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.Audio...

...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 - samp...

If I use Speex, 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(),

...length]; while(true) { int n=auin.read(frame, 0, frame.length); System.out.println(""+n+" bytes read."); pout.write(frame); int m=pcm2speex.read(); System.out.println(""+m+" bytes read - 2."); } But, when I run, it waits in auin.read. 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 l...

I'm having difficulty encoding audio using the JSpeex Speex Encoder. My program throws an "Unsupported conversion" exception and I can't figure out why. I've read the related posts and I think I'm doing everything that was recommended. I'm working on Linux, by the way. Any help would be greatly appreciated. Richard Here is my program output: $ java -classpath

This is best answered by the jspeex folks, as it is the interfacing code that you are having problems with. That being said, it looks like, just as it says, you have asked for a conversion it cannot do -- you want it to convert PCM data to speex data at 44.1kHz sample rate -- speex only supports 8kHz in standard operation. It can also support 16kHz (wb) and 32kHz (uwb), but nothing outside of

hello i use the java lib jspeex from http://jspeex.sourceforge.net/ now i use this java code to encode to speex audioInputStream = AudioSystem.getAudioInputStream(srcFile); AudioFormat srcFormat = audioInputStream.getFormat(); AudioFormat targetFormat = new AudioFormat(SpeexEncoding.SPEEX_VBR8 , srcFormat.getSampleRate(), -1, //

...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 pcm16bit...

I'm new to Speex and I'm trying to compress audio using JSpeex in a servlet then play it back on the iPhone. I've managed to get Speex to compile on the iPhone by copying the speex and libspeex folders into XCode. I've read the sample code and the PDF documentation and I have a rough idea how to decode a raw stream. (I'm assuming the sampledec source works with raw speex audio

...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: *"Insuff...
