Currently I'm having a problem choosing a format for purchased music. When I rip CDs, I usually store them using vorbis 1.1.2 q 7 which I am quite happy with. However, my choices for downloading are pretty much vorbis 1.0.1 and mpc 1.14.
Up until now I have been choosing to go with mpc 1.14 with the braindead preset and then transcoding (I know, not usually a good thing to do) to vorbis using 1.1.2. Do you think it would be better to obtain the file directly using vorbis 1.0.1 q 7 or sticking with my current method. I know vorbis is supposed to be a metric scale, but in practicality I find that it is not (as far as bit rates are concerned). I've done some tests encoding files using 1.0.1 and 1.1.2 and almost always 1.1.2 requires a higher bitrate at q 7.
Any suggestions or opions? vorbis 1.0.1 q 7 or mpc 1.14 braindead transcoded to vorbis 1.1.2 q 7. Thank you very much for any light you can shed on this subject.
Full Version: Old encoder versions and quality
If you already know that transcoding is not a good thing to do, why do you transcode from mpc to vorbis?
In this case, using Vorbis is a better method.
If your goal is to save space, then use Vorbis directly. Instead, use mpc (braindead or, for example, --quality 5).
EDIT: You should use latest versions, of course.

The vorbis AoTuV tuned encoder is the best current version, and is recommended by this forum in it's beta 5 version, IIRC.

Yeah AoTuV is awesome but unfortunately the site is restricted to 1.0.1 for some reason which as I recall is less quality than mpc 1.14 was.
I'm probably going to have to just get a smaller mpc (--xtreme and -q 7 are close average bitrates) and leave it at that. I'm not really sure how much is lost in transcoding at higher bitrates but the few kbps lost using --xtreme will probably make up for it (~210 vs ~224 for vorbis). Thank you very much for the feedback!
Haven't I read somewere that transcoding from MPC is not that bad? Am I wrong?

its still bad, just not nearly as bad as transcoding from say...mp3, it is a subband coder which makes less quantisation noise, but dont quote me on it
