1. A method for forming an audio template for determining semantic audio information, comprising the steps of:

  • receiving a plurality of audio signals in a computer processing device;

    extracting a first audio feature from each of the received audio signals, said first audio feature comprising at least one of a temporal, spectral, harmonic and rhythmic feature;

    extracting a second audio feature from each of the received audio signals, said second feature comprising at least one of a temporal, spectral, harmonic and rhythmic feature, wherein said second audio feature is different from the first audio feature;

    determining a first range for the first audio features and a second range for the second audio feature;

    associating and storing the first and second ranges for comparison against other audio features from subsequent audio signals to generate tags signifying semantic audio information for the subsequent audio signals.
