Signal Wizard 2.5 is a unique, integrated system for designing, downloading and running very high performance filters and other algorithms in real-time. It includes an intuitive software system and a hardware module based on an advanced digital signal processor  that implements the desired operations. Once specified, the software downloads the configuration to the hardware module via a serial link where it is executed in real time.

The system requires no knowledge of digital signal processing (DSP) theory on the part of the user, mathematics or programming. Due to its flexibility, it is particularly well suited to the real-time processing of audio signals. High quality analogue signal conditioning and a stereo 24-bit resolution codec provide extremely high resolution. Applications include audio signal processing, inverse filtering, noise cancellation, sensor signal conditioning, spectrum analysis, sine and arbitrary function generation.
