Inaccuracies with MP3 properties

[richmcc]

I have a series of voice only MP3 files that were resampled from 44100 to 22050 with a Bitrate 48khz. When I get the Track Length property it is somewhere around half of the actual length e.g GetProperty reports it as 2:55 when it is actually 6:23. Also the Bitrate reports different numbers for different files.

When I examine the files in Music Match the information is correct.

Any ideas what is going on here and how I can get/calculate the correct Track Length from within the program?

Try encoding your MP3s with a different tool? Not sure but that might help. I use Sound Forge and AMS seems to pick up the info OK...

Thanks for the quick reply, I may try that.

I was wondering if AMS assumes a 44100 sample rate and uses that to get the Track Length?

That would explain the it showing MP3s sampled at 22050 at about half the actual length.

One would assume then that it would have been exactly half and not approximately but I'm not sure...
