This emulation delivers all the features from the original unit, along with some extras such as an external sidechain input, a 3 band filter and mix knob for quick parallel compression.

Borrowing all core functionalities from the original unit, it adds the ability to fine-tune almost every parameter, from the envelope timing and saturation level to the sidechain high-pass filter and dry/wet mix levels.

ADHD’s Leveling tool allows much more settings than the original LA-2A unit, such as variable ratios, adjustable attack/release times, an high-pass sidechain filter, a drive control and a dry/wet knob.

Sonic Anomaly’s Slax is a vintage compressor emulation loosely inspired by the LA-2A with a rather agressive and dark character which suits perfectly for vocals, drums or guitars.

Our friends at Bedroom Producers Blog just released Dirty LA, a free compression and saturation plugin inspired by the LA2A:⁠ You can choose between compression and limiting mode, blend the Dry and Wet signals to taste for parallel compression, or use BPB’s very own analog-style ‘Dirty’ saturation algorithms to help you add flavor and character to your tracks and tame more dynamic. ⁠

Lotus Sound Audio has dropped LA2-FOX, a free compressor inspired by the legendary LA-2A. While many aim for faithful emulation, LA2-FOX adds its twist, delivering the warmth and musicality of the original with more control over Ratio, Attack, and Release, giving you flexibility in shaping your sound.
