Available for download, the PSPAudioWare PSP McQ is an equalizer plug-in designed for mixing in a pro-audio context. This EQ is modeled on various hardware units such as the venerated MCI console EQ. However, the software goes beyond its inspirations to give you adjustable high- and low-pass filters, optional bell filters for the low and high bands, and three bandwidth settings for the midrange filters.

In the three midrange bands, the gain follows the Q, so that the bandwidth grows narrower and steeper as you adjust the amplitude of the filter. This behavior is quite musical in nature, and allows you to EQ individual tracks assiduously within the mix for greater clarity and separation among instruments.

PSP McQ also features a saturation option in the output section, labeled SAT in the GUI. This feature adds a smooth overdriven character when pushed. Its ceiling is set to a fraction below 0 dBFS to protect against digital clipping.

This software is compatible with Mac and Windows platforms. It will operate in AU, VST, AAX, and RTAS formats.
