Abstract
Systems and methods for converting a data stream from a first sample rate to a second sample rate, where the data is received in bursts. In one embodiment, a method includes receiving bursty audio data on a first input line and receiving synchronization data on a second input line that is separate from the first input line. An input sample rate is then estimated for the received audio data based on the received synchronization data and the audio data is converted to an output sample rate. The input sample rate is determined by counting samples received in a time interval and potentially low-pass filtering the result. The audio data may be in packetized, parallel, or other forms, and the synchronization data may include individual signals, such as pulses or bits received at regular or irregular intervals.
