Real-time binaural audio detection and enhancement

A method for adaptive real-time stereo amplitude-domain audio enhancement, the method comprising:

• receiving, at a digital signal processor, left- and right-channel digital audio signals;
• detecting instantaneous amplitude peaks within each channel to identify narrowband spectral components exceeding amplitude thresholds;
• separating each channel into a plurality of frequency bands including at least five per channel;
• monitoring amplitude within each band and comparing the amplitude to a dynamic threshold that varies with instantaneous input level;
• when the threshold is exceeded, applying micro-amplitude modulation within that band in real time at a modulation rate of about 1 Hz or faster, with zero or effectively zero latency;
• introducing a controllable interaural amplitude offset between the left and right channels corresponding to a selected modulation-frequency range of approximately 1 Hz to 100 Hz;
• introducing controlled resonant feedback within one or more bands so that equalization continuously evolves in response to interaction with the live audio signal;
• and
• outputting the same stereo audio signal enhanced only through amplitude-domain modulation of existing frequency components, without mixing, summing to mono, resynthesizing, or generating new content.

• storing instructions executable by a processor for real-time stereo adaptive amplitude modulation, the instructions, when executed, performing a method comprising:
• receiving left- and right-channel digital audio signals;
• detecting a plurality of narrowband spectral components exceeding adaptive thresholds;
• applying adaptive amplitude modulation to at least one detected component in real time without performing resynthesis or oscillator generation;
• and outputting a stereo signal corresponding to the received audio and including the adaptively modulated amplitude pattern.
