SONALKSIS SV-517 EQUALISER

Description:

GSnap is an auto-tune effect. It can be used subtly
to correct the pitch of a vocal, or, with more extreme settings, to
create a robot-voice effect.

For GSnap to work effectively,
the input signal should be monophonic, at a good level and reasonably
noise-free. For example, a clean, mono vocal recording, without
excessive noise or reverb. Effect plug-ins should be placed after GSnap
in the signal chain.

GSnap starts off by detecting the pitch
of the incoming audio. The Min Freq and Max Freq parameters help the
pitch-detector by narrowing the range of frequencies it needs to
consider. Also, the Gate parameter should be set so that the
pitch-detector ignores background noise during "silent" passages.

The
Speed parameter sets the number of wave repetitions required for
positive pitch-detection. Lower values for Speed will allow faster
pitch-detection, but will increase the chance of false detection. The
default value should be fine in most cases.

Once a pitch has
been determined, GSnap applies the specified pitch-correction. There
are two modes of pitch correction: fixed scale and MIDI. Fixed scale
correction has a fixed set of snap-notes, while MIDI correction is
controlled in real time by MIDI data.

The Threshold parameter
sets the largest pitch-shift that will be applied to the input. It
defines a region around each snap-note that will be corrected to that
note. The GUI shows the snap-notes and regions in effect at any time.

The
pitch-detection and correction can be made to use a different reference
frequency using the Calibrate parameter. This sets the frequency of A
above middle C.

Additionally, GSnap will respond to pitch-bend
and modulation MIDI messages to apply pitch-bend and vibrato. The Pitch
Bend, Vibrato and Vib Speed parameters control these effects.
