANY times, and count the

I''m a ferret newbie, so hopefully I''m missing something simple :) I am using ferret to index data about 36,000 products from a MySQL database. The index has one document for each product, with these important fields: id: the id (unique) of the product record in the database content: a concatenation of several bits of information from the product and associated records I

Dear fellow Wine users, It was to my recent delight that I found that EndNote 3 will work usably under Wine. However, it does seem to display a slightly odd problem when certain keys are pressed. In essence, the problem seems to be that certain keys, when pressed, generate two keystrokes. So for example, pressing RETURN moves down two lines, pressing BACKSPACE deletes two characters, pressing

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

Do you have specific plans for producing a stable release of version 1.2? I work for a company that would like to use speex AEC in a product. I think my bosses would be concerned about using a library that is labeled as "beta" and "unstable." In the spirit of cooperation, I would be willing to assist the effort in any way that I am able. Thanks Again
