There's software that lets you record streaming audio from the internet and save it as wav or mp3 files. I use Total Recorder - standard edition. It works great and isn't too expensive either. That would be the next best thing to downloading the wav or mp3 files.
why download though?there's crap quality sonatas out there.i haven't found a selection where i can dl a high quality/ excellent performance of beethoven sonatas.
Donjuan, I have a subscription to the Classical archives, so I can download the live recordings. I think It would be Ok to send it to you via e-mail. I'm sure no one would know...It may take a while to download via E-mail though... Let me know if you're interested...-Tony-
