Key Features

  • Four virtual doubling voices can be arranged across a stereo sound stage for a broader image.

  • Tone applies tilt EQ to the doubled layer, while Frequency Range focuses the effect on a selected band of the source.
  • Dry-signal control supports both insert processing and send-style effect setups with transient-based ducking.
  • Mid/side processing balances the added stereo effect between the center and sides of stereo material.
  • An automation-oriented on/off switch is designed to avoid clicks when changing the effect state.
  • The interface scales from 80% to 150% for different display sizes.

Description

S Doubler is a four-voice doubling and stereo-imaging effect from SoliderSound for giving vocals and instruments more width, depth, and apparent placement. Its virtual sound stage spreads the added voices around the stereo field, so a mono source can take on a broader, more layered role without recording additional takes.

Spread changes the width and variation between doubled voices, while Distance controls their perceived proximity. Tone applies a tilt EQ to the added voices, Frequency Range limits where the effect operates, and Level adjusts the doubled signal without changing the original signal's level.

The effect can retain the dry signal for insert use or mute it for a send-style setup; with the dry output active, the plugin uses transient-based ducking on the doubled voices. Mid/side processing lets you balance the effect across the center and sides of a stereo track, and the built-in bypass is intended for click-free automation.

That makes S Doubler a practical fit for subtle vocal reinforcement, wider backing parts, larger guitars or synths, and creative chorus- or ensemble-like movement. The developer also lists it for making stereo signals from mono sources and for adding size to complete mixes or live-performance material.

Frequently Asked Questions

What does S Doubler do?

S Doubler creates four added voices around a virtual stereo stage to add width and depth to a source. It is designed for vocals and instruments, and the developer also lists mono-to-stereo conversion among its uses.

Can I use S Doubler on an effects send?

Yes. The Enable Dry Signal control can mute the original audio for a send-style workflow. With the dry output enabled, the plugin applies transient-based ducking to the doubled voices.

How can I keep the widening focused?

Use Frequency Range to limit the doubling effect to a chosen part of the spectrum. Tone shapes the doubled voices with tilt EQ, and mid/side processing lets you balance the effect across a stereo track's center and sides.
