Versatile new limiter plug-in announced

Based in Sheffield, UK, fedDSP offer a range of plug-ins that span the music production, live sound and high-end media industries. Their latest offering has just been released, delivering a new dual-stage limiter designed to add weight, presence and colour as well as provide detailed control over peaks.

Signals arriving at leONE's input pass through a number of controls designed to alter the character of the sound before any dynamics processing is applied. Before the limiting stages, users are able to introduce some tube- and transformer-inspired saturation, as well as adding some additional low-end resonances and applying lo-fi effects.

The first of its two limiter stages is named Clamp, and is said to be a versatile processor that offers transparent limiting by default, but comes equipped with a Grit control that can be used to push it into more obvious, characterful' territory. The second is designed specifically for level protection, and features a fixed ceiling set at just below 0dB.

In its default view, the plug-in offers a simple set of controls: In, Clamp, Out and Release. Switching to leONE's Advanced panel then reveals an array of more in-depth parameters, including global high-pass and low-pass filters, stereo or dual-mono operation and a Modern/Vintage selector that defines the overall sound character by altering the behaviour of each of the plug-in's processing stages.

Key Features

Dual-stage limiter designed for creative loudness maximisation and reliable peak control.

Colour stage with low-end enhancement, clarity boost, tube/transformer saturation, and lo-fi-type filtering designed to add weight, presence and colour before splitting peak control across two flexible stages.

Primary limiter, Clamp, with variable release and selectable vintage-style limiting mode.

Bypassable ultra-clean safety limiter, with two preset characters: Safe (smooth) and Aggro (aggressive).

Variable high-and low-pass filters.

Extremely low CPU footprint allows for high instance counts, even across large sessions.

fedDSP workflow features including offline licensing, extensive keyboard shortcuts and global Mix knob for parallel processing.

Compatibility leONE is supported on PCs running Windows 10 or higher, and Macs running macOS 10.13 or above. VST3, AU and AAX plug-in versions are available.

Pricing & Availability leONE is available now, and is being offered at an introductory price of £30 until 21 May, when it will increase to £50. Prices include VAT.
