    Abstract

    In recent years, the DSP group at the University of Manchester has developed a range of DSP platforms for real-time filtering and processing of acoustic signals. A next generation system has now been designed, which incorporates a processor operating at 0.55 Giga MMACS, six input and eight output analogue channels, digital input/output in the form of S/PDIF and a USB interface. The software allows the user, with no knowledge of filter theory or programming, to design and run standard or completely arbitrary FIR, IIR and adaptive filters. Processing tasks may be described and linked using the graphical icon based interface. In addition, the system has the capability to emulate in real-time linear system behaviour such as sensors, instrument bodies, string vibrations, resonant spaces and electrical networks. Tests have confirmed a high degree of fidelity between the behaviour of the physical system and its digitally emulated counterpart. In addition to the supplied software, the user may also program the system using a variety of commercial packages via the JTAG interface.
