This piece details Samy Kamkar’s enhancements to laser microphone eavesdropping, using a strobing infrared laser modulated at 400 kHz, RF upconversion, and software-defined radio to extract cleaner signals that can reconstruct room audio and infer keystrokes; the workflow incorporates noise reduction (iZotope RX) and Keytap3 to translate keystroke sounds into text, with noted limitations such as reduced effectiveness through double-paned glass.
