Abstract 3 This paper explains the convolution reverb, a method that enables users to add realistic sounding reverberation to audio material that was recorded in neutral sounding rooms. In particular, the possibility of computing the effect on the GPU using OpenCL is discussed, to make use of the high concurrency of the problem. This paper aims at the development of a VST plugin that utilizes the GPU accelerated convolution algorithm, so that it can be used for audio software solutions.
