similar to: cosmetic problems with speex encoder in rc3

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

Hello, I'm new to the list, so if this is an FAQ, please point me to the relevant docs. I'm playing with Theora, to see what kind of quality I can expect (I realise its not for production use yet). I've download the source from CVS, and got it to build, with the example encoder and player. While trying to find something to serve as a good source of input, I decided I'd use a

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'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

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

Greetings, I was on IRC about 7 hours ago and suggested that the FAQ be updated slightly. Rather than sit on my ass and complain I figured I'd ask a few people, and see if the idea was worth the time. Here's what Ive started with: http://www.dimension.net.nz/theora.html I'll be adding to it over the next 24 hours - mostly in the area of Playback and Encoding. Just threw it together

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

? 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

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:

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 ---

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 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

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.
