Abstract: Methods and apparatus for detecting audio anomalies from a reference audio file and a sampled audio filed. In embodiments, a system can perform aligning in time first and second audio files, dividing the first and second audio files into chunks, performing time-based processing of the amplitude adjusted output of the first and second audio files to identify audio anomalies in the second audio file, and performing frequency-based processing of the amplitude adjusted output of the first and second audio files to identify audio anomalies in the second audio file.

Abstract: The frequency of a clock signal is compared to a predetermined range. If the measured frequency is outside the range, a system controller determines if a current operating state of the overall system allows for the internal clock to be adjusted back into compliance. If the controller determines that the current system state allows for the change, then a control signal to the internal clock signal source is changed by the smallest increment available, either to increase or decrease the frequency. If the internal clock signal is out of the desired range, and the system controller does not decide to modify the frequency, the controller may increase the size of the range by decreasing the lower bound and/or increasing the upper bound.
