1. A device, comprising:
a processing system including a processor; and
a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising:
receiving an original audio signal for an interval;
creating a time-series graphical image of the original audio signal for the interval;
compressing the time-series graphical image, thereby creating a reduced resolution image;
recreating a retrieved audio signal from the reduced resolution image;
determining whether a comparison of the retrieved audio signal to the original audio signal meets a quality threshold;
responsive to meeting the quality threshold, compressing the reduced resolution image further and repeating the recreating and determining steps; and
transmitting a last reduced resolution image that meets the quality threshold.
