What is the difference between the interpolation algorithms?
Interpolation is required when a sample is played at a different speed. It tries to guess the values between two sample points in order to give a better curve in between these points. • None: Nothing is done to improve the quality of the sample. It will just take the nearest value. Aliasing occurs. • Linear: A line is drawn between sample points. This is a basic approximation and recommended for playback use. • Cubic: A curve is drawn between sample points (four points are used). This is a better approximation and is more than decent for playback use. • Sinc: An almost perfect curve is drawn between samples points (fifteen points are used). This is the recommended quality for the final exporting to wave. Use for playback only on high-end computers. Only registered users can use this option.
