Now I've opened this can of worms, here's a real-world issue which will
probably never occur again. I have a John Mayall "Blues Breakers With
Eric Clapton" CD [EAN 0042284482721] http://tinyurl.com/plcu65u This CD
contains both mono and stereo tracks which EAC has extracted to all
being stereo. I have separated the tracks into two directories: John
Mayall - 1966 - Blues Breakers With Eric Clapton (Mono), and John Mayall
- 1969 - Blues Breakers With Eric Clapton (Stereo)

I know you're aware I won't be held back by the minutiae, so whether all
the tracks ultimately end up in one directory or two, those faux stereo
tracks will be getting processed at some point. Before I drop them into
Audacity [Tracks - Stereo Track to Mono], I would appreciate your best
practice advice on what to do next.

I'm not sure what you're asking me TBH.

I'd probably use sox to make the tracks into flac files. And add the -c 1
option for the mono examples to get mono flac files. (Use stats at the end
of the command to keep an eye on possible clipping, but it shouldn't
happen.)

FWIW someone in the past found they got clipping with using Audacity to do
a stereo - mono conversion as it added the values before dividing them by
2 to average. But I think they were using fixed point mode. Didn't check
myself as I always use sox for such tasks. I just use audacity for things
like click removal or LP captures.

Just whether it would be advisable to avoid using the Amplify effect in Audacity on my music files.
The '66 Beano Album tracks are now mono.
Thanks.

I'm going with '66 true mono and '69 faux stereo, due to the studio's reluctance to invest in new stereo recording equipment versus the record company's greed to cash-in on the expanding stereo replay market.
Hopefully EAC will have created left and right channels which are effectively the same due to being from a singular mono source.
All a bit academic now. The conversion sounds okay to my ears, on my equipment, in my room. Job done and move on I guess.

Managed to download SoX despite http://sox.sourceforge.net/ currently experiencing problems, "The sourceforge.net website is temporarily in static offline mode. Only a very limited set of project pages are available until the main website returns to service."
http://sourceforge.net/blog/sourcefo...e-restoration/

http://sourceforge.net/ allowed me to search for "SoX" leading me to http://sourceforge.net/directory/os:...updated/?q=SoX and http://sourceforge.net/projects/sox/?source=directory, so thanks, I'll have a play with SoX the next time I need to process files and time allows investigation.

So here we are worrying about whether 16 bits is good enough (I think it
is, just) or whether we should sample at 96kHz or 88.2... and I put our
DAB stereo on today. I thought it sounds a bit off, so I checked. 80kbit
mono. Try another station. Same.

I think I might have to get a net streamer appliance and chuck the radio
away!

Use the radio streams on Freeview. Not entirely brilliant, but a sight
better than DAB.

Alas, less useful as advice in Scotland. :-/

FTA satellite? I don't much use mine, but pretty well every radio station
seems to be up there if you look.

I'm happy enough with the internet streams.

Just that I don't think recommending 'Freeview' for BBC radio is the first
suggestion I'd make. In England it may be fine as they don't lose out to
Alba TV.
