nDSP: A platform for audiophile software audio processing

This paper proposes a platform referred to as nDSP to interconnect different software audio signal processing effects which are modularized. The new platform is focused on having all processing done by the system CPU at higher quality than that achieved using hardware DSPs. The software representation of the module inside the platform is defined such that its state can be externally controlled, therefore the design of self-tuning filters is allowed. The design aims the further use of software audio signal processing in low-cost audiophile loudspeaker systems taking full advantage of the new personal computer hardware products.
