Abstract
A wireless communication device reduces undesired audio underflow in a digital to analog receive path that employs time domain isolation. One or more buffers in the receive path receive processed audio samples from a signal processor. A control circuit senses when the buffers in the receive path are substantially empty. In response to a substantially empty determination by the control circuit, the control circuit instructs one of the buffers to repeat the last processed audio sample which that buffer received to reduce or avoid audio underflow.
