Abstract:
1. An audio streaming playback system comprising: speech processor means for sensing and processing audio sound signals along an audio signal processing path of said speech processor means, said speech processor means including a multiplicity of tap points along said audio signal processing path at which the audio sound signals may be accessed; and an audio streaming circuit for accessing the audio sound signals at the multiplicity of tap points along the audio signal processing path of the speech processor means, wherein the audio streaming circuit includes an auto-referencing mixed-mode phase locked loop circuit that includes (a) means for receiving digital audio samples at a consistent, but unknown, average rate, (b) means for extracting the average sample rate, (c) means for generating a local clock signal at the average sample rate, and (d) means for re-synchronizing the digital audio samples to the local clock signal when audio playback is desired.
