EQBase vs PC Equalizer

EQBase is a system-wide macOS equalizer that processes sound from apps in real time. It includes a 10-band EQ and measured correction profiles for more than 8,600 headphone models. The free tier has no time limit and can record system audio in MP3, AAC, ALAC, FLAC, WAV, or AIFF. Pro adds microphone-based room measurement and a fitted parametric correction curve, per-app volume, mute and tone controls, and routing audio sources to one or more outputs. Pro also supports Audio Unit plugins. EQBase uses headphone correction curves from the open-source AutoEQ project. Audio is processed locally; the privacy policy says audio content, recordings, and listening information are not collected, stored, or transmitted. Normal setup does not install a driver, while optional Audiophile mode and Pro routing use a user-space Core Audio driver. It requires macOS 14.4 or later and supports Apple silicon and Intel Macs. Pro Monthly costs $4.99 per month for three Macs; Pro Annual is $39.99 per year for three Macs, and Pro Lifetime costs $79.99 once for one Mac.

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.
