1. A computing device, comprising:
a processing resource;
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 analysis (PCA);
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.
