Available for download, PSPAudioWare PSP RetroQ is an equalizer designed for use in pro-audio mixing. It's not an exacting, sculpting EQ, as much as it is a broad, sweetening equalizer.
With high- and low-shelving filters based on the renowned PSP VintageWarmer, the EQ provides broad musical boosts and cuts. A midrange section is also provided, using the same digital architecture as the PSP VintageWarmer. An adjustable high-pass filter lets you filter out the low end. Though the plug-in works quite well on submixes and the stereo bus, it will sound musical and sweet on individual tracks as well.
