Figure 26. Structure of the Digital Effects Processing for Independent Channel Processing
The coefficients for this filter implement a variety of sound effects, with bass-boost or treble boost being the most
commonly used in portable audio applications. The default N and D coefficients in the part are given in Table 2
and implement a shelving filter with 0-dB gain from DC to approximately 150 Hz, at which point it rolls off to a
3-dB attenuation for higher frequency signals, thus giving a 3-dB boost to signals below 150 Hz. The N and D
coefficients are represented by 16-bit two’s complement numbers with values ranging from –32768 to 32767.

The digital processing also includes capability to implement 3-D processing algorithms by providing means to
process the mono mix of the stereo input, and then combine this with the individual channel signals for stereo
output playback. The architecture of this processing mode, and the programmable filters available for use in the
system, is shown in Figure 27. Note that the programmable attenuation block provides a method of adjusting the
level of 3-D effect introduced into the final stereo output. This combined with the fully programmable biquad filters
in the system enables the user to fully optimize the audio effects for a particular system and provide extensive
differentiation from other systems using the same device.
