Modifications are described which convert an inexpensive ‘Digital Audio Processor’ (Sony PCM-701ES), together with a video cassette recorder, into a high performance digital tape recorder, with two analog channels of 16 bit resolution and DC-20 kHz bandwidth. A further modification is described which optionally provides four additional 1-bit digital channels by sacrificing the least significant four bits of one analog channel. If required two additional high quality analog channels may be obtained by use of one of the new video cassette recorders (such as the Sony SL-HF100) which incorporate a pair of FM tracks.
