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

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?

echo cancellation seg faults
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

echo cancellation seg faults
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: >

echo cancellation seg faults
Hi, For my VoIP application machine A sends speex encoded audio of to machine B and vice versa at. Data is captured in PCM 8Khz, 16 bit and then encoded using speex 1.1.12 The packet A played and the packet A captured through mic are the input to speex echo canceller. So I am trying to remove traces of packet A played from the captured data. I have followed example testecho.c All I hear is some

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
