Wavetable frame size

Wavetable frame size is the number of samples in each single-cycle frame, held constant across the whole table.

Sizes are almost always powers of two (256, 512, 1024, 2048) because table-lookup oscillators and FFT-based tools index efficiently at those lengths. The choice trades spectral resolution — how many partials a frame can hold, and how cleanly low notes can stay bright — against memory and editing detail. Since importers slice packed WAVs by this length, it has to match the target instrument's expectation.
