Creating a Convolution Reverberation Effect from Impulse Responses in Physical Spaces

Abstract

This paper gives detail to the implementation of convolution of an input signal with an impulse response recorded in a physical space in both the time and frequency domain in order to model a reverberation effect. The Impulse Responses used in this project were recorded in physical spaces using sinusoidal sweeps and recorded into one channel. The Input Signals used were recorded using various instruments into one channel. This paper describes the differences between time domain convolution and FFT convolution with a focus on the uses of FFT convolution in reverberation effects.
