Whether you use a traditional de-esser,
sidechained compressor, dynamic EQ, or even edit
your tracks manually, cleaning up sibilance problems
in your vocals can get pretty tedious. Lisp is new
type of de-esser that aims to speed-up this process
with its automatic sibilance detection algorithm.
Internally tuned to the human vocal
range, Lisp can automatically detect and lower
annoying "ss", "teh", and "ch" sounds in your audio
by tracking both the amplitude and pitch of its
input in real-time. Just set the reduction amount
and let Lisp do the rest!
Lisp's internal algorithm doesn't
rely on traditional threshold/frequency-based
techniques found in most current de-essing systems.
Instead, it uses a modified form of the Sleepy-Time
Records transient detection algorithm (previously
found in the KVR-DC2012 entry: Transient) coupled
with fast frequency detection and phase-cancellation
methods to remove unwanted sibilance, regardless of
the input level. The result is a very natural and
pleasing vocal with harsh "s" sounds under control
no matter what distance the singer is in relation to
the microphone. Not only that, but the entire
process is highly CPU efficient, allowing you to use
more instances in your project.
Lisp is available for Microsoft®
Windows® 32-bit and 64-bit systems in the VST2 and
Lisp is available for free.
