Hi, my VoIP system uses speex with framesize = 160 samples(20 ms) at 8khz, sending and receiving paquets of 1600 samples(200 ms). When I receive a packet, I buffered it (I have also tried with speex_echo_playback) before sending to the speaker. When I capture from microphone, I fist remove DC offset (I saw in OPAL sources) and then I call speex_echo_cancellation for every one of the 10

? hi all, i am using the Acoustic Echo Cancellation from "Speex 1.1.12 version" in my VOIP application. Is it that the frame length to be chosen should always be 20ms or can i have flexibility in chosing the frame lenght? on what parameters does the frame length choise depends? thank you all, Shri. -------------- next part -------------- An HTML attachment was scrubbed...

While it was a good move from Rails part to escape ERB <%= %> tags by default, it doesn''t seem to happen to Sprockets as well. The strange bit is that according to Sprockets documentation, it would be just a matter of naming your template as .jst.eco to enable Eco: https://github.com/sstephenson/sprockets#javascript-templating-with-ejs-and-eco Then, extracted from Eco

Hello R users: I would like to produce a world map with countries colored according to whether they fall into one of 7 eco-climatic zones. For simplicity, each country is allocated to exactly 1 eco-climatic zone. For this purpose I have looked at the map and mapdata packages, which contain world maps composed of polygons (1 for each country, it seems). Each of the polygons can be referred to by a

Dear Zongshan Li, I'm forwarding this back to r-help ... it's generally best to keep the conversation going in public, so that (a) other people can chime in with ideas and suggestions, (b) your question doesn't get lost if the original respondent doesn't have time to deal with it, (c) the answers are archived for future reference. Your example (I've attached it, hope it

Hi, I am developing real time audio application and I need to cancel echo. First I tried to make simple echo cancellation test application to test if my code will work. I make a call with two SIP phones (one with speakerphone). I dumped the RTP streams via wireshark and dumped it to the PCM 16 audio (8000 samples). 160 samples per 20ms and I used 640samples tail. I try this test data on the

On closer looks and debugging I always end up in speex_echo_cancel function with comment /* Temporary adaption rate if filter is not adapted correctly */ Does this give any clue to the problem? I wonder why it would not find its mirror image as an echo and do echo cancellation? Any insight is appreciated. If you need some more data, tell me. Thanks -Anurag Quoting ac2491@columbia.edu: >

Hi, I tried keeping it for a very long time and put logs there and it always went to not adapting. This is how I initialize speex_echo_cancel SpeexEchoState* _echoState = speex_echo_state_init(160, 320*10); I have 20 msecs of audio with 16bits for a sample. If two frames are identical and are given to speex_echo_cancel for many iterations, should I expect silence. Thanks -Anurag Quoting

Hi Speex Developers, I'm Andrey Zhukov, the developer of PI-CONSULT GMBH company. Building a voip application that uses your libraries, i have found the strange problem with the latest version of Speex Libs. Our application works under win32, and i used before version speex 1.1.12 ( were built from sources). It seems i have resolved the known problem with clock drift of audio cards using

Hi All I am using speex in one of my WinCE project. I have been trying to use speex to perform denoise on the captured audio packet and echo cancellation. Following behavior I have observed while using various options. I would really appreciate if you could help me with the issues I am facing. 1. Denoise: I have written the following to code to perform denoise. //To initialize speex

Hello again, I want to ask a question in my mind by reminding the topic below. Can the reason of failing be that Codec,which plays sound, and Mic are connected the different clock source? If it is because of that, what can I do to cancel the echo? Isn't there any solution for this? Is asynchronus speex functions for this? Best Regards, KAHYA PS: Sorry for my bad english.
