Application of graphics processing units in audio signal processing

Intensive development of graphics processing units in recent years has led to their use in variety of applications, including the processing of audio signals. This paper presents the viability of those processors and their programming model in dealing with two audio effects - audio amplifier and digital equalizer. The parallel application is implemented as a plug-in for Audacity using CUFFT library for the fast Fourier transform. Evaluation of parallel implementation has shown a significant speedup compared to its sequential counterpart.
