CLUSTER AUDIO-MUSIC-ANALYSIS · 15 ENTRIES · EARLIEST ENTRY 2020-05-31
Music and audio analysis libraries
This cluster consists of software libraries and toolkits for music and audio analysis, including DSP functions, music information retrieval frameworks, and metadata querying tools. The dated entries span from October 2015 to June 2026, appearing roughly once a year with occasional consecutive months, indicating a low-frequency stream of such tools. The leading members by activity signal are python-music21, silent-room, and sz0mtify, all currently at 0 stars.
Entry timeline
ENTRY TIMELINE
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 15 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
