The Phase Arbitrator is
a digital signal processor that alters the phase relations
of the material it processes without affecting its frequency
content. If dialed in correctly the phase response of the
Phase Arbitrator is a mirror image of the phase response introduced
by the playback loudspeaker's crossovers. This results in
proper alignment of frequencies in the time domain, or Transient
Perfectness. Read more about it here.
The Frequency Allocator
is a 2 in- 8 out DSP crossover laid out as a series of individual
IIR biquad LP and HP filters with parametric EQ section, delay,
polarity and output gain per leg. It lets the user dial in
highly customized crossover curves up to 42dB/oct and beyond.
It is preceded by a full Phase Arbitrator section, so that
any active loudspeaker using the Frequency Allocator as a
crossover can be made transient perfect as well. Read more
about it here.
The Frequency Allocator Light
is a simplified version of the Allocator. It lacks the Phase
Arbitrator section, but it still allows for dialing in of
highly customized crossovers. It exhibits very low latency
and low CPU loads that make it ideal for use with loudspeakers
in a Home Theater setup. Multiple instances can be run simultaniously
for a very advanced surround sound system. Read more

All of these processors are VST compatible (Steinberg's Virtual
Studio Technology) for use in ever expanding array of professional
sound editing programs, but come with their own VST host-
called VSTShell. VSTShell relies on ASIO compatible hardware
for inputs and outputs. Users with no ASIO compatible cards
can use third party VST hosts that are capable of utilizing
generic Windows sound cards. A recommended solution is the
Winamp Allocator Output is a free plugin that allows use of Frequency Allocator from within Winamp Media Player. It's an elegant solution for owners of ASIO sound cards that can't route audio internally. More about it here.
