Hi, I try to use Speex codec into Win32 platforms. However, I find the CPU bandwidth usage is very heavy on a Pentium 3 machine. Compare to Microsoft's G723.1 codec, speex 8k is using more than 20% cpu bandwidth. Does anyone know what is the best version of Speex to "beat" the Microsoft's G723.1's on CPU bandwidth usage? Does Speex have MMX-enabled codes? thanks very

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

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. Regards, Matthias --

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.

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

But using the ACM codec I just need to put the speex content into the wave file data chunk and then windows will play it?

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?

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 ---

? is there any speex code in place that may help enable variable speed playback ? or perhaps another open source project has some code for this ? variable speed playback for voice messaging is an attractive feature, that would be well recieved for sure ! thx for any reply, Mark Tom Harper <tharper@sightspeed.com> wrote: At 12:35 PM 10/6/2004, Matthias Granberry wrote: >There is

Are there any caveats when trying to get speex running under PocketPC? I'm under fairly tight bandwidth constraints and would like to avoid going AMR. Is it about as simple as setting up a project and running, or is it a more involved port? -------------- next part -------------- A non-text attachment was scrubbed...

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

Whenever I try to run Half Life under wine it askes the to change my color depth to hicolor. Other appz run in many colors though. Any thoughts???

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

Use the -V option when encoding and you should get bitrates.

Somewhere in the new packet-loss concealment code, there is a bug. I tried encoding a 44100-hz stereo file and it decodes just fine, but if I try it with packet loss, I get a segmentation fault. If you want to see the file, I can put it up somewhere publicly accessible. If someone here can't work on it, I'll be back on my home computer in a few days, so I'll work on it then.

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.
