Free EQ launched alongside four major updates
PSPaudioware have just launched their latest free plug-in, along with a set of updates that bring modern OS compatibility and an assortment of new features to four of their existing EQ offerings.
PSP ClassicQlite is a completely free version of PSP ClassicQ, an easy-to-use plug-in that's based on the circuitry found in early Neve designs. It features low- and high-frequency shelving filters equipped with switchable Q settings, and combines them with a midrange bell filter that offers both a selectable Q and an Auto Q function. In addition to its EQ capabilities, the plug-in offers some analogue-style distortion courtesy of PSP's SATuration algorithm.
Key Features
Musical low- and high-frequency shelving filters with switchable Q settings.
Adjustable high-pass filter.
Flexible midrange bell filter with selectable Q and Auto Q.
PSPs second-generation SATuration algorithm for smooth, analogue-style overdrive.
Modern preset management, A/B comparison and a resizable interface.
Updated EQs Alongside the new arrival, PSPaudioware have also released updates for four of their existing EQ plug-ins: PSP McQ, which draws its inspiration from the EQ section found in classic MCI consoles; PSP RetroQ, a gentle-sounding EQ that employs filters based on those found in PSP VintageWarmer; and the British console-style PSP ClassicQ / PSP ClassicQex. Thanks to the updates, all four plug-ins now support modern Windows and macOS systems and include a selection of enhanced features.
Compatibility PSP ClassicQlite is supported on PCs running Windows 10 or later, and Macs running macOS 10.14 and above. VST, VST3, AU and AAX plug-in versions are available.
Availability PSP ClassicQlite is available now, and is free to download. PSPaudioware are also offering the following discounted prices on their other, updated EQ plug-ins until 21 November 2026:
PSP McQ: $29 (usually $69)
PSP RetroQ: $29 (usually $69)
PSP ClassicQ (includes PSP ClassicQex): $29 (usually $69)
