Voice Steady
Plays your cue in your headphones when your voice stays low for a while. Keep this tab open while streaming; it works in the background.
Last 2 minutes. Dots are your pitch while talking; the dashed line is your threshold.
Resonance (F2) while talking. Higher means a brighter, more forward sound. It's rougher than pitch and changes with your mic and with the vowel, so compare it with your own normal voice, not with a fixed number.
Cue when your recent median is below this. Record yourself first (see the README) to pick a number that suits your own voice.
Only colors the resonance number (green at or above it, yellow within 100 Hz, pink below). It never plays a cue. Pick a number between your normal voice and your target voice.
Seconds of actual talking (silence doesn't count) within the last 30 seconds.
The bar is your mic level. Set it so your talking lights it up but background noise doesn't.
Pick your headphones. If only one speaker is listed, Chrome is hiding the rest: in Windows, Settings > System > Sound > Volume mixer, set this browser's output to your headphones. OBS only captures specific apps, so as long as this browser isn't one of them, viewers won't hear it.
Saves only your mic (no game audio) as 5-minute files in the folder you pick, so voice analysis hears just you. About 10-15 MB per hour. If the tab crashes you lose at most the last 5 minutes. Needs Chrome or Edge.
