Abstract: A system, such as an ear-wearable device or a hearing aid, can receive multiple audio signals representing a same audio content, can cross-correlate the multiple audio signals to determine relative delays between the audio signals, can apply the determined delays to at least one of the audio signals to form multiple synchronized audio signals, and can mix at least two of the synchronized audio signals in time-varying proportions to form an output audio signal. The system can optionally adjust the mix proportions, in real time, to increase or optimize the signal-to-noise ratio of the output audio signal. The system can optionally perform the cross-correlation repeatedly, at regular or irregular time intervals, to update the relative delays. The system can optionally divide the audio signals into frequency bands, and apply these operations to each frequency band, independent of the other frequency bands.

An example welding-type power supply includes an interface device to receive a commutation selection input, a power converter to convert input power to welding-type power, a commutator circuit to output alternating current (AC) welding-type power and to control a polarity of the AC welding-type power, and a control circuit. The control circuit determines a threshold output current based on the commutation selection input, determines an output current and a polarity of the AC welding-type power and, when the output current is less than the threshold output current, controls the commutator circuit to change the polarity of the AC welding-type power.
