ABSTRACT:
Audio streaming is made available throughout the signal processing path of a speech (or audio) processor of a cochlear implant system. Audio streaming allows one to “listen in” to what a cochlear implant patient may be hearing. As an audio signal stream is received and digitally processed, it may be sampled at any of a number of sample points. The signal at a selected sample point allows appropriate diagnostics to be performed. An auto-referencing mixed-mode phase locked loop processes an asynchronous stream of digital audio samples that arrive at a consistent, but unknown, average rate. Once received, the average sample rate is extracted, and a local clock is generated at the average frequency. The incoming audio streaming samples are then re-synchronized with the local clock in order to allow digitally phase locked playback of the audio stream.
