eqMac vs PC Equalizer

eqMac is a system-wide audio equalizer and volume mixer for macOS. The free tier includes basic bass, mids and treble controls and a fixed 10-band equalizer. AutoEQ provides automatic headphone equalization from frequency responses, with support listed for 4,600 headphone presets. Pro adds unlimited customizable bands, a real-time spectrum analyzer, separate left and right channel EQ, AudioUnit hosting, spatial audio and per-application volume mixing. The maker says its driver captures system audio and passes it to the app through a secure memory tunnel for processing; it also says the driver runs in user space rather than the kernel. Downloads are listed for macOS 10.13 or later on Intel and Apple Silicon. The maker lists a free HTTP API for controlling eqMac, and remote control from iOS, iPadOS or Android devices on the same local network as a Pro feature. The free plan has no Pro features. Paid access is listed from $1/mo, while the Pro subscription page does not state a yearly price. Public GitHub code corresponds to version 1.3.2 without Pro features; newer releases are developed on a private fork.

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.
