The Loudspeaker Phase Arbitrator is a real-time Digital Signal Processing program that runs on MS Windows XP. It is VST compliant, which means that it can be used as a processing plug-in in a variety of digital audio applications. To make it more appealing to audiophiles it comes with a shell program that allows the user to take advantage of an ASIO compatible sound card without the need for purchasing and learning additional software.
The Loudspeaker Phase Arbitrator takes the well known DSP concept of forward-reverse processing that results in linear phase processing and spans it across two domains- digital and analog. The reverse part takes place in the digital domain through the Arbitrator; the forward part is performed by loudspeaker's crossovers. The Arbitrator doesn't change the frequency content of the material it processes- only the phase. When properly dialed in, the phase shift introduced by the Arbitrator is very close to mirror image of the phase shift introduced by the loudspeaker's crossover. The Arbitrator also compensates for the phase shift caused by the low frequency roll off of the box/woofer combo.
The combination results in near zero phase shift, or transient-perfect reproduction while preserving the loudspeaker's own frequency response.
The Arbitrator is a perfect tool for people who own passive loudspeakers and enjoy their performance in the frequency domain. The Arbitrator can add another dimension to the reproduction by dramatically improving the system's impulse response.
The Phase Arbitrator is designed to process audio in the most transparent way. It uses 64 bit math at sampling frequencies up to 192kHz (hardware dependent). It outputs 24bit audio.
