Spatialization review, transfer functions, compression

a) important factors for effective spatialization
   - delay for purposes of ITD vs. delay for purposes of distance simulation for Doppler effect
   - intensity for IID purposes vs. intensity for azimuth angle stereo panning
   - azimuth angle for constant-power panning
   - amplitude changing inversely with distance (or more steeply)
   - distance-based delay for Doppler effect
   - mix of direct sound to reverbed sound changing with distance in a closed space
   - lowpass filtering due to air absorption at large distances
b) definitions of frequency, pitch, harmonics, partials, overtones, equal-tempered tuning
c) transfer functions for distortion and synthesis
   - chebyshev polynomials for careful harmonic emphasis
   - more complex transfer functions for synthesis and extreme distortion
   - implementing both in MSP
d) definition of decibel, and the reasons for its use
e) dynamic compression without transfer function
   - low frequency amplitude monitoring (with average~, avg~, or peakamp~)
   - describing amplitude as average, RMS, or peak value (advantages of each)
   - definitions of compression, expansion, threshold, compression ratio, latency, lookahead delay, attack, release, makeup gain, pumping, and multi-band compression
   - examples of uses of compression
   - pseudo-code implementation of a compressor
   - example of a multi-band software compressor in Digital Performer
   - implementation in MSP
