Astra Creative Audio A-2Bus

A-2Bus is a bus compressor with parallel compression built into the plug-in itself, so the glue and the dry signal are balanced in one place instead of across two channels.

Its threshold does not drift: raising the input by a given amount and lowering the threshold by the same amount land within 0.000 dB of each other, so what you set is what you get.

It is part of the Astra Sampler FX subscription, together with the A-2A and the A-3A. We measure on a bench that ships with the project and we publish the method, including the figures that do not flatter us.
