That's thus far always resulted in a compliant MP3. When I get mp3s that aren't produced by me, I always run through foobar2000: Rebuild MP3 Stream | Optimize file layout + minimize size | Fix VBR MP3 header A bundle with the WinMP3Packer frontend is here: For what it is worth, it works best on valid files.īut MP3packer is fun. Also, gapless info could go out of the window, if you want to keep that. it can so happen that mp3packer will ditch broken frames and that could actually sound worse. Quote from: Porcus on 16:24:05 I don't know what options will be applied upon drag+drop at exe. ![]() This process is lossless, but that is much work, and takes time. To avoid this, you need to use MP3packer before processing to increase the bitrate to the maximum, and then compress the file down again. If you place the cut in a quiet section, there won't be any glitch. Some frames at the start are always incomplete after cutting because of the bit reservoir. No need to recompress the entire stream.ĭon't worry about gapless data in this case because you have intentionally cut a fragment, so the original values are no longer meaningful. You can use a hex editor to rename this field or an old version of Foobar2000 to remove this data from the Comment, or any other program that allows to do that, for example, Mp3Tag. Technical info has no bussiness being in the tags. Mp3DirectCut just passes this tag field through like others. ![]() Most other software record the duration of VBR files in a different data structure called a Xing header. The wrong length is saved in the tag field "iTunSMPB". Thanks, any further pointers are very welcome Originally (15 years ago) I had some mp3 players that struggled with vbr, so I have an irrational aversion to it!įoobar's 'Fix VBR Header' utility fixes the metadata fine and reports the durations as they should be. I think I'd rather stick with CBRs, though. I haven't noticed any degradation in quality (but they are 1.5 hours long and it will take a while to listen all the way through). Mp3packer64.exe doesn't change the reported length of the file (as-per the OP) for me - those 3 minute samples I attached still report as 1 hour 57min in Foobar after mp3packering them. It is the same if I try it on a brand new mp3 file I just made on Audacity which is 100% definately CBR to start with. It does seem to be a VBR file (the bitrate on the Foobar2000 status bar jumps up and down by +/- 2 kbps as you play it). My experience trying these on the full (1 hour 40 min) files is that mp3packer64.exe creates a new file with the old filename suffixed with "-vbr". ![]() I have also experimented with doing each type of those edits individually, but same result. (some earlier edits were done (WAV) in Cool Edit Pro or Audacity)įiles are CBR mp3, mostly 128kb/s stereo.Ĥ) I'm not pro or a programmer, so would prefer an easy/baby-language fix using freeware software, if possible.ĥ) I would prefer a solution that doesn't lose audio quality through re-encoding.Ħ) The edits are: topping and tailing the lead-in/out, plus in the middle of the show, 'fade-out/chop/fade-back-in' a few times. ![]() manually changing/correcting the length metadata in the final files after the eventģ) I believe that the history/ lineage of the files is. using some other settings in mp3DirectCut or I don't necessarily need to fix the few that I have already done, (although that would also be nice), I mainly want an effective method of making edited mp3s that show the right length, going forward. How, can I get around this please? I want a method that gives output files with the correct metadata. Other players (vlc, MS Groove) and MSExplorer report the correct (edited) length. I'm editing-out the news-and-travel from some mp3 radio shows, using mp3DirectCut (v2.34) (so I don't have to re-encode the mp3s and lose quality).Īll is fine & dandy except that in the finished article, foobar2000 (v1.4.6) sees the length/duration as the original (unedited) length.
