Overview

Introduction

This is a reverb implementation based on Freeverb, a public domain reverb written by Jezar at Dreampoint in 2000.

The library is written in C and is distributed as a single header file. It should compile on pretty much any platform with a C89 compiler as long as floats are available. If you find a platform on which it does not work, please let me know.

IMPORTANT: The reverb currently only works with 1 or 2 channels, at sample rates of 22050 HZ and above. These restrictions may be lifted in a future version.

Features

verblib has the following notable features:

  • Easy to integrate (the library is stored in a single file).
  • Parameters such as room size, damping and stereo width.
  • Portable ANSI C89 code with no external dependencies.
  • No licensing restrictions (public domain or MIT licensed with no attribution requirements).
