ABSTRACT:
A method of using a waveform to sound pattern converter that produces an audible image of a time dependent signal by digitizing the signal to produce a plurality of discrete level signals, and produces a different audible tone signal for each level of the discrete level signals. A speaker is provided for producing audible sounds and circuitry is provided for driving the speaker to produce an audibly perceptible reference frame indicative of a predetermined time duration and also for driving the speaker with the audible tone signals such that the audible tone signals have the same time orientation with respect to each other as the discrete level signals have in the time dependent signal. The sounds are provided to listener to enable the listener to distinguish the shape of the time dependent signal based on the position and time relation of the tone signals relative to the reference time frame signal.
