Methods and systems for active noise control in an audio playback device

A system for active noise control (ANC) in an audio playback device, the system comprising:

• a memory;
• at least one processor, comprising processing circuitry, communicatively coupled to the memory, wherein at least one processor, individually and/or collectively, is configured to cause the system to:
• receive, via a first audio input device, comprising a microphone, positioned outwardly on the audio playback device, an ambient audio signal;
• receive, via a second audio input device comprising a microphone positioned inwardly on the audio playback device, a feedback audio signal;
• determine an estimated leaked signal based on the ambient audio signal and the feedback audio signal;
• extract, from the ambient audio signal, an initial anti-noise audio signal corresponding to dominant noise sources within a plurality of sub-bands of the ambient audio signal;
• estimate one or more ear canal parameters associated with a user of the audio playback device based on the feedback audio signal, the estimated leaked signal, and the initial anti-noise audio signal;
• and
• generate an anti-noise signal for playback via the audio playback device based on the one or more ear canal parameters to achieve the ANC at the audio playback device.
