delay-reverb

What problem does it solve?

Delay lines and reverb are essential for shaping room acoustics in digital audio. This skill provides a compact design that uses circular buffers, fractional delay, and various filter topologies to realize reverb effects.

Core Features & Use Cases

• Efficient delay buffer: power-of-2 sized buffers with bitmask wrapping for speed.
• Fractional delay interpolation: linear, cubic, allpass, and sinc options for sub-sample accuracy.
• Reverb topologies: comb filters with damping, Schroeder allpass, and Freeverb-inspired networks; FDN concept for dense tails.
• Use Case: Build a small room reverb for a synth or a longer ambient tail for a mix.

Quick Start

Instantiate a DelayLine with a maximum delay, configure a damping parameter, and connect a feedback path through a comb/FDN structure to produce a reverb tail.
