My only means of editing mp3 files (long ones, like 30 or 60 minutes) is to use emacs. I have found, on occasion, that this works fine. It's trial and error, but i find the piece (mp3-encoded) i want to cut out and just cut it out, heedless of frame boundaries. I go to play it back and it works fine.
However, there have been a few times (and this seems to somehow be dependent on the specific mp3 file) when cutting out any part of the beginning of the file causes any subsequent portion to sound odd (some sort of fairly constant/periodic chirpy/warbly/glitchy type artifact) when played back. I almost emailed a question about this because the last time i'd tried to "edit" (extract a portion of) a file this happened to me and i wanted/needed to perform this same type of operation again (i know of no other means). Just before emailing, though, i took a stab using the file i currently wanted to pull something from and it worked fine. Anywhere i started, regardless of what i wanted to cut it, it always played back fine. So i never emailed. Then a couple of days ago with another file i tried the same thing and, again, whenever i cut out any part of a preceding portion of the file (as far as i can tell) subsequent portions would play back oddly. Even to the extent of: if i leave the first meg, cut out the next 15 megs (say) then any part after the cutout part plays back oddly. I tried various permutations on this and on the file where i had any problem, i had every conceivable example of this problem (as far as i tested). When i didn't have the problem, i didn't have it at all. The odd thing is that (as far as i know) both of these files were encoded exactly the same way -- same setup, same encoder, just different audio. Does this make _any_ sense to anyone? And is there any tool available for chopping up mp3 files without decoding (other than emacs, of course)? craig _______________________________________________ mp3encoder mailing list [EMAIL PROTECTED] http://minnie.tuhs.org/mailman/listinfo/mp3encoder
