Pragmatic Audio PEQ
KONECKTA LIMITED
Pragmatic EQ is a parametric equaliser for iPhone and iPad. On iOS 27 or later, select its virtual audio output in Control Center to stream audio from compatible music players through your EQ. CORRECT YOUR HEADPHONES • Browse measurement databases and OPRA community presets to find EQ profiles for your headphones or in-ear monitors. • Import Filters.txt profiles, including separate left and right filter files. • Edit individual parametric bands, shape bass and treble, or use a fixed-band editor. • Save personalised profiles and adjust headroom or set the preamp manually. HEAR THE DIFFERENCE • Compare No PEQ and PEQ while music plays, with optional volume matching and blind A/B comparisons. • Experiment with crossfeed, tube, vinyl and other effects. SEE WHAT YOU HEAR • Live visualisations include spectrum bars, EQ graphs, a spectrogram, level meters, VU meters and a colour spiral. • Visualisations run while their view is active. CHOOSE YOUR LAYOUT • Keep the scrollable one-page layout or switch to tabs in Settings. • A Welcome guide explains how to connect music, load a profile and create your own. • Choose light, dark or system appearance and your interface language. • Optional audio recovery reminders help you reopen the app when needed. PRIVATE BY DESIGN No account, ads or tracking. Audio is processed locally and is not recorded, stored or transmitted. The microphone is never used. REQUIREMENTS AND PLAYBACK LIMITATIONS iOS/iPadOS 27 or later is required for the virtual audio output. Open the app, start music in a compatible player, then select Pragmatic EQ in Control Center. Some players and video modes do not support this route. If iOS returns to your previous output, reopen the app and select Pragmatic EQ again. Pragmatic EQ builds on open source work, including EffectDeck and EffeTune (MIT licence) and the OPRA preset database (CC BY-SA). See About in the app for credits and licences.
