Abstract
A method includes receiving samples of audio data and storing the samples of audio data in a buffer. Each of the samples of audio data includes a plurality of bits. The method also includes transmitting each of the plurality of bits, of each of the samples of audio data retrieved from the buffer, across a single-bit bus; and subsequent to transmitting each of the samples, transmitting a selected number of dummy bits across the single-bit bus. The selected number is greater than one. The method further includes analyzing activity of the buffer and, based on the activity of the buffer, dynamically adjusting the selected number. The method also includes acquiring the samples of audio data transmitted across the single-bit bus and ignoring the dummy bits. The method further includes generating analog signals in response to the samples of audio data acquired across the single-bit bus.
