What's New in FET Acoustic Compressor
1.1.0
September 8, 2026
Fixed: driving the input harder now gives you more compression, not less In 1.0.1, gain reduction stopped increasing at around −3 dBFS input and then started falling — so pushing the IN knob past that point actually gave you *less* compression. Since this compressor is built to be driven hard, that was easy to run into. It is fixed. This brings back the 1.0.0 sound Version 1.0.0 had this right. The problem was introduced by a performance optimization in 1.0.1, and 1.1.0 restores the original behavior while keeping the CPU improvements. Heads up on your presets If you saved presets in 1.0.1 with the IN knob pushed up, they will compress noticeably harder now — that's the plugin doing what it always should have. You may want to give those a quick check. Presets at lower input settings are unaffected.
