SpeexEncoder requires 320 samples to process a Frame, not 160
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.FileOutputStream;

q about jspeex
Hi,
It would appear the the 'pcm2speex.read(frame, 0, frame.length)' is
blocking which means that it is waiting for data from the underlying
inputstream (i.e.AudioInputStream(t.input)). If it could read sufficient
data it would transcode it. If it recieved an EOF, it should do some
zero padding and then transcode it. Are you sure that you are receiving
data from the underlying

Lost ogg sync using jspeex

I am getting lost ogg sync exception when I tried to decompress a speex stream. I am using the following program for both compressing as well as decompressing. I am just planning to test how jspeex works.

JSpeex help
I am not sure if this is right place to ask for help on jspeex or can some one suggest. I have tried on jspeex sourceforge.net page.
I am trying to use Pcm2SpeexAudioInputStream by creating it from tdl which received pcm_signed audio data as follows:
AudioFormat format = new AudioFormat (AudioFormat.Encoding.PCM_SIGNED, 8000, 16, 1, 2, 8000, true);
DataLine.Info targetInfo = new DataLine.Info

JSpeex help
Hi Sanjiv,
There does indeed appear to be some trouble with
the Javasound SPI encoder (the SPI decoder works well).
I am working on it, and hope to have a fix soon. In the
mean time, you can use the encoder outside of
JavaSound, that one works well (see the command line
encoder as example code of how to implement it).
sincerely

Encoding a wave file with a bad header
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(),

JSpeex - Unsupported conversion
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.

JSpeex - Unsupported conversion
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

Wrong WAV AudioFormat
Hi,
I am using vorbis-tools 1.4.0 on Fedora 14 to convert Ogg Vorbis files
to MS WAV format. It seems that ogg123 is encoding the wrong AudioFormat
value. For Uncompressed PCM, the AudioFormat should be 1 but for some
reason, it is being encoded in the WAV file as -1.
This used to work on some prior version of either Fedora or
vorbis-tools. I thought I'd ask in the email list in case

Decode file written from JSpeex using C/C++ API?
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

Please profile this and mail llvmdev regarding passes with
significantly superlinear behavior (e.g. O(n^2)). My understanding is
that these kinds of algorithmic problems are generally considered

unable to call R t-test from Java
Hello,
My colleague and I would like to write Java code that invokes R to do a simple TTest. I've included my sample java code below. I tried various alternatives and am unable to pass a vector to the TTest method. In my investigation, I tried to call other R methods that take vectors and also ran into various degrees of failure. Any insight you can provide or other Web references you

Fetching Warning Messages
Hi,
I am facing one problem of fetching R warning messages in Java Code
using Rserve. It is easier to trap R Error messages by using catching
RSrvException. I came to know one way of fetching R Warning messages, i.e.
using "withCallingHandlers", below is my Java Program, which uses
withCallingHandlers of R :
