[Speex-dev] delay between speex_echo_capture and speex_echo_playback
Hello, I have been attempting to implement speex aec in an Android HAL without success. In my debugging, I have decided to time a pulse through the system and I am seeing a large delay between passing audio to Audioflinger and getting it back to play. This is causing a delay around 90ms between speex_echo_capture and speex_echo_playback. The documentation states that the async api will insert a 2 frame delay (40ms in this case). To me this seems like my issue. The delay is simply longer than the two frames that the async api is using. Is my thinking correct? Is there anything I can do?
