Abstract

A prototype multitrack digital audio recorder is described. Two audio channels are sampled and coded by 14-bit linear quantization. The sampling rate is 44.1 kHz, the tape speed is 95 mm/s, and the tape width is 6.35 mm. the channel code (a dc-free block code) makes use of the statistics of the audio signal. Precautions are taken to limit the crosstalk in the 16-track ferrite head stack. Error correction and concealment techniques are applied to compensate for random and burst errors.
