L PASS FILTER The all pass filter has a flat frequency response from 0 Hz to the Nyquist frequency however the phase response delays different frequencies by different amounts This provides a very distinct sound approaching a phasing effect Moorer defines the most natural sounding unit reverberator to contain a number of comb filters and a single all pass filter He also states that the use of more than six parallel comb filters and one all pass filter does not significantly enhance reverberant qualities Therefore only a single all pass filter is implemented here The delay must be set to six milliseconds or less as longer delays produce what Moorer describes as an audible repetition The gain constant g of the all pass filter is 0 7 The block diagram for the all pass filter is shown in Figure B 4 Figure B 4 All pass Filter B 8 DSP56009EVMUM MOTOROLA Sound Field Processing Example De Correlation Routine The value z n which is the value of the upper gain stage is computed first the delay z is accessed from the EDRO EMI Data Read register and v n is computed The parallel move feature of Motorola s DSP56K architecture allows this arithmetic to be achieved in only four instructions as shown in Figure B 5 T move b y0 1 transfer x n to yO for 2 multiplication get 1 2 at 1 3 mpy yO yl a x r0 x0 z n k x n 4 get y n T from EDRO to x0 5 macr 0 1 5 r4 compu

Y FOR SOUND FIELD PROCESSOR B 15 REVERB TIME 15 B 17 DSP56009EVMUM MOTOROLA Sound Field Processing Example Introduction B 1 INTRODUCTION The phrase sound field processing seems to embody a sense of extra space added to an original sound With the advent of practical multichannel sound processing certain sound fields artificially became attainable and edifies the listening environment when certain theaters or other settings are replicated in software In order to create the delay and reverberation elements that typify certain acoustical spaces filtering and delay components must be instituted Therefore DSPs ideally might handle even the toughest simulation The soundfield processing example offered here is a design based around studies performed independently by Manfred Schroeder and James Each provide important insight into effective algorithms that create artificial reverberation This appendix will explain specifically the reverberation blocks inherent in one particular example however this example provides only one of many as defined by Schroeder and Moorer This implementation uses filter coefficients collected by Schroeder that imitate the Boston Concert Hall A four channel output is generated left front right front left rear and right rear with a summed output feeding the center channel which may also be lowpass filtered to be used for a subwoofer channel T
