Quick Haas is a free psychoacoustic panning plugin designed to enhance stereo imaging by leveraging the Haas effect, also known as the precedence effect. This auditory phenomenon enables listeners to perceive the spatial position of an audio signal based on minimal timing differences between the left and right channels. By introducing subtle delays, Quick Haas creates a more natural and immersive panning experience compared to conventional methods, making it ideal for stereo playback systems.

The plugin is straightforward and intuitive, catering to users who want to add depth and direction to their sound without complex settings. When processing stereo inputs, users can select the routing of the audio channels, with a recommendation to use one channel or a mono source if the original stereo channels differ significantly. The central control knob adjusts the delay between channels, allowing the sound to be positioned precisely within the stereo field.

Quick Haas offers extremely fine control over delay times, with adjustments possible down to a tenth of a millisecond. Typically, very small delay values under 2 milliseconds suffice to create a powerful and realistic spatial effect. This makes it a valuable tool for producers and engineers seeking to enrich their mixes with subtle yet impactful stereo imaging enhancements.
