57. A method of processing information bearing signals to initially reduce the information content thereof without destroying the intelligibility of the information contained therein and to synthesize signals from the processed signals, said method comprising the steps of: (a) Mozer phase adjusting said information bearing signals to produce equivalent signals having substantially symmetric portions; (b) deleting selected redundant portions of said equivalent signals; (c) X period zeroing said information bearing signals by deleting preselected relatively low power portions of the signals resulting from steps (a) and (b); (d) generating instruction signals specifying those portions of said signals deleted in steps (b) and (c); (e) reproducing the signals resulting from said steps of (a) Mozer phase adjusting, (b) deleting and (c) X period zeroing; (f) expanding said reproduced signals to supply said deleted redundant portions in accordance with said instruction signals; (g) inserting substantially constant amplitude signals between the non-deleted portions of the signals resulting from step (f) in accordance with said instruction signals so that said deleted relatively low power signal portions are replaced by said signals of substantially constant amplitude; and (h) converting the signals resulting from step (g) to perceivable form.

A method of processing information bearing signals to initially reduce the information content thereof without destroying the intelligibility of the information contained therein and to synthesize signals from the processed signals, said method comprising the steps of: (a) Mozer phase adjusting said information bearing signals to produce equivalent signals having substantially symmetric portions; (b) deleting selected redundant portions of said equivalent signals; (c) X period zeroing said information bearing signals by deleting preselected relatively low power portions of the signals resulting from steps (a) and (b); (d) generating instruction signals specifying those portions of said signals deleted in steps (b) and (c); (e) reproducing the signals resulting from said steps of (a) Mozer phase adjusting, (b) deleting and (c) X period zeroing; (f) expanding said reproduced signals to supply said deleted redundant portions in accordance with said instruction signals; (g) inserting substantially constant amplitude signals between the non-deleted portions of the signals resulting from step (f) in accordance with said instruction signals so that said deleted relatively low power signal portions are replaced by said signals of substantially constant amplitude; and (h) converting the signals resulting from step (g) to perceivable form. 61. The method of claim 57 wherein said step of Mozer phase adjusting includes the step of transforming said information bearing signals to the frequency domain to produce a set of discrete amplitudes and phase angles, adjusting said phase angles so that the inverse transformation of the amplitudes and adjusted phases is at least partially symmetric, and inversely transforming said amplitudes and adjusting phases to the time domain; and wherein said step (b) of deleting includes the step of deleting fractional portions of those partially symmetric portions of said signals resulting from said step of inversely transforming.
