EQuivocate

Elevate is the most advanced mastering plug-in ever created. This unique multi-band limiter, human-ear EQ, and powerful audio maximizer will increase the loudness of your mix while maintaining or improving its dynamic perception. It uses intelligent, adaptive technology that responds in real-time to your music, creating not only the loudest but the best-sounding master. Developed by Newfangled Audio, Elevate maintains subtle dynamics and improves the tonal balance of your mix. The adaptive limiter analyzes 26 frequency bands and alters the gain, speed, and transients for each band in real-time. The result is a transparent, natural sound, no matter how hard you push it. Elevate utilizes 26 critical filter bands modeled from the human ear. Each of the bands is spaced to give maximum control over how the sound hits your eardrum. Draw curves, solo bands and manipulate the transient attack for each individual band to bring out particular instruments such as kick or snare drums.

EQBase is a native macOS app that puts an equalizer and a full set of audio controls in front of everything the Mac plays: browsers, calls, games, and system sounds, all at once. It ranges from a simple 3-control EQ to a 24-band parametric with dynamic and linear-phase filters, and includes correction curves for 8,666 measured headphone models, per-app volume and per-app EQ, per-app output routing, Audio Unit hosting, system audio recording, room measurement, and loudness compensation. It adds zero latency to the direct signal, and when every control is flat the output is bit-perfect, verified continuously against the live audio. Setup needs one system permission: no admin password and no kernel extension by default. The free tier has no time limit. Pro adds the advanced tools for $4.99/month, $39.99/year, or $79.99 once, with a 14-day refund. Requires macOS 14 or later, Apple silicon and Intel.
