Hi To continue the interesting streamTranscode thread but in a slightly different direction, I have a user station that would like to send us a 64kbps AAC stream and have us transcode that to 64kbps MP3 and 32kbps AAC - is this possible? Points to consider: a) we would be happy to go with another permutation such as: she sends us 64kbps MP3 and we convert that to 64kbps AAC and 32kbps ACC. b) this AAC patch is undoubtedly going to be useful: http://www.brain4free.org/wiki/doku.php/blog:streamtranscoderv3_linux_aac_patch However I am trying to install on a Fedora server and the repositories mentioned in the above how-to are for Debian. I'm having difficulty tracking down all the relevant Fedora repos for some of these components: libogg0 libogg-dev libvorbis0a libvorbis-dev liblame0 liblame-dev libfaac0 libfaac-dev libfaad0 libfaad-dev libmad0 libmad0-dev libflac8 libflac-dev automake libtool Ideally I think I'd like to be pointed towards a Fedora repo equivalent to the Debian multimedia one in the example above. A solution might be for me to create a fresh Debian [virtual] machine and go with that - but I'd much prefer to stick with a Fedora/Centos based platform. Any pointers would be much appreciated and thanks in advance. Bests Chip

Take a look at sox, and see if that will be of any use to you? http://sox.sourceforge.net/ Welcome to the home of SoX, the Swiss Army knife of sound processing programs. SoX is a cross-platform (Windows, Linux, MacOS X, etc.) command line utility that can convert various formats of computer audio files in to other formats. It can also apply various effects to these sound files, and, as an added bonus, SoX can play and record audio files on most platforms. The screen-shot to the right shows an example of SoX first being used to process some audio, then being used to play some audio files. For the list of all file formats, device drivers, and effects supported in the latest release, click here. To see the complete set of SoX documentation, click here. NB. I had to compile the package myself on Centos 5.6, as the default installation package did not have mp3 support included.

And SoX has its own active mailing list so when I cannot get the application to install I can take my questions there :o) If it all works, I'll report the good news back here. Nice one! Chip

When I run into trouble I'll message you off-list and maybe you can help ;o) Cheers Chip
