Spectrogram: An Agentic Coding Side Quest Into Final Cut Pro Audio Analysis
Post Views: 27 If you already live and breathe audio analysis, feel free to skip this bit and go straight to the tale of plugin architecture, notarization and mild host-induced despair.

BUT, I had to be connected to the sniffer over a serial interface and that was becoming…
