eqMac vs Wavelet

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.

Wavelet is an Android system-wide equalizer for adjusting headphone sound. It includes more than 5,000 prepared AutoEq compensation profiles and a nine-band graphic equalizer with independently adjustable controls. Other tools provide equal-loudness adjustment, bass tuning, virtualization, reverberation, attenuation, limiting, and left-right balance. Users can import their own AutoEq compensation data, with AutoEq.app and Squig.link listed as places to create it. Supported players include YouTube Music, Spotify, Plexamp, Samsung Music, and VLC for Android, although some require extra setup. The documentation lists TIDAL, SoundCloud, Amazon Music, YouTube, and other players without audio-processing support. Bass boost requires Android 9, while experimental enhanced session detection requires Android 10 or later. Wavelet has a free plan; some features use a paid in-app purchase or subscription with no expiry. Its license covers personal, non-commercial use.
