| 1. An apparatus for forming an audio template for determining semantic audio information, the apparatus comprising:
a processor to:
extract a plurality of audio features from audio, at least one of the plurality of audio features including at least one of
a temporal feature, a spectral feature, a harmonic feature, or a rhythmic feature;
determine a range for each of the plurality of audio features; and
store a set of ranges of the plurality of audio features to compare against other audio features from subsequent audio to
generate a tag for the set of ranges signifying semantic audio information for the subsequent audio, wherein the set of ranges
includes more than one range and the tag is associated with an audio timbre range, a beat range, a loudness range and a spectral
histogram range.
