It's not a known issue, and digital recording is, in general, quite
incapable of inadvertently lowering pitch. It's possible that the problem
is in the original analog playback, although you seem quite certain that is
not the case.
The only thing I can think of is a situation where the sampling frequency of
the Audacity project differs from that of a given track. However, to
achieve only a 1/2 step reduction, the difference in sampling frequencies
would have to be small. Could the difference between 44.1KHz and 48KHz
induce only a 1/2 step frequency reduction?
When you detect a lowering of the pitch, do you also detect a slowing of the
tempo?

Subject: [Audacity-users] mp3 exports are sometimes a little lower in
pitchthan tape cassettes
| Hello,
|
| Sometimes when I record a tape cassette into audacity, when I export it
| as mp3 the mp3 sounds about 1/2 step lower in pitch than the original
| tape...but this does not always happen...even though my settings remain
| the same throughout tests.
|
| I use export multiple for all my exports.
|
| Is this a known issue? Does anybody know what might be causing this?
|
| I'm using Audacity 1.3.2 beta on Win98SE. Low CPU machine should not be
| the problem should it? Because it works fine most of the time. Old
| 300mhz processor as dedicated machine to record tapes into it.
|
| Thank you very much for any ideas about this.
