I accidentally saved a file of low freq sine waves (chromatic octave
starting 55Hz down to 27Hz -6 dB fs) in .WMA format using Adobe
Audition 1.5. Recalling the WMA file into Audition shows what looks to
be 'noise' as in +/- 2 dB amplitude variations. The noise does not seem
to be harmonically related to the test frequencies and is barely
audible but it looks aweful on the waveform display.
I assume the WMA encoding in Audition is good as the rest of their
processing sounds to be first rate. I see nothing at all like this with
MP3 files. Any insights?
