Sir, Sorry, I can not return your email immediately. I am out of office from May 18 to June 6, 2006. thanks for your patience, Jay Huang

I know speex is not supposed to do a great job compressing music, but I've noticed that the new VBR code chokes completely when you try to compress horns. I've placed a particularly offensive example up at http://www.utdallas.edu/~matthias/ . Take a look at a-16m*{ogg,spx}. a.ogg is the first minute of an ogg created from the source media (in 44khz stereo). The rest have been mixed down

Is there any way to access only the narrowband portion of a wideband stream? I'd like to be able to encode the audio only once, but allow members in a conference to have some rough selection of bandwidth, and allow them to move to a lower-bitrate stream if there is a need to do so.

I am eager to begin using speex for downloadable audio on my church's website - but first a good win32 player is needed given that windows has a 94% domination... Are there any plans for an up-to-date speex player for windows? (that winamp plugin is hopelessly old) Building this into zinf (fmr. freeamp) might be an option, but their code is one big mess. --- >8 ---- List archives:

Has anyone written a wrapper to use with .NET for the speex Win32 library? I had started to work on it but thought best to ask first. :) Thanks, Jessica <p>--- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'speex-dev-request@xiph.org' containing only the word

This was also our experience porting the Tremor vorbis decoder to a TI dsp. The vendor toolchain is useless; someone really needs to pay cygnus to port gcc. -r ---

I'm going to use speex to compress sound that was record from a sound board. What container should I use so it will be able to play in some sound player available for windows, ogg or wave? If I choose to use wav container I simple have to put the speex stream into the data chunk of the wave file? I heard that there is a codec to put speex in a wav file so it can be played in windows media

Hi all, I want to get the following functionality: define one extension as a virtual fax machine. Every fax redirected to that extension to be converted in a picture file (bmp/jpg/gif or something else) and then attached to an email and send to an e-mail address. Are you aware of a linux based application who does something like this and can be installed on the same computer as Asterisk? Another

Hi, Just to let you know that Speex 1.0 RC3 is out. It should be the last RC until 1.0 is released (tentative release date is March 16th). Please give RC3 a try and report bugs so they can be fixed before 1.0. As usual, download from http://www.speex.org/download.html Jean-Marc -- Jean-Marc Valin, M.Sc.A.

I've been given the task to hunt down a codec that out solar car team can use to transmit and receive data over a radio link between a chase car and the solar car its self. As of now I do not know the exact specifications of the internal hardware of the car, what I do know is they are looking at transmitting across a 2400baud connection, the unit in the car is homemade from our labs here.

Take a look at this: peexenc --vbr -V --quality 4 audiodump.wav a.spx Encoding 32000 Hz audio using ultra-wideband (sub-band CELP) mode (stereo) Bitrate is use: 22400 bps (average -1268444817 bps) I'll take a look at what the problem is later today or tomorrow, but if anyone beats me to the bug, let me know before I spend too much cscope time playing with it.

I'm trying to get asterisk working w/ packet8 (incoming and outgoing) and a dta310 so I can have more control over voicemail. I've looked at the data stream coming from the dta310 and from packet8, but I haven't managed to get the phone to actually place invites through asterisk. On the asterisk end with chan_oss.so, I can make it dial and I hear ringing and the first second of

It looks like I'll need to go further into the guts of speex to do this. I do, however, see some lines in nb_celp.c/nb_decode() that look interesting. I guess I'll play with it. I doubt that it will be terribly clean, though. Jean-Marc: Take a look at line 1195 in nb_celp.c (CVS). It reads "speex_warning ("More than to wideband layers found: corrupted

Hi everyone, I'm currently attempting to move Speex development over to Git. Because Git is distributed, I means that anyone would be able to do development and commits without having to get write access (and I can just pull from them). There are of course other advantages, like sane handling of branches and tags, local history, ... Now, one of the disadvantages is that Git currently

Hey, thanks for sharing this information. If this is true, it could explain some intermittent problems I've had, since I do encoding and decoding in separate threads. I assumed that Speex was thread-safe because there doesn't seem to be a connection between the encoder and decoder, and the encoder and decoder require separate states for different streams. I'm curious to know

Not a big deal, but the "<http://xiph.org/svn.html>Subversion Access" link on http://www.speex.org/download.html page should probably point to: http://www.xiph.org/svn/ rather than: http://xiph.org/svn.html Tom ______________________________________________ Tom Harper Lead Software Engineer SightSpeed - <http://www.sightspeed.com/>http://www.sightspeed.com/ 918 Parker

Jean-Marc, So I saw in the latest code that the vad in the preprocessor is gone/going to be re-written. Is there a plan as far as this goes? Just wondering as the current one seems to work pretty well. Thanks!

Hi, So I got a crash on the following code: k1=SUBMODE(lpc_enh_k1); k2=SUBMODE(lpc_enh_k2); which in the newer codebase is: bw_lpc(SUBMODE(lpc_enh_k1), st->interp_qlpc, awk1, st->lpcSize); bw_lpc(SUBMODE(lpc_enh_k2), st->interp_qlpc, awk2, st->lpcSize); I am not sure if the newer code will have the same issue but the following check is
