I like using the Firefox add-on DownThemAll to download stuff in bulk from the web, such as live bluegrass shows from The Internet Archive. I have been playing with the lossless versions of the shows, notably the ".flac" format. Flac is a lossless audio compression algorithm, which means that it should sound identical to the original recording. Mp3 and the such are lossy formats that make an audio file sound worse than the original.Anyway, I was trying to use DownThemAll to nail the .flac files, but the file filters trigger on most of the files, as the word "flac" is in the filename somewhere on ALL of them. I had to play with regular expressions, but you can weed them out by hitting the fast filtering mode and inputting this:
/\.flac$/
It basically means to weed out the files that END WITH .flac.
Nailing a Hit and Run Bluegrass Show as we speak.
I hope this helps somebody else out - this was way frustrating.
