PC Equalizer vs Radioform

PC Equalizer Pro is Windows software for customizing computer audio output and accessing Equalizer APO features. It offers a 10- or 20-band equalizer across all channels, with controls for Stereo, Mono, Swap, Invert, and Balance. Pan/Expand can widen or narrow the stereo image, while Multi-Delays creates echoes, delay, and reverb with up to 16 taps. Users can select built-in presets or save and delete their own, then assign presets to applications such as Winamp, Windows Media Player, and PotPlayer. The program can detect active audio players and load their assigned presets. It can also launch at startup, minimize to the System Tray, and notify users when an assigned preset changes. Equalizer APO setup is included in the PC Equalizer 2.1 installer; manual installation is suggested if PC Equalizer does not run properly. A free demo requires no license key, and the site lists a lifetime license for 3 PCs at 201700.00 USD once. Pricing is also shown as from $20, and a free trial is offered.

Radioform is a free, open-source system-wide equalizer for macOS. It routes audio from Mac applications through a virtual output device and EQ engine to selected speakers or headphones. The equalizer provides ten bands from 32 Hz to 16 kHz, with adjustable gain and Q. Built-in presets cover Electronic, Acoustic, Classical, Hip-Hop, Pop, R&B, Rock, and Flat, and users can save named curves for particular headphones. A limiter and preamp are included to catch clipping when EQ is pushed hard. Radioform switches output devices without restarting and keeps equalization active after the change. It requires macOS 13.0 Ventura or later and runs on Apple Silicon and Intel Macs. The maker reports under 1% CPU usage on Apple Silicon and no audible delay. Releases are Apple-signed and notarized, with updates delivered through Sparkle. The maker says no data is collected. Radioform is licensed under GPLv3; its audio engine uses C++, while the native Swift and SwiftUI menu bar app uses macOS CoreAudio.
