if i wanted to have mpc files on my computer for home use, but transcore an mp3 version for my car when i want to burn a cd to drive to, is it going to sound like crap going from 1 lossy codec to a different (and slightly primative) lossy codec?
or will it be "ABOUT" as good as just encoded from cd to mp3? (about, meaning no strange artifacts or loss of import audible data)
(asuming i use q6 or q8 or something in mpc... obviously)
i'm trying to get rid of my mp3s, but i can't find a lot of things in lossless... so i figure the next best thing is mpc... but until they make a car player for lossless/mpc i have to make mp3 copies for that...
thanks again!
Full Version: Transcoding mpc to mp3 (for portables)
Transcoding mpc files (--quality 6 of more) to mp3 LAME--alt-preset standard you can't find strange artifacts, I trancode mpc --quality 6 to mp3 LAME -alt preset cbr 192 and --alt-preset standard all the time and I don't found mayor artifacts, the sounds is nice, transparent to me, but I don't make abx tests

what if i wanted to use LAME aps extreme or insane? would it be a waste? or any problems with that?
(i'm not familiar on the theory behind the mpc encoder)
i'm thinking more along the lines of insane for the sake of balancing quality and size on the cd... (i mean, the advantage to mp3 in the car is so you don't need many cds...)
I think that MPC --quality 6 is transparent at 99% of the music that I encoded, transcoding to mp3 is basicallt: decoded to wav and then encoded to mp3. AFAIK the wav file decoded from the mpc is practically the same that the original wav file before to encode to mpc. Then transcoding mpc --quality 6 or up to mp3 --aps or --ape should be transparent, --ape and --api should give more quality that --aps, but to listen in your car I think that is a waste of bits, I recommend that --aps is enough to get high quality (transparent or near transparent)
perfect! Thanks!
I've done many ABX tests and I can't tell MPC -q5 --> MP3 from WAV --> MP3. But that's just me.
And for more info, there's always

I'll save you some time, since even if you did search for "mpc AND transcode AND mp3", it might have taken you a few minutes for you to get your answer, since there are already so many threads on the topic, and many seem to lead nowhere. From the first link (text inside the []'s are my additions):
It's nice to try contributing to or looking for an existing thread on a popular topic, because then the board doesn't have so many zillions of threads on the same topic. Thread-mania makes it harder to find a useful thread in a search, so then more "duplicate" threads show up... which you undoubtedly ran into before posting this new thread.
I'm in the same boat as torok, as far as the ABXing goes. Gecko's got pretty good ears. B)

All the recent problem samples that have been reported, artifact over a broad quality range. The audibility of the artifact will become less if you increase quality of course, but if you listen closely it will still be there even with q7. That q7 cures all artifacts is a myth.
When you transcode from q5 to mp3-aps you will get a few mild artifacts here and there (So that mpc-q5 --> mp3-aps is ABXable from original-wav --> mp3-aps). q6 cures most of them. For use in my portable mpc q5 sourced transcodes are quite sufficient.
Btw, you are not limited to only standard or xtreme. You can use anything in between like --quality 5.3. Make some of your own tests and see where those transcoding artifacts disappear.
[...]
Bottom line: if it [meaning, the original WAV->MPC encode] artifacts at q5 (which is rare), it will artifact at q6. You will not have fewer artifacts by increasing the bitrate. q6 offers better transcodability.

well, i'm an enourmous TOOL... not because i didn't try to search first... but because I dind't use "AND" in between all of the words, thus coming up with NO results...
my apologies... i'm on a bunch of other boards that work differntly, so i didn't think twice about it...
but thank you for all the information/answers... you've definately helped me out... in the future, i'll take the TOOLage down a notch, and use separators in my search queries... lol...
