Real-Time Convolver™ Software

(This software is no longer support)

The Real-Time Convolver is a hardware / software add-on to the Hypersignal®-Acoustic software package which implements very long FIR filters (VLFFs) in real-time. VLFFs can be created by Hypersignal-Acoustic software using equalization functions, FIR/IIR digital filter design, difference equations waveform editing, or imported from external waveform files. VLFFs can then be downloaded to supported hardware in ASCII or binary form using Hypersignal-Acoustic software or DirectDSP software.

Real-Time Convolver Feature Summary

• Using Sig32C-4 or National Instruments AT-DSP2200 board (see below), up to 10,000 pt. impulse response can be applied in real-time at 44.1 kHz stereo (one filter applied to both channels)

• Binaural filtering or mono operation

• 11.025, 16, 22.05, 32, 44.1, 48, 51.2 kHz rates supported

• Waveform file mode included, for accelerated file-based processing

• Software consists of Hypersignal-Acoustic, plus Real-Time Convolver™
