Have tried it, on and off....
I've tried Audacity on and off over the years, but have always found it a bit more fiddly and less intuitive that the "rival" Goldwave. Yes, I accept that Audacity is open source, cross platform and free, whereas Goldwave is not. But you can get the fully functional trial/demo version for free, and the lifetime purchase fee is minimal for what it does. I've edited 1000's of hours of audio with it over the years. Just the X/Y and visual spectrum displays are worth it on their own.
It is quite easy to set a heterodyne filter for those "208" recordings - just introduce a sharp notch at 9khz, or a roll off over 8khz - extremely easy to see on the spectrum graphic. I assume Audacity can do the same. Also useful for correcting those old tape/cassette recordings where the tape deck never ran at the exact speed.....
Biting the hand that feeds IT
