Abstract: Example implementations relate to audio samples to detect device anomalies. For example, computing device, comprising: a processing resource and a non-transitory computer readable medium storing instructions executable by the processing resource to: generate a matrix of audio information for a plurality of audio samples of a device, select audio information from one of the plurality of audio samples, generate a plurality of principal components for the selected audio information utilizing a principal component expansion, select a principal component from the plurality of principal components based on a quantity of variance, and detect an anomaly of the device based on a comparison between a real time audio sample of the device and the selected principal component.

Abstract: An example method comprises identifying a plurality of zones of a spectrogram of an audio sample associated with an operation cycle of an imaging device, generating a set of audio models by transforming the audio sample to a power spectrum and identifying a plurality of audio features within the power spectrum and for the plurality of zones, generating a plurality of simulated audio samples using the set of audio models by adjusting an audio feature of the plurality of audio features, and outputting a set of training data including the audio sample and the plurality of simulated audio samples to train a predictive model indicative of a predicted failure of the imaging device.
