The idea is that you can first download the ogg, if you later want to make it lossless you'll save few MBs worth of downloading by downloading the recovery file instead of original lossless.
Originally posted by CiTay Do you really think that the mixing, the decoding and the additional mixing are accurate enough to give you a WAV with the same CRC as the original? I have to see proof before i believe that.
Originally posted by Gecko Or another one: you loose your lossy files (hdd crash, accidental deletion...) and think: if only I had not saved those 12% I could still listen to the music today.Perhaps you will be better off using general purpose compression since, as Tom pointed out, you are not necessarily encoding tonal data.
And what makes you so sure that a lossless inverse-mix and a lossy Ogg will amount to the original WAV file? I don't think this works.
Originally posted by madah One thing that this could be very useful for is that you can download a preview mp3/ogg for free (from an artist' page) and then pay to get the recovery file if you want full quality...
Originally posted by mithrandir I fail to see the value in this.
The whole point of this is to not HAVE to 'bite the bullet'.
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 madah Maybe Ogg bitrate-coupling will work this way, or is it only capable of scaling the bitrate down?
Originally posted by Timmy The Turtle Is your modified mpc command line "mppenc --xtreme --nmt 16 --tmn 32" better than the standard --insane ? And if so why didn't you use a modified version of insane. I ask this because your average bitrate seemed to be a lot higher than I get with insane and 0.90s.
