Elliptic BLEP - High-Quality Zero-Latency Anti-Aliasing

Explore a conference talk from the Audio Developer Conference 2024 where Geraint Luff presents "Elliptic BLEP," a high-quality zero-latency anti-aliasing technique. Learn about the origins of aliasing in basic waveforms, nonlinearities, and hard-sync synthesis, and understand how BLEP (Band-Limited Step) techniques can reduce these artifacts. The presentation introduces a novel IIR-based approach using Holters-Parker resampling that offers zero-latency implementation with superior aliasing reduction based on elliptic filters. Discover the practical applications of this technique, which has been released as an open-source C++ library that can also function as an arbitrary-rate resampler for modulated delay lines and sample playback. Perfect for audio developers, DSP engineers, and anyone interested in advanced audio processing techniques.
