Variable Bit Rate Audio

Hi there,

I wonder, has anyone noticed this issue?

I use the paid for version of MusicMatch to manage/record etc all of my
audio, and I have the record option set to 100% VBR and MP3.

I just recorded Magical Mystery Tour from a CD so that I can use some of
the tracks in a video....the video at the moment is 19:52 or so minutes
long and in the time line I could see all of it. So you can imagine the
initial surprise when I dragged the "Magical Mystery Tour" to the audio
track on the timeline and found that it was longer than the video itself!!!
This particular track claims to be almost 20minutes long when in fact it is
just 2:51 ...very odd

But it gets worse...If you play the audio track from the very beginning it
plays properly and at 2:51 it fades correctly to silence but the timeline
indicates that the file continues up to 19:52 and if you leave it all you
get is silence....but if you click anywhere on the timeline the music
starts again from what seems to be a random position in the music, and if
you click the timeline just before the 19:52 position you get the end of
the track as if it was just before the real 2:51 position.

If you select one of these audio tracks within Windows Explorer and look at
its properties you find that each of them is reported to have a different
bit rate, and that is of course correct. Some of the tracks have a bit rate
as high as 570Kb/s

It makes using MP3's recorded in this manner very hard to use.

Hi again,

I should have also said...when I add normal fixed rate audio to my
timeline, I do not get this issue.
