Dato vs eqMac

Dato has no write-up on Specifiction yet; its figures are above.

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.
