LIEVANO-TORRES, Pedro P; ESPINOSA-DURAN, John M  e  VELAZCO-MEDINA, Jaime. Algorithm Implementation in High-Fidelity Digital Audio Effects Using Programmable Hardware. Ing. Univ. [online]. 2013, vol.17, n.1, pp.93-108. ISSN 0123-2126.

Digital audio effects are generally implemented in software using DSP or PC; nevertheless, some implement ations us ing dedicated hardware are currently being considered. This paper presents the implementation in hardware of fifteen algorithms for the real-time processing of digital audio effects with sampling rates up to 100.88 MSPS and high-fidelity. Designs were simulated using DSP-Builder and were synthesized in the FPGA EP2C70F896C6. The hardware verification tests of the implemented effects show that the designed blocks can be used as IP cores for the design of a multi effects processor embedded in a SoC.
