First draft for Speex RTP profile - Please send your comments
Hi,
We'd like to announce the first draft for the Speex RTP profile. It was
written essentially by Greg Herlein, with some help from Simon Morlat
and I. We'd like to get some feedback on it before it is sent to the
IETF. Basically this will allow all SIP based VoIP applications using
Speex to inter-operate. For those interested, there's already Simon's

difference with NB and WB
Ronald,
Although you can give Speex data at any sampling rate with any mode,
it's a good idea to use the right mode for whatever rate you have.
Speex is built for speech (not just any audio in general) and is
sensitive to what kind of stuff is going on in certain frequency
ranges. If you tell it your data is at one sampling rate and give
it data with another sampling rate, its idea of

repeated measures aov problem
Hi all,
I have a strange problem and rigth now I can't figure out a
solution.
Trying to calculate an ANOVA with one between subject factor (group)
and one within (hemisphere). My dependent variable is source
localization (data). My N = 25.
My data.frame looks like this:

Re: Speex 1.1 is out
> 1) What should I use for a filter length for speex_echo_state_init()?
Well, it depends on your problem. The filter length represents the
maximum delay of the echo. For acoustic echo, that value is generally
higher than for line echo. You'll need to experiment, but a value around
500 (for 8 kHz) might be a good start.

ogg123 STDIN-control patch
Hello ppl!
I asked some time ago how about adding the option to control ogg123
interactively from command line, similar to mpg123. So I got fed up waiting
and added it myself today. The code initially comes from mpg123, I already
adapted it to work with aviplay and vlc so it's proven and shouldn't introduce
many problems.
The only problems I see now:

Speex encoding/decoding producing garbled audio
Whoops, left this message in my outbox. I managed to fix the problem.
Apparently I was only copying 160 bytes (Frame Size) back into the
audio stream when I should have been copying 320 (chars <-> shorts confused
me there). Hence why I could hear myself yet it was distorted. Half the wav
was missing =)
To answer some of the other questions here, for any insight into what I'm

Updated Speex RTP Internet Draft
Hello,
What's the purpose of the 'sr' sdp parameter ?
The sample rate is already given in the a=rtpmap line ?

I don't really understand how channel Local works. I need that asterisk initiate a call and get some data (DTMF).

Determining length of speex file speech
Hello,
I would like to run a script over a speex file which determines, how
long the speech contained in the speex file is.
So I run through the ogg file, skip the first two ogg _pages_ (speex
header and comment header, both contain IMHO only 1 ogg _packet_), and
then count in any ogg page the number of the ogg _frames_ (which, unless
I used -nframes while encoding, which I did not), and multiply

Speex seek with high precision
Hello everybody,
I'm new to this mailing list so I'm sorry if it's the wrong place to post
this.
I'm developing a Speex player and I need to seek with a precision of
milliseconds. I used liboggz that supposedly does just that, but it never
seeks exactly where it should. For example if I use oggz_seek_units(oggz,
18450, SEEK_SET) result it's 16386 and there is a delay between

Free Fax for Asterisk -- benchfax utility hangs.
I'm trying to install my first channel of FAX. When I run the benchfax
utility, I get to various stages and then the program simply hangs.
There is no excessive CPU utilization and the benchfax program readily
responds to ^C. Sometimes I get fairly far into the test, other times
it hangs almost immediately.
The version of benchfax version I'm using is 1.0.7. I heard tell of a

Speex 1.1 is out
Sounds great!! I will definitely give these new features a try and
let you know how it goes. Every one of them (except for the narrowband
mode) will be really useful to me. I have a few questions after looking
through the source code:
Echo cancellation:
1) What should I use for a filter length for speex_echo_state_init()?
2) I'm assuming I want to call speex_echo_cancel() on each

AEC troubleshooting
First of all, thank you for your input Tim. That is very helpful.
I would love to hear from other people with experience of AEC and Speex.
I guess I have to split my question into to parts now.
1.
Is it a fact that using the windows multimedia API (wave audio) for audio
capture and playback makes it impossible to do echo cancellation with Speex
AEC or other EC method due to inprecise timing?

Calculate the audio duration of a speex file
I am having some trouble calculating the duration of my speex files. I am
writing a speex player in Java and I am using the JSpeex port of the codec
which works but doesn't give me the audio duration which I need to show
progress or implement a scrubber. JSpeex appears to be all but dead but I
don't see any other option for Java playback.
I have tried the method posted here:
