PHA-979 is a PC VST plug-in which allows you to apply an
arbitrary phase shift to the program material. What is meant by
the phase shift here is a simultaneous shifting of all
frequencies across the active frequency range of the signal by
the given phase shift value. This process does not harm the
phase relations within the signal being processed. For example,
you can shift the phase of the signal by 90 degrees and then
shift its phase by 180+90 degrees to get the original signal as
a result. In PHA-979, this is achieved by using a linear-phase
design.

PHA-979 can be very useful during mixing sessions, especially
when working with the program material recorded through the
microphone. In many cases this allows one to solve various
phasing problems arising from the microphone placement chosen
during tracking session. In other cases this process may help
one to align drums to each other and to align the bass to drums
and vice versa bringing punch and time coherence not attainable
by the time aligning alone.

Another possible use of PHA-979 is for making stereo-field
adjustments. These can be useful both in audio restoration
applications and audio mixing. For example, some synth
instruments may create a `too wide' stereo field which becomes a
problem when the mixed stereo material is later converted to
mono: those `wide' instruments simply disappear. By shifting one
of the stereo channels--during mixing of the original instrument
track--this problem can be resolved.

PHA-979 is a relatively CPU-consumptive plug-in with a
considerable processing delay (latency). This means that this
plug-in is best used with audio host applications which offer a
freeze-like function along with a plug-in delay compensation.
