If the CD is an exact copy of the LP (no compression, EQ etc.), no-one can tell the difference in a proper double-blind ABX test with properly matched levels and if the two are perfectly in sync. The trouble is that most CD "remasters" have been processed to make them sound louder. Some like this, some don't. Which is right? The LP mastering process has severe limitations, so a CD properly remastered from the master tapes with CD in mind could potentially sound "better", or at least closer to what the artist and producer intended.

Here's one of the earlier threads on deNoise: http://forum.audacityteam.org/viewtopic ... 28&t=37275

I follow a workflow very similar to Bill, deNoiseLF -> ClickRepair -> deNoise, except that I process everything as 32-bit WAV. I generally don't enter any metadata until the de-clicked and de-noised files are imported back into Audacity for separating into individual tracks. I never keep any of the intermediate files, so all those huge 32-bit WAVs get deleted after exporting-multiple.

I save the original raw recordings as FLACs. I also export the final audacity project as a single FLAC at the same time that I do the export-multiple (as AAC or MP3). I don't think I'll every be able to tell the difference between uncompressed and a high quality MP3 or AAC, so the final export-multiple is at 256 or 320 kbps.

Like bgravato, I have a DNS-323 with 2 1TB disks in a mirrored configuration. I save my completed project files there (the raw and processed FLACS), and I even keep my iTunes library on the NAS. For mobile use, I can put up to 29 or 30 GB of the iTunes library on my iPhone.
