Hi All, I am trying to get speex working on the Mac and am running into issues. I got the examples working, but am now trying to make speex, which expects 8000 Hz and 160 samples per buffer (320 bytes per buffer), work with the Mac's built-in audio recording, which uses either 11025, 22050, or 44100 Hz and 1024 samples per buffer (2048 bytes per buffer). I just need to know if

...ne can say if so? P.S. The above situation is almost exactly what happens on my Mac, and would be exacerbated by people with third party sound cards. ------------------------------------------------------------------------ Zack Morris Z Sculpt Entertainment This Space zmorris@zsculpt.com http://www.zsculpt.com For Rent ------------------------------------------------------------------------ If the doors of perception were cleansed, everything would appear to man as it is, infinite. -William Blake, The Marriage of Heaven and Hell

Hi, I tried both the stable and beta versions of the speex source code download on Mac OS 10.4.9. I just do: ./configure make sudo make install Then I added libspeex.a from /usr/local/lib and the headers to my xcode project. My app compiles and I'm able to call all of the speex functions. I copied the example code from the website and tweaked it to include the first 10000 bytes of

...it, so they need to be remedied. Thanxs for writing Ogg Theora, I think it's a wonderful library, just needs some better documentation and examples. I tend to work on the back end of things and realize that getting someone to write concise example code is like herding cats. Zack Morris zmorris at zsculpt.com

Hi, I wanted to let you know that I have just made available the sources to the ogg + vorbis implementation in haXe, which I've been working on for last couple of weeks. The code compiles to an swf file playable in Flash Player 10. A demo of a simple player implementation (latest Flash 10 required): http://people.xiph.org/~arek/pg/hx/test.html and the sources, in a bzr branch, currently

I downloaded and built the Ogg and Vorbis projects and added the frameworks to my project. It just SIGTRAPs before reaching main, in dylib loading code. I then built libvorbis.a, libvorbisenc.a, libvorbisfile.a and added them to my project. Still SIGTRAPs. I built a libogg.a target from scratch in the Ogg project, and added libogg.a, still SIGTRAPs. So I have tried everything I know

Hi All, I've been doing a lot of cross platform work lately, getting Ogg Vorbis to run on Mac and PC, but haven't been able to find a readily available version of libogg and libvorbis for iPhone. I see a macosx target in the SVN trunk but not an iphone one. I found these links with some background: http://lists.xiph.org/pipermail/theora-dev/2008-October/003719.html

Hi All, I have tried using echo cancellation, and I think it doesn't work well, because of how I resample. I take the raw 44100 Hz on my mac and just do a loop averaging every 5.5 samples to 1 sample to get 8018.18 Hz, and feed that to speex in 160 sample buffers. I realize that this introduces some aliasing, and I may try the new speex resampler, but I find it hard to believe that

Believe me; I've "played with" priorities and buffering. Did you just say you have no idea how the Speex residual echo suppressor works? If that is the case, can you tell me where I could get some information about it? -----Original Message----- From: Jean-Marc Valin [mailto:jean-marc.valin@usherbrooke.ca] Sent: Friday, June 29, 2007 7:38 PM To: Coffey, Michael Cc:

Hey everyone, I saw over on the Vorbis-Dev list that they ported Ogg Vorbis over to Flash. Just wondering if this would be possible for Speex, and also if you have considered an iPhone implementation. I know that Apple is really hesitant to anger AT&T, but with Google's Android, VOIP on cell phones is just around the corner. Ironically voice bandwidth is set to go way down

Hey sorry to hijack this thread, but I just remembered a request I wanted to make to the speex devs. I tried using the activity detector, but I just couldn't get it working well. I ended up using my own, where I think it just considered voice on if it passed a certain threshold (I know, pretty primitive). I also tried one that checked for a signal, like if the strongest frequency
