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
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.
