Linux Studio Plugins Project LSP Deesser

This plugin enables targeted attenuation of sibilant, hissing, and high-frequency harshness in the audio signal. It features an integrated sidechain equalizer with sweepable center frequencies and adjustable bandwidth, allowing high-precision focus on specific problem areas while filtering out unwanted low and high frequencies. With controls for sensitivity threshold, threshold detection, and frequency-dependent visual metering, it ensures optimal vocal clarity and overall spectral balance.
