Audio enhancement communication techniques

This system improves audio quality in communication by detecting whether incoming signals are highly or weakly compressed, then applying specific enhancements tailored to that level. It can enhance signals in opposite directions between phones and selectively disable enhancement to prevent degrading sound quality. Claim 3 specifies that for some data, the enhancement process generates new data without directly using the decoded original data.

Why it matters: Filed before the widespread adoption of advanced machine learning for real-time audio processing. Today's AI models can adaptively enhance speech and reduce noise far more effectively across varying compression levels, making the adaptive enhancement described here much more powerful and practical.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
