The BBC is currently testing a lossless stream of Radio 3 in flac format. The problem is how can this be captured? The obvious choice would be ffmpeg and there is protracted discussion here

Not easy it subjunctively would seem!!

Now successfully captured the BBC lossless stream to file using latest version of i-sound for windows 7/10 - after initial teething troubles. It appears that the BBC will be broadcasting the entire Proms this year in lossless FLAC format for the first time which means that what you hear on line is exactly as it left the studio.

Clever innit!!!

Well I hope it works better than it did for me. I saw that on usenet and hit all the problems they identified - it wouldn't play in Firefox, VLC, or even ffmpeg. The mime-type was arguably wrong (reminded me of trying to get realplayer streams like Britfolk working on Linux). But I learned a lot!

I'll try to help, first of all you must have latest version of Firefox - v53, and I seem to be running a 32bit version on my 64bit PC! Cheapest capture software is Audacity. Now you need to eliminate the missing "stereo mix" problem first, so set left button under mic icon to Windows WASAPI (don't ask!) then both recording and playback device to speakers. Audacity will then record the FLAC stream and you can export the file as FLAC.

I use i-sound for Windows 7/10 which I paid for but does the job very well.

Yes, I saw how to fix it - I just wasn't sufficiently motivated. I'll try it again when I get Fx53 - it wasn't in the SuSE-Moz repo yesterday. (For various reasons I don't want Moz's own builds.)

I shall listen to the proms on DAB. Yes, I know - but I'm too old to notice - and the rooftop VHF aerial blew down. More importantly I now have a couple of nice Pure receivers with separate stereo speakers off ebay.

Well, you can always do the kludgy old thing of using an audio program like Audacity or Wiretap Pro to "listen" to the stream and record it!

It's the recording side that I'm more interested in, and would like to be able to record the lossless stream using ffmpeg which will not process the digital audio in any way without being so commanded! I would like to know if the Audacity FLAC output is identical ti the FLAC input.

When I looked at that thread ffmpeg needed an upstream patch - I would have had to do that and recompile it myself. Presumably that patch will arrive in the Packman repos eventually. I'll refresh Packman and try it later. If not you'll have to follow ffmpeg bugzilla, or whatever. Or ask on the NG.

The_stream plays with Firefox developer edition (54a). No luck with updated ffmpeg.

I'm hoping to catch the Tinariwen Concert during World on 3 at 11pm this evening, I'll record a safety copy from the HLS stream as well on my spare PC.
