Audio processing pipeline for auditory prosthesis having a common, and two or more stimulator-specific, frequency-analysis stages

摘要

An audio processing pipeline, for an auditory prosthesis, includes: a common stage, including a common frequency analysis filter bank, configured to generate a common set of processed signals based on an input audio signal; and first and second stimulator-specific stages, responsive to the common set of signals and including first and second frequency-analysis filter banks, configured to generate first and second sets of processed signals adapted for the first and second hearing stimulators, respectively.

1. An audio processing pipeline for an auditory prosthesis, the pipeline comprising:
a common stage, including a common frequency analysis filter bank, configured to generate a common set of processed signals based on an input audio signal; and first and second stimulator-specific stages, responsive to the common set of signals and including first and second frequency-analysis filter banks, configured to generate first and second sets of processed signals adapted for the first and second hearing stimulators, respectively, wherein the common stage further includes: a frequency-domain transformer configured to transform the input audio signal from the time-domain into the frequency-domain and provide the transformed audio signal to the common, frequency-analysis filter bank.
