Hi,
I'm new to Core Audio (and audio programming in general) but I'd like to implement my own ambisonic panner. It seems like I should be able to do this using a Matrix Mixer, so I started looking at its properties. Could someone explain what each of these are?
kMatrixMixerParam_PreAveragePower = 1000
|
kMatrixMixerParam_PrePeakHoldLevel = 2000
|
kMatrixMixerParam_PostAveragePower = 3000
|
kMatrixMixerParam_PostPeakHoldLevel = 4000
|
kMatrixMixerParam_PreAveragePowerLinear = 5000
|
kMatrixMixerParam_PrePeakHoldLevelLinear = 6000
|
kMatrixMixerParam_PostAveragePowerLinear = 7000
|
kMatrixMixerParam_PostPeakHoldLevelLinear = 8000
|
I'm aware that 3DMixer supports 1st order ambisonics, but I'd like to use a higher order approximation. The other issue is that 3DMixer won't support decoding to some arbitrary speaker array; In my case 11 speakers arranged in a circle around the listener.
Thanks!
Andrew.
