RE: Radio now aac rather than mp3
Please do bear in mind though that (from my own empirical comparisons) it seems the iPlayer just TRANScodes the original AAC audio to MP3, it's not encoded fresh from the original source audio. Hi Could you expand on the difference between the original source the original AAC. I thought they were the same thing. When I say original source, I mean the original sound from source that the BBC are using to do the main encodes. As far as I'm aware, they use the same raw source feed as they send on to Sky Digital, Freeview, Freesat etc (there was some discussion of this on the BBC Radio 3 HD Sound thread a while back). From this, they also encode the iPlayer AAC streams for Listen Again. The MP3 sounds like it's a second generation encode - i.e., it's being TRANScoded from the main AAC file - and not being freshly encoded from the raw source audio. If it is actually being encoded from the same uncompressed feed that's being used for everything else, something is very, VERY wrong with the codec configuration. Martin Deutsch who used to frequent the BBC Backstage mailing list worked for Siemens IIRC, he had access to some of the backend stuff and video/audio archives, he may know if someone involved with the iPlayer team isn't already lurking on this list :-) I've also discussed this on the BBC Backstage list recently and provided samples, but that conversation thread's dead for the moment (it really needs some input from people working on the iPlayer team). ___ get_iplayer mailing list get_iplayer@lists.infradead.org http://lists.infradead.org/mailman/listinfo/get_iplayer
