Relatively high sound quality is produced from a standard computer speaker without using a digital to analog converter. Error propagation techniques are used to position the cone of a speaker at a position proportional to a waveform sample. Hysteresis may be employed to retard the frequency of the positional changes of the speaker cone to increase the volume of the speaker. An interpolative technique may be employed to produce a smoother transition between waveform samples.
