Tandy 8-bit DAC hardware is a type of Covox Speech Thing clone but resided in internal hardware rather than occupying the parallel port and the necessary CPU bandwidth need to converse with that port. It benefited from DMA allowing sound and music to be processed without taking up CPU cycles. It is capable of playback and synthesizing of 48kHz sound and music. It was used to emulate other sound hardware such as the Speech Thing and certain functions of Sound Blaster cards. Or, games could simple use all six channels at once as the DAC was integrated with the previous "Tandy 3 Voice" hardware.
