Hi guys I have tried compiling this attached code, I made all the buffers 320, there is no trace of a 160 buffer, but I get a " SpeexEncoder requires 320 samples to process a Frame, not 160" error. Maybe there's something I'm missing, here's my code: import java.io.IOException; import java.io.FileOutputStream; import java.io.File; import javax.sound.sampled.AudioFormat; import javax.sound.sampled.Audi...

...should be send. i test it this way: pass 2 frames of 20ms with zeros to the encoder, pass 2 frames with rand numbers[white noise as far as i know] and finally use file with voice and silence mixed. all cases it returns 1. please look at the code and point me something i miss or mistake: [code] // SpeexEncoder.cpp #include "SpeexEncoder.h" #include <stdlib.h> #include <stdio.h> #include <windows.h> // // ======== Constructor ======== // // FUNCTION: initializes encoder with narrow or wide band // according to sampling frequency // // PARAMETERS: // - fs - sam...

...JSpeex actually, to compress an otherwise valid wave file with zero lengths in the header would it impact the compression at all? Here's what I'm doing during compression in Java: AudioFormat wavFormat = ais.getFormat(); AudioFormat speexFormat = new AudioFormat(SpeexEncoding.SPEEX_Q5, wavFormat.getSampleRate(), -1, // sample size in bits wavFormat.getChannels(), -1, // frame size -1, // frame rate false); // little endian...

I tried using speexEncoder to manually process data, but I get only noise as compressed data. It took about 200 ms to encode each frame. Also, I am wondering, if preprocessing setting like echo cancellation is possible with this version. How can I check for silence when vad and dtx turned on. Is it possible to control the...

...16bits data to speex, so i can then publish it to a flash client. On rtmp spec is said that is used network byte order, so in a speex frame consisted in more than 1 byte, i guess i have to send it in big endian order. By the source code of jspeex i see that when i pass pcm data as a parameter to SpeexEncoder.processData they use it as little endian and convert it to a float[] and only then the data is encoded to a byte[] of speex samples. I'm only getting noise on the flash client side, and i though it could be an endianess problem, doesn anyone have any suggetion? I'm recording the pcm16bi...

...At this point, the progrm can capture the voice from the microphone to an "ByteArrayOutputStream" object and play it back. I`m willing to add the encode\decode features of Jspeex but I can't make it to work, I`m probably missing somethnig. The code (Part of it) : ----- speexEnc = new SpeexEncoder(); speexEnc.init(0, 5, 8000, 1); //narrrow-band, 5 quallity, 8khz, 1 channel speexEnc.processData(buff, 0, buff.length); // 0 - the offset --- buff is the byte array of the ByteArrayOutputStream (=the voice from the microphone). the exception I get from processData() method is: *"Insuf...
