Abstract :
A new "two-track" technique extends the weighted dynamic range of audio tape systems to at least 76 dB below three percent Third Harmonic Distortion. Simplest techniques are employed during recording. The extended range is achieved by continuous automatic selection of the optimum track for minimum distortion or quietest background during playback.
