fast panning issue

[markuse]

Hi!

Has anybody ever noticed an unconstant volume level when doing fast pannings on a mono track, that's routed to a LCR output? I'm talking about pannings shorter than approximately 12 frames. It sounds pretty much like there would be a gap in the signal. I've bounced the LCR output as mono summed , to see what's going on and make sure it's not a speaker problem.

check out the following screenshot:

The screenshot correlates pretty much to what I hear.
I've checked this with a 1kHz test tone and pink noise as well as with cars passing by.

best,

Fast panning = fast volume changes. Fast volume changes = amplitude modulation. That's what's happening here.

thanks,

that sounds logical. I checked out spreading the test tone on 3 tracks that were "fix panned" to L, C and R. Same result, if you translate the panning automation to the volume automation. It does work however, if you manipulate the lenght of the fades a little bit. So that means no fast pass bys possible, using on track.
