ApulSoft SplitS v1.1.3

Software Overview

---

SplitS is intended for vocal production workflows where sibilant sounds need to be controlled individually rather than processed through a conventional de-esser. The plugin divides the incoming full-range signal into two components: sibilance and non-sibilance. These components can then be balanced directly as part of the editing process.
The detection system analyzes spectral brightness, level, and pitch to identify sibilant events. Because the split is performed across the full frequency range, SplitS does not rely on a crossover or EQ-based separation. The waveform display shows the detected regions and level changes while processing is performed.
The S-Range function adds control over detected S events by allowing users to specify maximum and minimum levels. This can be used to limit stronger sibilances or exclude softer events from the S channel according to the desired editing workflow.
Key Features

---

• Detects sibilance using spectral brightness, signal level, and pitch.
• Separates vocals into full-range sibilance and non-sibilance components.
• Allows direct level balancing of the separated signal components.
• Preserves the original signal when no volume change is applied.
• Processes the split without compression, EQ, or crossover filtering.
• Provides a scrolling waveform display with real-time split and level information.
• Includes S-Range controls for setting minimum and maximum levels for S events.
• Supports multi-output routing for NOS/S signals in Pro Tools, Reaper, Live, and Bitwig.
• Provides optional SoundFlow scripts for automating SplitS workflows in Pro Tools on macOS.
• Supports AudioUnits, AAX, and VST3 plugin formats.
• Runs on 64-bit macOS and Windows systems.
• Provides typical parameter-dependent latency of approximately 30 ms.

Why Choose ApulSoft SplitS

---

SplitS is designed for producers and engineers who need detailed control over vocal sibilance without spending extensive time on manual waveform editing. Its dedicated separation process makes it possible to work with sibilant and non-sibilant material independently while keeping the full-range character of the source signal.
The S-Range controls and multi-output support also make SplitS suitable for more detailed vocal editing and routing workflows in compatible audio production software. SoundFlow integration can further automate its use in Pro Tools on macOS when the available scripts are used.

Frequently Asked Questions

---

Is SplitS a de-esser?

---

No. SplitS is designed as a mixer and signal-splitting processor rather than a conventional de-esser. It separates sibilance from non-sibilance so the two components can be balanced independently.
How does SplitS detect sibilance?

---

The plugin analyzes spectral brightness, signal level, and pitch to identify sibilant events within a vocal recording.
Does SplitS use compression or EQ to separate sibilance?

---

No. The source describes the processing as operating on the full-range signal without compression, EQ, or crossover filtering.
What is the S-Range feature?

---

S-Range allows users to define maximum and minimum levels for detected S events. It can therefore be used to control stronger sibilances or exclude softer events from the S channel.
Which plugin formats does SplitS support?

---

SplitS supports AudioUnits, AAX, and VST3 formats on 64-bit macOS and Windows systems. It also supports multi-output routing in Pro Tools, Reaper, Live, and Bitwig.
