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

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

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

Believe me; I've "played with" priorities and buffering. Did you just say you have no idea how the Speex residual echo suppressor works?

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

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

We are a very small company and moved from WinTel environment to Linux. Killed the WinTel file/print server and implemented SAMBA om Red Hat 7.2. I have some users that need to print to a RICOH Aficio 4106 printer. When I go through the sequence to add printer ...... it appears to install, but the people cannot print. Can anyone walk me through steps as I am novice...... and I do not want to go

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,

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

Dear R community, I wrote and someone else helped me type a 5-page R-info in Chinese, covering the most basic information on how to get and install and start using R on Wintel PC. This could serve those not fluent in/intimidated by English but want to start using R. (I met a lot of those in China) <http://www.ms.uky.edu/~mai/ZhongWen.htm> also a MSword version of the same (may print

All, Can anyone confirm that Samba/Solaris will integrate with TSM (Tivoli Storage Manager) when deployed into a Wintel client environment. ie. Solaris/Samba as a TSM client - we need to be sure that the ACL's will be maintained correctly via a TSM backup/restore (full or partial) Or confirm this does not work, which is not what we want to hear - but the truth will suffice. Many thanks,

Hi, everyone, I was downloading the rm0641b.zip etc. (thanks to Guido Masarotto and Brian Ripley) I noticed rw0641sp.zip there, which do not seem mentioned in the News file. My guess is that it is not a binary file? Is is a source patch file(?) for compiling on Wintel PC?

Previously I've been using a laptop with an "Aptio Setup Utility...2015" to "Disable UEFI Boot" and allow a USBstik with partition1 having: /boot/isolinux/isolinux.bin , isolinux.cfg , menu.c32...etc. to boot 64bit TinyCore. Now this newer laptop has: "Aptio Setup Utility...2018" which is completely different from the 2015 version. I fail to boot linux from

We migrated our entire domain over to a samba3 domain, now I would like to apply a few policies to the network. I've been reading a few migration papers, most mention about a .POL file which is created upon exporting policy keys on a wintel machine. Using gpedit I don't see an export option. What tool should I use for this? greg

Hi All, We are using samba with an Active Directory Server running on windows 2000. Our wintel administrators will upgrade the Active Directory Server to Windows 2003. What will be the consequences on our current samba servers ? Regards, Beno?t.

Hi, Is real-time possible with the current java-based JSpeex for real-time full duplex voice communication? If yes, can you please also provide some details of the Wintel (Windows on Intel) specifications that you have used to achieve that, and perhaps the JSpeex encoding/decoding specs used? Thanks.

Everyone, One of our developers was kind enough to insert some bug checking into the mod_auth_pam and mod_auth_sys_group so that we could see a little more of what was going on with our authentication failures. Here is what we just saw. Two of our users NA\connelmp and NA\guminssa both started getting messages that they were not part of the required group. Here is the log for

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,
