Obviously we should all have backups, but if you only keep the lossy version you can never reconstruct the original. I still think storage is cheap, compared to the cost of producing that audio in the first place. For example: Budget for recording Nevermind by Nirvana at 1991 prices: US $60,000 Disk space required to store Nevermind recording in 44.1KHz 16-bit FLAC format: approx 210MB for 42 minutes Price per megabyte of Nevermind recording in FLAC format: US $286 Price per megabyte of disc space on a 3TB SATA drive at today's prices: US $0.00005 > anyway, everything >= 256kbit mp3 source files sound ok. everything <= > 128k sounds bad. Then perhaps you should try a better codec than MP3 :-) Cheers!
