While de-essers and dynamic EQs can be very useful, they are rarely sufficient for effectively managing sibilance in vocal recordings. Producers and engineers alike commonly find themselves spending long hours manually editing these problematic sounds. While often unavoidable, this method is very time-consuming and diverts attention from what really matters.

Key features

• Sibilance splitting: The core function is splitting the audio signal into its sibilant and non-sibilant components. If you don't apply any changes, the recombined signal is perfectly identical to the original.
• Linear gain control: You get independent volume faders to control the level of the sibilant and non-sibilant components. This allows for precise, simple volume automation on only the harsh "s" sounds.
• Advanced detection: The plugin uses a combination of input level, pitch detection, and spectral brightness analysis to accurately identify sibilance.
• Signal integrity: The splitting process happens at the full frequency range without adding compression, EQ, or crossovers, which can otherwise introduce unwanted artifacts.
• Solo functionality: You can solo either the sibilant ("S") or non-sibilant ("non-S") components to hear exactly what is being separated, allowing for more precise adjustments.
• Real-time visualization: A scrolling waveform display provides a visual representation of the audio, showing where the plugin is detecting and processing sibilance in real time.
• S-Range control: This feature allows you to control the gain of individual sibilant events based on their peak level. You can use it to set a maximum volume for "S" events or exclude quieter ones from processing.
• High-quality crossfades: The audio is separated and re-mixed using high-quality cosine-based crossfades to ensure smooth and natural transitions. 

• Processing method: A de-esser uses dynamic compression, which can sometimes color the sound or cause pumping artifacts. splitS uses a linear gain change, which is more transparent.
• Control: A de-esser's controls are focused on the threshold and amount of compression. splitS gives you a simple mixer for the sibilant and non-sibilant parts, similar to doing manual volume automation.
• Flexibility: Because splitS isolates the sibilant and non-sibilant parts into two separate channels, you can apply other processing to them individually. For example, you can add different EQ to only the sibilant sounds.
