Multiple Read/Write Pointers

Misc. Refinements:

• Using multiple read pointers, multiple moving listeners are simulated
• Each read-pointer signal can be filtered to simulate propagation losses and radiation characteristics of the source in the direction of the listener
• Read-pointers can move independently to simulate the different Doppler shifts associated with different listener motions and relative source directions.
• Using multiple write pointers, multiple moving sources are simulated
• Watch out for aliasing due to upward Doppler shift
