Patent ID: 7603270

Claim:
Method of transmitting audio signals between a transmitter and at least one receiver, comprising the steps of: (a) resolving an audio signal into a number n of spectral components through a number n of frequency selective filters; (b) storing the resolved audio signals in a two-dimensional array having a multiplicity of fields, and wherein frequency and time are stored as dimensions of the array and the amplitude as a particular value to be entered in a field within the multiplicity of fields of the array; (c) combining each field of the multiplicity of fields into a field group wherein there are a plurality of field groups formed from the multiplicity of fields, and each field group is formed from at least three adjacent fields; (d) assigning a priority to each group of the plurality of field groups, the priority of one group over another group becoming greater based upon at least the function of the greater the amplitude differences of the values of a group (e) sorting the field groups of said array with the aid of their priority value; (f) storing and/or transmitting the groups to the at least one receiver in the sequence of their priority; and (g) transmitting said audio signals at low transmission bandwidths so as to minimize transmission losses.
