Read before connecting circuits. Audio Bench drives signals out of your computer’s headphone jack and reads from its mic input. Do not connect any source above ~2 V or any DC voltage. For real measurements use a USB audio interface and a 10:1 attenuator + DC-blocking cap on the input. Measurements include your soundcard’s own response — run loopback calibration to remove it.
