A new method is presented in this paper for using general purpose programming tools of graphics processing units. It aims to calculate the modified discrete cosine transform in audio coding and compression algorithms for popular audio formats such as MP3, AAC/AC-3, and WMA. The proposed algorithm consists of matrix multiplications that are performed by the graphics processing unit. The experiments show that the proposed implementation is considerably faster than usual implementations based on early algorithms for standard hardware, so that the proposed approach can be considered for critical applications in real-time multimedia signal processing.

Abstract
A new method is presented in this paper for using general purpose programming tools of graphics processing units. It aims to calculate the modified discrete cosine transform in audio coding and compression algorithms for popular audio formats such as MP3, AAC/AC-3, and WMA. The proposed algorithm consists of matrix multiplications that are performed by the graphics processing unit. The experiments show that the proposed implementation is considerably faster than usual implementations based on early algorithms for standard hardware, so that the proposed approach can be considered for critical applications in real-time multimedia signal processing.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
