digital and analog signals

The machine is a Studer. The tape is open-reel and magnetic. Press play, the tape runs along the two tape heads and voila – the audio can be heard. Magnetic particles on the tape are arranged and aligned by the heads to create an analog audio signal.

125,000 hours of NPR stories were recorded on open-reel tape. This format is obsolete, and is at risk of degradation. NPR RAD is firing up our Studers, playing the tape, and converting the analog signals to digital in order to save our stories!
