Algorithm design in matlab with eye on efficient implementation in dsp.
There was little point in wasting my time by learning asm for the dsp, 
when VLSI Solution already had a bunch of people who were experts at 
writing optimized code for it. Matlab also allowed a higher level view of 
the algorithms without implementation details getting in the way.

% Replace with 2^x table lookup
decay = decay_base * 2^-(octave * decay_scale);

is a lot easier to understand than some 10-20 lines of fixed point C code.
