mp32ogg

mp32ogg is a Perl script to convert MP3 files into Ogg Vorbis format. It is able to read ID3 tags from MP3 files and correctly tag the Ogg files, as well as optionally rename them based on those tags.

    Release Notes: mp32ogg now uses the more popular format for comment tagging. This release adds support for Winamp genres, and fixes the license in the output. It also now does a check to make sure the ogg isn't corrupt (at least as far as it can tell). The biggest change is the new quality-setting code in oggenc that is now used instead of the the old bitrate code.

      Release Notes: Special characters in filenames and in the ID3 info are now properly escaped. The perl module String::ShellQuote is now required.

        Release Notes: This release is under the Artistic License, tags year and genre information, and also tags oggs with a special "transcoded" tag per request of the Ogg/Vorbis team.

          Release Notes: A typo bug has been fixed. The artist will probably be wrong for anything converted with 0.8.

            Release Notes: This version was fixed to work with oggenc 1.0RC2.

            There is an option to only convert mp3 with a bitrate more or equal than 192kbps?

            I'm not sure I rather want oggs. The quality per size is

            better, but it takes longer to seek.

            True that this will degrade quality, but if you're
            going for similar bitrates, and the MP3 is at
            CD'ish quality, I doubt you'll notice a difference
            (unless you're making low-bitrate Vorbis files.)
            I've not used this script, but rather just done
            the conversion from shell; choosing an average
            bitrate of 128kbps for a Vorbis track, and
            converting from a good MP3 yielded audio files
            that sounded, IMHO, as good as the MP3.

            Since converting from MP3 to Ogg is going to reduce the quality even further, could you please add a disclaimer to the program? Many people don't know this, and when I go to grab an Ogg file from somewhere, I don't want to end up with some crappy sounding audio file.

            Without the disclaimer, you're basically on par with Xing, releasing an encoding program which produces crap output and making the overall quality of what's available go completely downhill. I'm not ripping on your app at all, but uneducated users need to know that this WILL reduce quality.

            Not many people will be willing to sacrifice their
            music for an ideal :-)
            I think moving to ogg will take a lot of
            re-ripping.. but it'll happen - it just needs more
            media attention. Specially in the windows world
            (more users = more ripping = more encoding).

            [no offense intended]
