DEC 40th anniversary CD

Your best bet with those is probably to compress them as "flac" files (Free Lossless Audio Codec). You can go from WAV to FLAC and back again, compare the audio data from the WAV with the decompressed file, and they'll be bit-for-bit identical. Compression isn't as good as the lossy formats (and if you're going to use one of those, please make it Ogg Vorbis, bitrate-for-bitrate the quality is far better than MP3) but if you're after archiving, it's a better choice than keeping WAV files around. For the ISOFS bit, good old "dd" works a treat. Or perhaps "readcd". If you want to make an exact copy of the disc, you're going to need something like cdrdao to read and image the disc and create a "cuesheet" (which basically tells the authoring software what's on each track and allows you to use a CD recorder to make a near-identical copy). -- Phil. philpem at philpem.me.uk http://www.philpem.me.uk/
