CLUSTER AUDIO-REAL-SPECTRUM · 7 ENTRIES · EARLIEST ENTRY 2024-04-11

Terminal audio analyzers

This cluster comprises command-line tools for real-time audio visualization and measurement, including spectrum analyzers, oscilloscopes, and tone generators. The cluster's dated history is too thin to read a shape from -- only four dated entries exist prior to the index start, and they exhibit no clear trend. The traction leaders, spectroterm, scope-tui, and spectrust, each show zero 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 7 listed below. Unlabelled means nothing has decided yet — not that the answer is small.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
