<div dir="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. 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.</div><div><br></div><div>Inserting AEC into the audio chain, it would be similar to: Java (raw audio bits) --> speexdsp AEC --> java --> ffmpeg --> server</div><div><br></div><div>My questions:</div><div><br></div><div>1) Is this possible/feasible?</div><div>2) would AEC return PCM audio at the same sample/bit rate at which it was given?</div><div><br></div><div>Any other examples/information would be appreciated.</div><div><br></div><div>Cheers!</div><div class="gmail_signature"></div>
