<p>A system for converting and encoding an analog signal to a digital format and subsequently decoding and converting said digital format to recover the analog signal, comprising means for monitoring the physical characteristics of an analog waveform to be converted to a digital format, means for frequency resolution enhancement to facilitate enhanced playback, means for converting said analog waveform to said digital format, means for encoding within said digital format control information indicative of the physical characteristics of said analog waveform, whereby said analog waveform can subsequently be more accurately reconstructed from said digital format, means for decoding from said digital format said control information indicative of certain specified physical characteristics of said analog waveform, means for converting said digital format signal to said analog waveform, and means for introducing compatible signal reconstruction compensation, in accordance with said control information during said converting process, said information facilitating subsequent more accurate reconstruction of said analog waveform from said digital format.</p> |
