Wavetable Interpolation
A precise tool.
What is the Wavetable Interpolation & How does it work?
Wavetable interpolation is a technique used in electronic music synthesis to smoothly transition between different waveforms stored in a wavetable. This method enhances the timbre and expressiveness of synthesizers by allowing for more nuanced sound design.
The process involves interpolating between adjacent samples in the wavetable based on the current position of the oscillator. This interpolation can be linear, which is computationally efficient but may introduce aliasing artifacts, or higher-order methods like cubic spline interpolation, which provide smoother transitions at the expense of increased computational complexity.
y(t) = sum_{i=0}^{N-1} w_i cdot f_i(t)
y(t) = interpolated sample at time t, w_i = weight of the i-th waveform, f_i(t) = i-th waveform function
