Also, the entire procedure is extremely CPU efficient, allowing you to have more instances in your project. No matter how far away the vocalist is from the microphone, the outcome is a highly natural and pleasant vocal with harsh “s” sounds under control.

Instead, regardless of the input level, it employs a modified version of the Sleepy-Time Records transient detection technique (previously discovered in the KVR-DC2012 entry: Transient) in combination with rapid frequency detection and phase-cancellation approaches to eliminate undesired sibilance. Most contemporary de-essing systems rely on threshold/frequency-based methods, while Lisp's internal mechanism does not. Simply set the reduction amount and Lisp will take care of the rest! To speed up this procedure, the Lisp De-Esser employs an automated sibilance detecting algorithm.Īs it’s internally tuned to the human voice range, it can identify and reduce irritating “ss,” “teh,” and “ch” noises in your audio by measuring the volume and pitch of its input in real time. Sleepy-Time DSP's Lisp is a free De-Esser plugin with a level-independent sibilance processor.
