Free BPB Dirty VHS VST Plugin

Dirty VHS is a free plugin that brings back the dodgy sound of old VCRs and video tapes.

Bedroom Producers Blog has released BPB Dirty VHS, a free plugin concerned with audio only.

Specifically, the kind of imperfect sound you used to get from old video cassette recorders and the VHS tapes that you put into them (unless you were a Betamax user – in which case, you’re probably sitting there now saying that it was actually the better format and that this plugin should really be called Dirty Betamax).

BPB says that the new plugin was “born out of our love for resampling audio for VHS and the need to streamline the process and make it more instantaneous.” It’s based on analysis of multiple VCRs and tapes in varying states of repair, with the pitch variation, circuit and transport noise, dynamics, and frequency response information being extracted from each unit.

Accordingly, the eight processing modes emulate various machine/tape combinations in different conditions. You also get the sound of a VCR accidentally being switched into long play mode, a circuit-bent model and a vintage games console being recorded to VHS.

There are also three processing modes: Grainy is the most accurate but the hardest on the CPU; Smooth is less precise and less demanding on your CPU but preserves transients better; and Whammy turns Dirty VHS into a pitch shifter.

Other features include a tape chorus with stereo spread – designed to emulate the sound of a signal being recorded to multiple VHS tapes – and the distortion algorithm from Dirt, another of BPB’s free plugins.

Dirty VHS comes with 20 presets and offers a freely resizable GUI, a randomise button and undo/redo functionality. You can download it for PC and Mac in VST/AU formats from the Bedroom Producers Blog website.
