10. A system for performing sound filtering selection, comprising:
a training track feature classifier operable to, for each training audio track of a plurality of training audio tracks, generate a training audio track feature vector including a plurality of training track vector components based on one or more feature sets;
a cluster generator operable to group each of the plurality of training track vector components of the training audio track feature vector into at least one of a plurality of clusters;
a mapper operable to map a first set of audio filters to one or more of the plurality of clusters, thereby building a feature-to-filter mapping function from each training audio track feature vector to at least one audio filter;
a mapping function store operable to store the feature-to-filter mapping function; and
an audio filter server operable to provision the feature-to-filter mapping function to a media playback device enabled to apply the feature-to-filter mapping function to a query audio track.
