Heh, well you mean upload the actual music files? Well.. i mean, it's just basically any vbr mp3 you would have laying around. If you have a CBR mp3 and VBR mp3, you can easily see what happens. The CBR will cut perfectly where you end it. But the VBRs leave about 4-5 seconds over the spot you end the split. I used a 192kbit CBR mp3 and it split perfectly where i cut it. But when i used a V0 VBR mp3, well the point where i ended the cut, i get about 4 seconds more.
Also, the seeking is kind of a hassle too, but nothing too major. I always have to pause the mp3, in order to seek/search. If i use the slider while its playing, it skips and locks up for a few secs and repeats random pieces and takes about 6-8seconds to recover. So i always have to pause, mark it, search, play, pause, mark, etc, rather than just have it playing as i skip around with the slider.
My only main complaint is just the extra 4-5 seconds or so that gets added on to the end of a split when working with VBR mp3s. Now i could convert them to a CBR bitrate myself, but thats an extra step people will not want to deal with. Just so you know too, this only happens with MUSIC files. When i split xvids/wmvs that use VBR audio, it always cuts them perfectly where i split.
Btw, the joiner problem i mentioned can now be disregarded. Its normal for some info in the tags to get out of sync when joining 2 files, since you cant obviously have the same exact title name and bitrate info listed twice lol. Two VBR files when joined, always shows the first track's time. With two CBR mp3s, well the time is shown as the sum of both, but...thats really not a big issue and probably not possible to fix anyways, as thats probably how the mp3 codec works in that case.
Oh i forgot something else too. Just now i cut an Xvid that uses LAME codec as the audio. The piece i cut still shows LAME. However, when cutting a single MP3 that uses LAME, the cut piece shows as FHG. Most people will prefer the cut MP3 to be exactly the same as the original, with the tags and all info carried over. Im not sure if its re-encoding it, as the bitrate is still the same, but something in the program is using FHG when it splits mp3s.
