But that's what a jitter buffer will do, eventually - drop a packet. And it's better to drop a silence packet.

This is a common problem. Sound cards run at different clock speeds (but your difference seems kinda high). What I'd suggest is dropping silence packets once in a while. .a -----Original Message----- From: speex-dev-bounces@xiph.org [mailto:speex-dev-bounces@xiph.org] On Behalf Of Shantanu Gramsci Sent: Wednesday, December 21, 2005 2:05 PM To: speex-dev@xiph.org Subject: [Speex-dev] Bitrate

Hello All, I use AGC as one of speex preprocess options in VOIP application. In most cases it works very fine. However, at the very beginning of a call when no one has started talking [ and some times in the middle of calls], AGC makes large noise and it gradually increases. Interestingly, when someone starts talking, from that point it works very well. Is it the normal behaviour? Since

Thanks all for your prompt reply. I agree with Alex. I think jitter buffer will have to drop packets if its input bitrate is higher than it is configured for. I never tried speex jitter buffer. What does it do when input bitrate is higher or lower ? As an alternate solution, I was thinking to play with directsound playrate [using SetFrequency()]. Has anyone used it to solve such problem? Any

Dear all, I need to use echo cancellation in a VOIP application using speex narrowband codec.I am facing some problems with echo cancellation. It will be very helpfull if someone can put some light on the following issues. 1: =================== -- When call is started EC works fine for first few seconds. Bur after a certain period [usually 20 sec or more] it does not work or works very bad

Oh, I forgot to mention one thing. I currently append a few bits of custom information to each speex packet which I fetch out with things like speex_bits_unpack_unsigned(&sjJitter.current_packet, 1); It would be very usefull if the jitter buffer didn't actually decode the packet, but instead returned a pointer to it (or NULL if you should play silence and -1 if you should repeat the

Hi All, I am trying to achieve ACL set in Public folders, I have public namespace in dovecot.conf like this namespace public { separator = / prefix = Public/ location = maildir:/var/mail/public/ subscriptions = no } and now under public folder I have two subfolders .test and .test1 . I have created dovecote-acl under .test so that it can be seen and subscribe. but I can't see

Hi all, I am using rsync v.3.0.7 (protocol v30) on ubuntu 10.04.

Hello all, I am new to speex. Can anyone please mention name/links to open source projects that use speex for echo cancellation [not only codec].

Hi, I use speex1.1.10 [June 10, 2005]in my VoIP application and it works very good for me. But sometimes I get loud metalic noise. Turning off EC, disappears the noise right away. I use EC with denoiser ON, AGC OFF, echo tail 400 ms. Has anyone experienced this? Since Speex1.1.11 has improvement for EC, I tried with the latest release [Speex1.1.12, which has fixed point EC]. But in my test, EC

Hello All, I have built up my email server with exim + dovecot + clamv/spamassasin. I am using exim as LDA(local delivery agent). I was reading about using dovecot as LDA but I couldn't find why should I use it? Now, I am looking expert advice on "Why should I use dovecot LDA" ? Is there any benefit in terms of functionality or performance ? Any advice/suggestion/feedbacks

Shantanu, let's continue here. You first noticed this on a Dell OptiPlex 755. I think it covers all Dell OptiPlex/Latitude/Precision models that are PCIe based with Intel LoM (LAN on motherboard) utilizing the BIOS PXE OROM, based on the similarity of these systems. The symptoms are that PXELINUX requests pxelinux.cfg/<UUID> by TFTP (but it might not strictly be a TFTP issue) when not
