So my mp3 file is actually about 50 seconds long (it stops playing after this time - there's no dead air at the end). When I play it in Windows media player or import it into PowerPoint, it shows it as being over 3 minutes long. I'm having this problem with a few files.
Would this be a sampling rate issue, or is there some wierd Audition quirk I'm not familiar with? Why does the detected length show up as not matching the actual length?
So I found that opening them with Audacity (a free audio editing program) and resaving fixes the issue. I'm still not sure why it won't work using Audition, though. Any thoughts?
