FIELD: computer engineering; recording and reproducing analog signals by means of nonvolatile memory. SUBSTANCE: device available in more than one design alternates has interface for interpreting peripheral instructions, control means, analog-to-digital and digital-to-analog signal conversion means, memory, multiplexer, audio filter, and demultiplexer. Method proposed in more than one alternatives involves memory division into plurality of sectors and generation of data byte read-out instruction; in the process current memory sector is identified as null sector in case of zero bytes and as message sector when bytes are other than zero. EFFECT: simplified user s interface. 18 cl, 6 dwg, 1 tbl
