similar to: echo cancellation seg faults

Hi, If I pass the same ref and the echo data to the echo cancellation API, I am expecting silence as output. I get back the original audio data. Is this correct?

Probably the level of your signal is too low and/or you're just not letting it time to adapt.

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

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 Jean, I got the earlier problem fied with correct NN and tail values. But I dont see any echo being cancelled. To the echo cancel API I am giving, audio packets that are being played currently and audio packets that are captured from the mic. Since the audio packets being played came from machine B (as in a normal VoIP call), could this be a potential problem? As the packets being compared

dear all I got this error when I try to use libspeex in visual studio. when I include speex/speex_echo.h, it complains about unresolved external symbol _speex_echo_state_init. And when I include mdf.c into the source, it generates whole bunch of errors. Any idea? thanks so much --------------------Configuration: audio - Win32 Debug-------------------- Compiling... mdf.c C:\Documents and

Hi, I am using Twinkle to call mobile phone but there is too much noise on the mobile user's end. Mobile user's voice is echoed back to user. While on twinkle end everything is fine.

Hi, I am using 1.2beta2 on a C5416 doing narrowband in the decode function I am having a problem with the execution of my program vectoring off to random interrupts that are not used. I have tracked down the error to the highpass function called in nb_decode -very close to the end of the function-context: it is called here: ln 1719 for me if (st->highpass_enabled) highpass(out,

Sir, I am a 4th yr undergraduate student pursuing my BTech in CSE at IIIT Hyderbad, India. I am interested in applying for Xapian in Gsoc 2014.

I had done gone through the information Retrieval and

Hi All. Someone is attacking on my SIP server. There are lot of requests coming in and I am not able to stop it because I am unable to detect the IP address. I used wireshark to capture the packets. Although I am using very strong password for my SIP users but still is there any way to drop these packets and stop this attack. I tried dropping packet after matching some string (most of the

Hi! there are some problems with echo cancellation filter from speex. problem 1: some noises, echo is removed, but sometimes you can hear some noises instead of echo. I was trying with many different parameters for buffer length (40ms and 20ms), filter length (from 100ms to 4s) and echo tail (2 to 5 buffers), but could not find the right setting. problem 2: it happens that the filter

Hi, I am using Microsoft Word Viewer to view documents via wine. CUPS is installed and working perfectly. But when I try to print via Word Viewer, it says no printer found :(. I checked the config file in wine, and its shows that CUPS is present. Kindly let me know how to get it working :) -Regards Anurag __________________________________________________________ Give your Company an email

Hi, I am bring SPEEX up on Analog Device's Blackfin (using Visual DSP++ tool set). The floating point was too slow on this fixed-point processor so I am going for the integer version. The floating point library build was very clean, but when I build with FIXED_POINT defined, the compiler exits when it find this discrepancy in \libspeex\cb_search.c : ".\libspeex\cb_search.c",

Quick and dirty question: for the TDM410P I must use the wctdm24xxp driver? Att Vin?cius Fontes Desenvolvimento Canall Tecnologia em Comunica??es Ltda.

Thanks for alerting me to the new changes. I just tried the latest code from SVN, but unfortunately I still have just about the same results. The estimated echo that gets subtracted from the actual echo is such a small signal that it doesn't really result in any noticeable echo attenuation. I currently have my filter size set to 2 seconds even though the echo in my microphone file is only

I've tried some further debugging to see what mdf is actually doing. Instead of sending: tmp_out = (float)ref[i] - st->y[i+st->frame_size] to the output, I just sent st->y[i+st->frame_size] to see what was being subtracted from the microphone input. When I open this in Audacity, I see a very small signal at about -40dBm. The actual echo in my sample has a power closer to -20dBm.

Hi All, There is an option of starting the recording of call after the call is bridged. [ b option]. Is there any way of running an AGI script only if call is bridged otherwise not.
