Hello All I'm accessing speex via jni, I have successfully decoded and encoded data and capture and play it back in java. Now my challenge is speex's echo canceller. My capture and playback are not synchronized, so i got to use the method from 1.2beta2 right? What's the proper way to fit speex_echo_capture() and speex_echo_playback() into the following procedures, assuming they were

Perhaps that's because I have some problem understanding the documentation, or dunno how to fine tune it. I tried to use the echo canceller to cancel out echo in case it is present, but when I tried it, it gives me echo even there is no echo at all, and the echo is more serious if there is echo present. I'm using speex with JNI, I shall give more details if needed. But i just want to

Simple questions:1. when this method is called for each frame, do I have to call them twice for both the encode process and the decode process?2. does preprocessor do preprocessing on raw PCM data or on encoded speex data? I need to clarify this because i want to know when should I call this function, before the encoding process (i.e. preprocess the pcm data) or after the encoding process (i.e.

Hello folks. I am using speex through jni. I have no problem doing encoding and decoding but I would like to use the preprocessor feature. The problem is my JVM always crash when speex_preprocess_run() is invoked. I cannot give conclusion that it is this function that caused the error because I checked the error log and there is no trace to it. However, if I commented out this line, everything

I would like to add AEC to my program. Since the nature of my program is such that its playback and recording are asynchronous. I have no idea whether the testecho.c example will work for me. Anyone here has experience with the AEC in async mode? YUN TAO
