Hi Robert, Icecast itself doesn't do any resampling of audio streams it receives. One would likely craft a solution that listens to the original stream and re-encodes on the fly, providing those alternate bitrate streams back to Icecast. I've heard people doing this with liquidsoap and other source clients, and a bit of server-side magic. Some quick Googling provided me with this link that will likely explain more: https://stackoverflow.com/questions/31456998/how-to-reencode-stream-in-fly-and-translate#31457695 HTH, Jordan Erickson On 09/04/2017 11:37 PM, Robert Jeffares wrote:> I have an external aac+ source mounted on an Icecast2 server. > The source can deliver only one stream. > I want to relay the stream in a smaller format as we have severe > bandwidth limitations at this site. > Is this possible in Icecast2? > > regards > Robert > > Capitol FM Te Puke > _______________________________________________ > Icecast mailing list > Icecast at xiph.org > http://lists.xiph.org/mailman/listinfo/icecast
Hi guys, There's a transcoding example using liquidsoap in our cookbook here: http://liquidsoap.fm/doc-1.3.2/cookbook.html Hope that helps!

Also you must keep in mind that processing live audio consumes many resources of CPU. Maybe you should compile avconv with aac+ support enabled ?? I suppose all this is similar with *ffmpeg*.
