CLUSTER AUDIO-EQUALIZER-CORRECTION · 16 ENTRIES · EARLIEST ENTRY 2026-05-31

macOS system audio equalizers

These products form a cluster of macOS utilities that apply system-wide audio processing, primarily parametric equalization, with features like presets, headphone correction curves, and per-app volume control. The dated history shows two entries in late 2022 and early 2023, then a hiatus, followed by three entries in spring and summer 2026, indicating the cluster has existed for several years with sporadic additions before the index start. Traction leaders are SoundstageIRGenerator and openspatial (both 3 stars), followed by tapline (2 stars).

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 16 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
