Originally posted by kritip What happens if you lose all your ogg's (recovery files) in the event of a hard disk faliure, won't the archived files then be of no use because they can't be recovered??

Originally posted by mithrandir To go through this effort of making two files with two separate encoders, then burning one of them to media that can only handle 700MB...
Originally posted by mithrandirIf my original album were destroyed and I could never, ever get another original copy, I probably wouldn't "care" from an audio standpoint. What am I losing? Some wispy fine detail -60dB down in level that my ears can't hear anyway? Oh well, life goes on....
Tonight I encoded Live's A Distance To Here
Originally posted by Gecko since insane stores the whole spectrum, Dibrom pointed out that this would in fact lend itself very well to transcoding while xtreme may do worse...using insane instead of xtreme with your tmn nmt values won't hurt either
Originally posted by RandumSo what you're criticizing isn't the lossy+correction file method of lossless backup, but the idea of any lossless backup at all.
Originally posted by RandumYes, MPC would give essentially transparent results... but how about MPC transcoded to MP3? *I* need to be able to play my files on a hardware player.
Originally posted by Randumyou're critcizing other's archiving methodology based on *your* requirements, rather than theirs. You need to take a long view and realize that the vast majority of people out there think that all of us who spend time on hyrdogenaudio and the like are crazy and wasting our time, since 128kbps is CD quality after all.
Originally posted by mithrandir I actually trust the original pressed media more than burned dye CD-Rs, so I never seriously considered a backup plan.
Originally posted by mithrandir Because these hardware players are devices used in environments that can hardly be considered conducive for audiophile playback.
Originally posted by mithrandir I did investigate this and was a little surprised with what I found. I believe xtreme imposes a fixed lowpass of 19.5KHz but when I decode my xtreme files to WAVs and analyze them in a wave editor I notice that there is often information in the 20KHz+ region...sometimes even in the 21KHz+ region. When I use LAME aps, the frequencies get chopped off by 19KHz all the time, OTOH. Perhaps MPC's lowpass method is different than LAME's.
Originally posted by CiTay Yes, MPC uses a variable lowpass in --xtreme. The lowpassing threshold is adjusted on-the-fly during encoding, depending on the HF energy and psychoacoustic calculations.
Originally posted by meff isn't the bottom line is that:this produces 2 files, one with the whole song encoded in ogg, and another with the .wav difference lossless encoded.therefor, the total encode for backup purposes is smaller than just the full lossless encode, PLUS the added bonus of a easily distributable lossy version.i don't know about you guys, but this seems like it has alot of opportunitys in various areas.if your archiving, the end result is smaller.
Originally posted by JohnV No. This is just it. The result will not be smaller than just one lossless encode.Ogg+lossless difference signal is always bigger than just single full lossless original.
Originally posted by ssamadhi97 I wonder whether there's a possibility to compress the difference file more efficiently... lower amplitude, but higher enthropy, hmmm :confused: ideas, anyone?
