RE: BBC R3 Lossless Stream
Congratulations to Cebolla for a really thorough test of the binaural stream, with good results.

For owners of Linn DS and DSM devices, I can report similarly good news. The latest beta release of the Davaar firmware (4.58.181) fixes the problem where transcoded WAV streams would only play for a maximum of 2GB (just over two hours in WAV24). Streams now play to the maximum of 4GB. For information, the stream.transcode property I am using is

flac:wav24-0gb, mp3:wav24-0gb, aac:wav24-0gb

Otherwise, MinimServer is set up as per Simon's instructions in post #12 of this thread. For those who haven't tried it, the sound quality of the [R3DASH] stream transcoded to WAV24 is very definitely worth a listen.

RE: BBC R3 Lossless Stream
Version 0.7.1 of the protoype is now available for testing. If you are using an earlier version of the prototype, please update to 0.7.1 by doing the following:

1) In the Packages tab of the Properties window, type the following in the 'Other package' field: minimstreamer-0.7.1

2) Click Install and follow the prompts to install the package

3) When installation is complete, click Relaunch

If you haven't yet installed the prototype, see the full installation instructions in post 12.

This version adds support for the MPEG-DASH AAC 320k experimental binaural stream and the MPEG-DASH AAC 320k standard Radio 3 stream. These are repackaged by MinimStreamer as AAC/ADTS, so transcoding isn't required to make the stream playable but can be used if desired.

Here is a .m3u playlist that is suitable for testing all the streams:
Code:
#EXTM3U
#EXTINF:-1,[R3DASH;aac] BBC Radio 3 DASH

#EXTINF:-1,[R3FLAC;flac] BBC Radio 3 FLAC
http://vs-dash-ww-rd-live.bbcfmt.hs.llnwd.net/al/lossless/client_manifest.mpd
#EXTINF:-1,[R3BIN;aac] BBC Radio 3 binaural

RE: BBC R3 Lossless Stream
Thank you so much, once again, Simon. All installed and working here.

I haven't been able to test the R3BIN stream yet, but my first impression is that R3DASH sounds a little clearer and fuller than the standard AAC stream, while the R3FLAC stream is noticeably better and fuller than the R3DASH stream; all three are transcoded to WAV24 in my system.

RE: BBC R3 Lossless Stream
I am inclined to agree about R3DASH sounding a bit better than the HLS stream (not sure which is considered "standard" by the BBC now). I suppose it is possible that the BBC is using a different AAC codec for the MPEG-DASH stream.

An interesting benefit of using the R3DASH stream is that the stream can be paused for up to 3 hours. I don't know what the pause limit is for the HLS stream. For the FLAC stream, it is 10 minutes.

Simon,

I have installed the new version - many thanks once again. I processed some other updates yesterday and that seemed to stop things from working but I found the post re the .1 version and everything is back now - excellent.

I assume this will at some point be rolled into the official release but is that the case? Or is this simply to be available as a prototype feature.
