SSL DeEss is a precision tool designed to tackle sibilance and high-frequency harshness in vocal recordings and instrument tracks. It focuses on reducing problematic 'ess' and 'shh' sounds while maintaining the natural tone of the original audio. This tool enhances workflow efficiency by offering features like automatic auditioning and a built-in brighten control, which helps to restore clarity to the signal after de-essing.

The DeEss plugin employs a relative threshold algorithm that ensures consistent performance regardless of input level changes. This unique approach allows it to handle both subtle and prominent sibilant events with equal effectiveness. Users can also choose to process either the mid or side elements of the stereo signal, providing greater control over the tonal balance. Additional options such as automatic oversampling and lookahead contribute to its high-quality audio response.

SSL DeEss includes a variety of presets tailored for different vocal ranges and instruments, simplifying the setup process for users. Its flexible filtering options allow selection between split and broadband processing modes, with carefully designed gain reduction to ensure transparency and naturalness. Native support for Apple M1 processors guarantees efficient performance on modern systems, making it an essential tool for precise sibilance management and high-frequency control in professional audio production.
