8 Channel Surround Panner
Posted: 11 Dec 2013 21:43
I thought this was possible in Lemur but now I'm not so sure...
The situation: doctoral dissertation using 8 independent mono channels of audio. The audio is NOT 5.1 or 7.1 since those are forward-biased formats with more speakers towards the front of the listening area because these formats were designed for film. My project considers all directions equally so the speakers are spaced equally around a ring - one speaker every 45 degrees.
The Need: to be able to adjust the volume (panning) of all 8 channels simultaneously using a joystick type of interface for a test subject. This means that one "ball" (in Lemur parlance) sends appropriate continuous controller variables for 8 simultaneous different continuous controllers (which eventually control the volume coming from each of the 8 speakers) so that the sound can be moved around the circular playing field and left at a certain point determined by the user. Basically, the close the ball is to an onscreen virtual speaker, the louder the sound should be from that real speaker.
Since the speakers are in a ring, the onscreen interface must look like circle which takes out the Multiball tool. RingArea starts with the circular interface but appears that the attraction function can not be turned off adequately. For both of these there is the added issue that I am not looking for an "X-Y" controller because that is only 2 dimensions. I would like to control 8 dimensions with one ball.
I looked around the User Library and also did several searches for surround panners but not much luck. Can this even be done in Lemur with some fancy under-the-hood programming?
