This paper describes a new design method of dynamic range controllers, such as compressor, limiter, expander and noise gate, on a DSP for digital audio systems. ...
The digital signal processing on DSP is about 130 steps for the compressor, and 120 steps for the expander with a given expansion ratio equal to or smaller than 15. ...
If such analog dynamic range controllers were used in a digital audio system , the digital-to-analog and analog-to-digital converters have to be used, which must increase the cost and complexity of the ...

I also argue that it does not suffice to replace Chalmers' favorite model with a better abstract model of computation; it is necessary to acknowledge the causal structure of physical computers that is ...
For this reason, a philosophical account of implementation should remain neutral in the discussion over modeling computational systems on the level of behavioral equivalence. ...
