Decode FESK audio transmissions and paste them into text fields

FESKPaste decodes FESK (Frequency Shift Keying) audio transmissions from a Sensor Watch using your microphone and pastes the decoded text into any focused input field. Press F9 or click the extension icon to start listening. The extension detects the transmission, decodes it, and can automatically paste the result, copy it to your clipboard, and close — all hands-free. Features: - Decode 4FSK, BFSK, or hybrid modulation modes - Automatically paste decoded text into the focused input field - Optionally send Enter to submit forms after pasting - Auto-copy to clipboard and auto-close popup - Configurable timeout (10–120 seconds) - Microphone test and permission grant from the settings page - Keyboard shortcut (F9) for quick access - Works on Firefox and Chrome All audio processing happens locally in your browser. No data is collected, stored, or transmitted.
