  1. Many thanks. Click for files wrt vbr mp3s: as I say, foobar2000 (android app and pc) has no issues with any length + cuesheet I've ever tried - I have some 4hr+ files. EDIT: meant to say that I think the transition from (cue sheet) track 5 to 6 is likely the best one to focus on when testing as it's the most obvious track change.
  2. I've been using Poweramp for many years now (it's a great player and love it, so many thanks) and it *seems* that the issue with inaccurate seeking/playback for vbr mp3s has become more prevalent. I cannot be sure on this, but I hadn't noticed the issue until very recently (using build-941-944). I have 1000s of audio files that are DJ mixes (often 1-2hrs long) and many have cue sheets. Most of them are in the mp3 format. So far, all the cbr ones play fine with a cue sheet, but the vbr ones are often considerably out of time. One file (57 mins long with 9 tracks in the cue sheet) I've just tested was almost exactly 60 seconds late! Using that one as an example, it's a LAME 3.100 -V0 encoded mp3. So, a new mp3 encode with full seek tables (vbr header info etc) and fully compliant. I used a tool called MP3Packer (actually used the frontend called WinMP3Packer) to "losslessly" (no re-encoding) change the vbr mp3 to a cbr mp3. When tested with the cue sheet it works fine. I did this to prove that the file isn't the issue, but it being a vbr and how Poweramp handles it with the cue sheet is. So, I'm wondering has something changed in Poweramp? If not, then could this be looked at please? Maybe looking into the mp3 decoder. I don't have any issues accurately playing vbr mp3s with cue sheets in the Android foobar2000 app nor the foobar2000 Windows program (my main media player on my computer) with these files, just to give some comparison. - I understand that the way to eliminate this issue for the user is to use cbr mp3s or a format like aac when using cue sheets. The latter (and other formats) is fine when those are the native formats (or if there's a lossless version that can be transcoded to cbr mp3 or aac etc), but as I mentioned at the start, 1000s of these long (DJ mix) mp3s have been acquired over 20+ years of internet usage and that's the only format I have. Plus, I wasn't expecting a modern player such as Poweramp to have issues with vbr mp3 playback with cue sheets. I know in the early to mid 2000s many mp3s were created without seek tables, which caused playback issues, but lame resolved that and decoders were improved to handle it. I'm happy to provide the mp3 (vbr & cbr) files with cue sheet for someone to look at / test.
