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

Lost ogg sync using jspeex
Hi
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.

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

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 "

Maybe there's something I'm missing, here's my code:

Getting a Side band error when decoding with Jspeex
Hi.,
I am trying to implement speex. Currently i am capturIng sound and encoding it using Pcm2SpeexAudioInputStream. I am feeding bytes from this stream to Speex2PcmAudioInputStream and trying to read decoded bytes. But here the decoder is giving me an error "saying sideband error" and values after it vary with every message.
I donno the reason for this, but I guess it is because

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

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

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.

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(),

speed and memory
Hi Ulrich,
I've never had any OutOfMEmoryExceptions in my tests, and I think
I've been rather thourough, although probably much more thourought
testing narrowband than wideband. Having said this, it is very hard to
get memory leaks in java, so I am sceptical about that. That memory
might not be used optimally is more likely the case. More often then not
reducing memory use

Speex (in ios) really poor quality (and robotic) sound
Hi everyone,
I'm trying to encode/decode with speex, when I do not, the audio is loud and clear, but when I encode/decode to test audio quality, I get a really poor audio quality and a robotic sound.
Here's my init audio method :
#define AUDIO_QUALITY 10
- (void) initAudio {
try {
//SPEEX CONFIG
speex_bits_init(&bits_in);
