Invalid mode encountered: corrupted stream?
Hi,
in my application i quite often (not allways) get those two warning:
"Invalid mode encountered: corrupted stream?"
"Invalid wideband mode encountered: corrupted stream?"
The stream is not corrupted but i wish to know what those warning mean to
correct my code.
My encode and decode routines are those (libspeex 1.1.4):
SpeexBits enc_bits, dec_bits;
void *enc_state,

problem with speexdecode.
I compiled speex1.2 on my linux box and they used speexenc to transcode an
16khz 16bit PCM mono wav file into speex. I used quailty 4. When I try and
decode the file with speexdec back into the wav I get an error
unknown nb_cbl request 39 and then a segmentation fault.
Any ideas?

Again, teach me speex AEC please!
Dear all:
I need the help desparately.
The code is attached below.
If you guys don't mind take a look at the code below and see how to fit speex's AEC into it.
Help me look at the #defines, and give me some suggestions on the AEC parameters, I totally have no idea about them.
Feel free to do anything with the code, if it is by any chance valuable.
Any ideas or suggestions or sharing

Echo canceller end up more echo than before.
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

Need some clarifications about "speex_preprocess_run"
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.

Anyone tried to call speex from jni? Need help here!
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

How to use the speex AEC
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?
