%description
Chameleon is a guitar plugin using neural networks to create
three distinct sounds from a vintage style amp head. EQ and
gain were added to allow further modification of the three
core sounds, named Red (high gain), Gold (crunchy), and Green
(crisp and clean). In the same way a real amp head is used
with a cabinet and other effects, this plugin is intended to
be used in the signal chain along with IR's (cab sim), reverb,
and any number of guitar effects.

Chameleon's core sound comes from a neural net inference engine
which allows the plugin to disguise itself as a high end tube
amplifier. The engine uses a stateful LSTM model, which improves
the sound quality of the previous stateless LSTM used in the
SmartAmpPro. It also improves CPU usage compared to the
SmartAmpPro and SmartGuitarAmp.
