I currently have a java app that uses the ffmpeg api for live streaming. I'm exploring integrating echo cancellation & I'd like to use the speexdsp AEC by mapping a javacpp library to communicate between java & speex. Audio quality is important, using 44.1/16 stereo. Inserting AEC into the audio chain, it would be similar to: Java (raw audio bits) --> speexdsp AEC --> java --> ffmpeg --> server My questions: 1) Is this possible/feasible? 2) would AEC return PCM audio at the same sample/bit rate at which it was given? Any other examples/information would be appreciated. Cheers! --001a11c2d760f9d89c052e2bf306 Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: quoted-printable <div dir=3D"ltr"><div>I've looked at some partial examples and read in = the pdf Manual that the Acoustic Echo Canceller can be used outside of the = speex codec as a preprocessor.=C2=A0 I currently have a java app that uses = the ffmpeg api for live streaming.
