RTP to Speex
First off I just want to thank everybody, especially Jean-Marc, for all
their work on Speex. I have been using the codec in a call recording
application for a couple of years now and it is great. My application is
pretty simple, it just takes wav files created by a phone server, converts
them to speex and makes them available for playback in a custom speex
player. Speex was the perfect format for

newbie qs. how to seek to a point in the Speex file?
Although this actually pertains to JSpeex, I am asking these questions here because they are general questions and also the JSpeex project does not seem to be supported any more.
1) Can the duration of the clip be stored in it? Page 24 here
http://www.speex.org/docs/manual/speex-manual.pdf describes the format,
but I could not see where the duration of the clip is stored.
2)

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 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.

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.
is it possible

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,

newbie qs - can one implement speex for Google Android?
I recommended in a bug report that the new mobile platform - Android should use speex and it was accepted. I was wondering if I can use it as a 3rd party library even now. Can someone please tell me how? The JSpeex project has had no activity for almost 3 years and questions are unanswered.

Encoding/Decoding doubts
Flash player encodes speex at 16 kHz, mono, 16 bit. Fields in the format byte should be ignored if the format is speex. You can set the quality by Microphone.encodeQuality (default 6). You can also set the number of speex frames per tc message using Microphone.framesPerPacket.
Flash player can only decode speex at 16 kHz, so make sure you have the proper sample rate.

Speex play back
I am a Java developer. I represent a small company writing a audio

have been using the software found at the main SPEEX site and looking
for API's we can use there. We are looking for a Java based SPEEX API
that allows us the following playback functionality:

frame size
hello,
i have a simple question about speex frame size.
i work with jspeex - but i think it's speex generic, the question i have.
can i use any frame size i want? or does the size have be in a certain
ratio to other numbers? and what does the frame size in the decoder
mean? encoded or decoded packet frame size?
how much data can i hand to the encoder to encode?
if i hand i.e. 400 bytes to

using speex in C#
You could compile Speex as a DLL (see libspeex_dynamic.dsp) and use PInvoke.
http://en.wikipedia.org/wiki/PInvoke
Note that Speex will still be executing as unmanaged code and your program
will have the added dependency of the native Speex DLL.
It appears that someone created a "Speex.NET" based on JSpeex, but I
didn't find any useful info on it. You may want to search for this

Even if they included Speex support, the Android media API is very
limited, as it can only access audio from a file or an HTTP URL. I

transcoding G.711 (u-law) to Speex
Hi folks.
The jspeex library has classes for converting speex to pcm and
vice-versa. I also
have other code that converts from G.711 to pcm (and vice-versa).
I want to transcode G.711 to speex, using an input stream. Can I
accomplish this
in one step, or must I go G.711 -> PCM -> Speex? If possible in one
step, is there
some example code I could look at for reference?
Thanks!
