Blue Cat Audio: Gain Suite

A free suite of gain utility plugins.


8 December 2023

With a background in industrial software engineering, Blue Cat Audio’s founder Guillaume Jeulin understands the importance of stable software. The French company offers professional audio effects, innovative audio analysis tools, and standalone applications that transform Digital Audio Workstations into professional audio processing environments. As an extra arrow in Blue Cat’s quiver, it also offers consulting and engineering services for custom software development, and as such has amassed a variety of customers, ranging from recording studios, universities and recording schools, and home studio owners, to recording engineers, and professional and amateur musicians.

This plugin suite is a series of gain utilities that let the user control the volume of one or several audio tracks simultaneously, in real time. The Gain Suite bundle includes features such as advanced automation MIDI control capabilities, where all response curves can be fully customised. Used together with one of Blue Cat’s analysis tools or a MIDI controller, these plugins let you remotely control and automate the gain of each channel of the audio signal, wherever they reside in the signal path.

Another interesting and exclusive feature is the ability to link several instances of the same plugin, where the unique data sharing technology allows control of the gain of several tracks at the same time with a single slider. The package provides both single channel (mono or stereo) and dual channel versions with mid/side capabilities for independent control of the left and right or mid and side channels, which can be very useful for stereo widening/narrowing of stereo tracks.

  • Single or dual channels gain plugins
  • Stereo or mid-side processing
  • Multiple instances linking capability: link several instances of the same plugin and control several plugins from a single user interface
  • Relative, absolute or reverse link
