PRIVACY AND OPERATION Audio is analyzed locally in Chrome and is not uploaded. The extension stores only measurement values and session metadata on your device. Measurement starts only after you click the extension button or use its keyboard shortcut. The source player is measured at 100% volume, while monitor level is handled separately and restored when measurement stops. IMPORTANT LIMITS This extension measures decoded tab audio. It cannot measure operating-system volume, sound-driver processing, DAC output, or speakers. Loudness Console for YouTube is an independent open-source project. It is not affiliated with or endorsed by YouTube or Google. Created by Lee Soda with AI-assisted development.
