Abstract:
1. A method comprising: receiving a first audio signal; receiving a reference clock associated with a signal other than the first audio signal; determining a specified number of frames; determining a specified number of clocks per number of frames; generating an audio pulse for each specified number of frames in the first audio signal; counting clock pulses in the reference clock for each audio pulse; generating one or more count signals associated with the counted clock pulses; averaging the one or more count signals; generating a signal that identifies an input number of clocks per number of frames based on the average; obtaining an audio sample signal from an audio sample buffer, wherein the audio sample signal is associated with the first audio signal; generating a ratio signal based on the input number of clocks per number of frames and the specified number of clocks per number of frames; and re-sampling the audio sample signal based on the ratio signal, the specified number of frames and the specified number of clocks per number of frames.
