minBLEP
minBLEP, short for minimum-phase band-limited step, is a technique used in digital audio synthesis to reduce aliasing caused by discontinuities in waveforms. It is a variant of the band-limited step (BLEP) method and is designed to produce cleaner transitions in digitally generated signals.
The core idea is to replace a sharp waveform edge with a short, precomputed segment whose spectrum
In practice, a set of minBLEP waveforms of different lengths is precomputed and stored in a table.
Advantages of minBLEP include effective alias suppression with compact transition windows and better temporal localization, making
