Considerations for Wavetable Lookup

Indeces to $x(n)$ are constrained to be integers between 0 and $N-1$.

If signal $y(n)$ is used to index wavetable $x(n)$, its values must be

• between 0 and $N-1$,
• integers.

Audio signals in Pd aren't integers and don't usually (shouldn't) exceed an amplitude of 1.

Additional processing must be done to signal $y(n)$ to make it usable for wavetable lookup.
