This page has lots of useful links related to Audio Restoration and information on collecting Vinyl and 78rpm Records as well as useful links to my own areas of interest.
If you're collecting records - why not have them restored to CD standard by using the specialised services on this site?

CDR-Recordable FAQ
Absolutely everything you wanted to know about CDs' and were afraid to ask. Excellent site of Andy McFaddens covering every aspect of CDR including vinyl and tape transfer.

Windows Media Player Classic
Looks like the old style Windows Media Player, but isn't. So if you can do without the fancy do-nowts, give it a go. It won't keep annoying you either will just play whatever you throw at it, with the right choice of codecs and it's FREE!

Audacity
Nice FREE Audio Editor if you want to dabble in Audio Restoration. I t has everything you need to get you started, including software simulation of record equalisation curves, noise reduction and click removal. I don't use it, but have played with it and must say I'm impressed, especially for the price. Congrats to all the people involved.

Roger Wilmuts Home Page
I stumbled across Rogers site whilst looking for information regarding the equalisation curves of 78rpm Records. Glad I did, have a look at this site, it's full of information relating to Artists and Musicians of the late 19th and early 20th century with lots of clips to listen to from Music Hall to Operatic Arias. Thing that struck me was how these guys and gals managed to produce anything vaguely entertaining given the limited technology available. Unlike nowadays where we have all the technology but seem to struggle using it, maybe it's down to talent?

Heebie Jeebies
Probably the best fifties Radio Show on the Net, from Stads Radio Helmond in Holland. Large archive of passed Shows which can now be downloaded in Hi-Fi MP3 format. All the Shows are backed up with detailed Playlists, which of course is very important for the Collectors of Rock n' Roll, Rockabilly, Rhythm & Blues and Doowop. If like me you can't stop, keep rockin' with Jos Wouters.
