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
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

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.

Lost ogg sync using jspeex

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

q about jspeex
Hi,
i have:

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

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

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:

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

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);

Mixing audio
Is There any intension to deal with mixing two or more streams encoded with "speex".
Most voice wise applications (such as conference) need this feature.

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

Real-time JSpeex coding
Hi,
Is real-time possible with the current java-based JSpeex for real-time
full duplex voice communication?
If yes, can you please also provide some details of the Wintel (Windows
on Intel) specifications that you have used to achieve that, and perhaps
the JSpeex encoding/decoding specs used?
Thanks.
Cheers,
Jo Yew
