Developer yg331 has launched Aid Compressor and Aid EQ, a pair of free mixing plugins out there in VST3 and AU codecs for Home windows and macOS.
These are the primary releases from yg331, an impartial developer who’s enthusiastic about mixing and DSP design (a beautiful mixture of pursuits that usually leads to some good plugins for us common individuals).
Each plugins are constructed with double-precision 64-bit processing, and the first function behind their design was to supply dependable instruments for each day mixing and mastering duties.
Aid Compressor
Aid Compressor is a versatile dynamics processor appropriate for every part from mild bus compression to tighter track-level management.
It presents a number of detector choices (Peak, RMS, Linear, Logarithmic, and even a Hilbert-based detector). Clearly, every has its personal sonic traits, so it’s like getting 5 compressors in a single.
The Logarithmic detector, for instance, excels at peak management with exact assault timing, whereas the Linear mode feels punchier and extra open.
You additionally get a hard and fast 0.5ms lookahead powered by a Kaiser-Bessel FIR filter, which helps catch quick transients cleanly.
I additionally like that there’s a devoted sidechain EQ part, providing a two-band EQ with selectable filters and cabinets. This allows you to form the sidechain sign with surgical precision.
With all of those options packed into its unassuming, nearly scientific-looking interface, Aid Compressor seems like a Swiss Military knife for dealing with most compression duties. I like it.
Aid EQ
Aid EQ follows related ideas. It’s an excellent versatile digital equalizer designed for transparency and musical operation.
Just like the compressor, it runs completely in double-precision and upscales to 88.2 or 96 kHz for inner processing when working at 44.1 or 48 kHz. This minimizes cramping artifacts, particularly within the excessive finish, and retains the EQ curves sounding extra analog-like.
The developer delves deeply into the design philosophy behind the EQ. The whole lot, from filter topology to oversampling selections, is taken into account rigorously.
Aid EQ goals to strike the right stability between scientific accuracy and musical really feel. The refined design choices, like shelf filter shapes and Achieve-Q dependencies, give it a pure response that makes it extra intuitive to make use of.
Free Obtain
Each plugins are thoughtfully designed and well-documented on the developer’s GitHub, the place you may as well obtain them without spending a dime.
No registration, activation, or installers are required. Simply seize the recordsdata and drop them into your plugin folder.
