Contra is a powerful plugin designed to enhance your mixing decisions by allowing you to focus solely on listening. It enables seamless comparison of multiple audio plugins without the distraction of manual switching or monitoring cursor movements. Featuring automatic cycling through your selected plugins, Contra removes the need for keyboard or mouse interaction, so you can trust your ears without interruption. Its internal auto gain matching ensures that volume differences do not bias your judgment, providing an accurate and neutral listening experience.

With support for up to eight plugins, Contra accommodates AU, VST, and VST3 formats, giving you access to each plugin's interface and parameters during comparisons. You can mute or bypass individual plugins to focus on specific options, making it easier to narrow down your choices. The plugin also allows setting the duration for which each plugin is audible, enabling consistent comparisons over the same audio segment. This functionality extends to comparing processors across different tracks or signal chains, streamlining your workflow and helping you achieve better mixes more efficiently.

Contra supports saving complete setups as presets, including all plugin parameter settings, so you can quickly load your preferred configurations for different instruments or mixing tasks. This feature promotes a more organized and effective workflow, helping you make informed decisions from the start of your session. Its low CPU and memory usage, combined with compatibility across various DAWs, make Contra a valuable tool for anyone looking to optimize their mixing process through focused and unbiased plugin comparisons.
