The Bidat algorithm analyzes the digital audio samples for relative accelerations and then chooses the type of filter most appropriate for that segment of data. This intelligent process results in a frequency response which is flat to 20KHz for CD playback. More important, it produces a uniquely pure impulse response without Gibb’s ringing. For example, a square wave will have clean rectangular transitions and no ringing.
The Museatex Bidat can claim transient response demonstrably MORE faithful to the recorded signal than the best analog playback systems for vinyl LP’s and open-reel tapes. The undistorted transient response of the Bidat means the algorithm contributes no coloration of its own to the processed audio. This performance eliminates the “digital washout” of sonic subtleties and the harshness heard in listening to a conventional interpolating algorithm. For the first time in audio engineering, the full advantage of Digital Signal Processing has been used in the service of signal fidelity by the implementation of a smart filter which could never have been built with analog circuits.
