Efficient Specialized Methods

We have already mentioned inverse-FFT synthesis as a means of greatly decreasing the cost of additive synthesis relative to a full-blown bank of sinusoidal oscillators. In this section, we summarize a number of more specialized methods which reduce computational cost of additive synthesis, and which are widely used.
