Abstract: Adaptive filtering is described for use with amplifiers for any wired speaker. In one example, an apparatus includes an audio cable to provide an analog audio signal to an audio transducer, such as a speaker, the audio cable also receiving a modulated noise current, an output amplifier to receive an audio input, to generate an audio output by amplifying the audio input, and to provide the audio input to the audio cable, and a feedback system to receive the audio output and to receive a reference signal and to generate a noise cancellation signal to the output amplifier, the noise cancellation signal to cancel the modulated noise current.
