Spectrum Analyzer
Added 2024-10-01 12:24:55 +0000 UTCI'm not sure if anyone is interested in this. I took Cursor IDE for a spin and decided to code a small spectrum analyzer in the browser.
You can allow the browser to use any input (here I'm using the loopback device of my audio card). You can see peaks and average for the spectrum, and there is a threshold you can change to show labels for frequency and notes for the loudest frequency peaks. You can change the color and the RMS window, or the weighting of the spectrum.
Everything is done in HTML, CSS, and vanilla JS — no libraries or frameworks are used.
