01Overview

A-Class Vocal is based on a custom-modified Dolby-A unit taken from the studio of a Swedish songwriter. The plugin focuses on one effect: a smooth, lifted top end that the developer describes as a studio technique that has been used on vocal chains for decades. Bogren Digital describes the processing as a mix of tone shaping and dynamics, rather than straightforward EQ. The plugin is sold as an effect for vocals and can also be applied to other sources in a mix.

03In depth

Sound and Character of the Dolby-A Sheen

The developer explains that the effect comes from running the Dolby-A noise-reduction process without its decoding stage. The result is a blend of tone shaping and dynamics that smooths and raises the top end of a signal.

Bogren Digital says the plugin captures the character of the original hardware unit. The aim is a vintage-style sheen without the need to work with the hardware itself.

The controls are intentionally limited, so the character comes mostly from the processing rather than from a large number of settings.

Controls and Workflow in A-Class Vocal

The plugin has three main controls. DRIVE sets the amount of sheen. MIX blends the effect in subtly or pushes it forward. MOD selects an alternative version with additional, richer harmonics.

MOD can also be used as a glue-style stage, which the developer says can replace a large part of a vocal chain.

Because the controls are few, the plugin is quick to set up. Start with the vocal, then try it on other sources such as acoustic guitar, overheads, synths or the mix bus when the track needs more air.
