Efficiently edit many MP3 files using a combination of GUI operations and scripting.

  Plenty of people still use mp3 files. It’s not representative of the average person, although the average person isn’t going to be using this tool, but the large(est?) music tracker still accepts uploads in flac and mp3 format, scene releases are in flac or mp3. For a broader example, when people want to rip music from YouTube, they google stuff like “youtube to mp3” and if you google “download youtube music” top results names like “convert youtube to mp3” and the results not including “mp3” in the title offer downloads in mp3 format. It may not be technically the best format, but my parents know what an mp3 is, they have no idea what aac is.

    In a context of "converting youtube into mp3", "technically not the best format" is an understatement for what most likely is "conversion" of 128 kbps aac or opus into "320 kbps" mp3s (or whatever random bitrate). The least one could do is just listen to the aac/m4a or opus files without converting them yet another time.

    Losssy-to-lossy is a bad idea. Getting mp3 off YouTube means very crappy experience, even if it is somewhat popular

    Software that my parents or yours can use is definitely a good thing. Not everyone needs to chase the cutting edge.

      That was my point but I feel like everyone that replied to me thought I was making the opposite. I think your submission is awesome :)

  > I see no reason to encode stuff into .mp3 for me it comes down to: 1/ everything can play mp3s 2/ audio quality at 320kbps is good enough for me 3/ disk space is just not an issue anymore so I don't need more efficient codecs

  Most people know what an "mp3" is. Not many people know what an "aac" or "opus" is. Mp3 just works practically everywhere, but aac and opus - not so much.

I like simple tools like this. I hope version 2.0 will have support for arbitrary formats since phones record audio in anything but mp3.

It appears you're including libmp3lame, and linking against it, but I don't see any copy of their LGPL license included (and it's not output in 'strings', so it seems like there's probably not a menu item. I don't run windows, so I can't really check that part). To avoid violating libmp3lame's copyright, you need to include their notice somewhere in your application.

  Thanks for pointing it out. I've updated the license file accordingly.

I've used https://www.mp3tag.de/en/ https://www.mp3tag.de/en/ for this since, apparently (per my emails for donating to the project), 2008.

Cool. I would certainly use this on windows if I ever need to wrangle mp3s. On linux, puddletag provides a decent GUI for modifying audio file metadata. For bulk editing / transcoding, parallel with ffmpeg and (fd)find works very well.

Mp3tag is a really good program for this task, how does this one compare? I once used MP3Tag to fix some MP3s where the artist got screwed up because the track name contained a slash, and these files had already been put into separate directories by artist. Since you could match album even recursively in directories, it was easy enough to move all the files back to their proper place.

Thanks for all the comments. This is a tool for editing MP3 files at the frame level. It’s similar to mp3DirectCut and mp3splt in some ways, but today’s hardware enables more advanced editing of lossy audio. Any feedback is appreciated.

  In a change log simply stating "bug fixes" is not enough, because as a user, it's not clear whether or not any of those bugs that you have fixed has affected me. This might be my personal opinion though, I'm not sure, but when some software releases an update that says "fixed the issue where X goes wrong because of Y" and that specific thing has been annoying me for a few months, it kinda makes me happy in that moment, because I know I can expect the next update to suck a little less. Might be something to consider, but at least writing down the scope of the bug would be already better.

Cool project ! One nice feature I can request is the ability to set the same volume level across all the audio files.
