Analog Obsession BUSTER v7.0 VST VST3 AU WiN MAC [FREE]

Analog Obsession BUSTER v7.0 is a free bus compressor for producers who want to manage dynamics across grouped tracks or a full mix. It suits home-studio musicians working with drums, layered instruments, and other material that benefits from shared compression.

BUSTER offers six attack settings from 0.1 to 30 ms and five fixed release times from 0.1 to 1.6 seconds, plus an Auto option. Six ratios, ranging from 1.5:1 to 10:1, let you choose between lighter compression and firmer control. Threshold and makeup gain both cover -20 to +20 dB, while the dry/wet mix control makes parallel compression possible within the plugin.

A sidechain high-pass filter spans 20–500 Hz, helping reduce how strongly low frequencies trigger compression. External sidechain support lets another signal drive the compressor, and a general bypass switch allows quick comparisons with the untreated audio.

Version 7.0 updates the interface and refines attack, release, and sidechain response, including improvements to mono instances in Logic Pro X. For Ableton Live on macOS, the developer specifies using the VST version.
