Acustica Audio makes some great stuff and they’ve got three plugins available for free.
Tan Free Compressor
“Acustica is pleased to introduce TAN Compressor based on CORE8 with a classic analog VCA compression. It’s a very versatile tool to provide a lot of possibilities to shape the sound with gorgeous graphical user interface.”
“In this plug-in you will of course find the most common parameters like attack, release, threshold, ratio, dry/wet and gain, to allow an extremely wide range of adjustments. One of the exciting new features that is new to software is what we call “ShMod”. This is a shape control for the attack behavior of the compressor. It allows you to fine-tune the attack shape so you can really customize the attack behavior for any audio source!”
Red Free Equaliser
“The Red Eq equalizer provides three fixed bands at 80Hz, 1.8kHz and 8kHz, the upper and lower bands being shelving while the middle has a traditional bell response. There’s an ample 16dB of cut and boost, and though the EQ may look limited compared to a parametric, it actually sounds nicely musical and the frequencies have been chosen with care. A five-section led level meter and an output gain knob allow you to control the overall output level from the unit up to a maximum of +6dB. A red warning lamp lights if the signal approaches clipping, due to excessive use of boost on already hot signals. It can be used to make adjustments in the most needed areas of the audio spectrum without the sound losing its focus.”
Ochre Free EQ
“Acustica is pleased to introduce Ochre “HOMEBREW” Eq, an EQ with 3 parametric bands, individually switchable; It’s the first plug-in of the HOMEBREW series, a new series of Acqua plug-ins with gorgeous graphical user interfaces that enable easy and quick parameter changes.”
