jspeex question
The link is http://www.adobe.com/devnet/rtmp/. TC Message stands for TinCan message. It is 11 bytes long, first byte is message type, three bytes of payload length four bytes of timestamp and three bytes of stream ID.
The first byte of the payload for audio message is the format byte and the rest of the byte is the payload.

jspeex question
FLV contains TC messages? TC message payload contains a format byte and speex frames (up to eight). In the format byte 0xb0 indicates speex. Speex is always 16 kHz, 16 bit, mono.

jspeex question
Thanks for the help folks, but I got this working a couple hours ago. =)
I'm quite please after struggling with it for a few days.
I just needed to take each audio tag from the FLV file and feed the contents
of the tag (except for the first byte) to the jspeex decoder and write the
results to a file.
Jozsef - it is possible to specify 8KHz in the flash client and decode it as
such. Speex

herky-jerky audio
Just an update, and a follow-up question:
I'm making progress on this issue, and will likely have something working
very soon, now that I understand how the jspeex transcoding classes work.
Unfortunately, I will need to make a couple small changes to the jspeex
source code.
My question is - is anybody using jspeex for streaming speex-encoded audio?
It works great for static audio, but seems

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 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);

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.

Is there a document somewhere that describes speex-encoded FLV files?
What is a TC message?
Thanks.

How do I implement Acoustic Echo Cancellation (AEC) using JSpeex(Java Port of Speex)
I read the question:
http://stackoverflow.com/questions/3403152/acoustic-echo-cancellation-in-java/3403198
But my problem is that my project is using Encoding and decoding
mechanism using JSpeex and I am not sure whether I can integrate the
above java code with my project.
So can someone tell me how can I implement Acoustic Echo Cancellation
(AEC) using JSpeex(Java Port of Speex).

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

Need help in speex..
Hi, Vipin,
What you're going to want to do here is convert your 8-bit stereo
samples into 16-bit mono samples and back again when you're done(*).
What you are actually doing here, it sounds like, is feeding 2 8-bit
mono samples into Jspeex, which expects 16-bit mono. So, the
most-significant-byte is in the right channel, and more or less gets
encoded/decoded properly, but the

speed and memory
hello,
i switched to use the encoder.processData() and
encoder.getProcessedData() of jspeex. however it looks to me like a
memory leak ... memory usage is increasing very fast and there is no
visible stop ... after about five minutes java.lang.OutOfMemory occurs.
I think it must be the jspeex component, because before i added jspeex
to my app usage was constant at about 5mb.

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 distortion playback issue
Hi all,
I'm having a playback issue I can't eliminate.
I'm encoding 16khz mono WAV files (voiceover recordings) to speex using
a quality setting of 4.
In any standalone speex player e.g. winamp or using speex frontend etc.
the files play fine, but in a jspeex environment there's a subtle high
pitched beeping type distortion, mostly on the transients.
The sound is similar to
