Abstract

In this paper an approach for algorithm selection for automated audio classification is proposed based on content. Three popular algorithms for speech vs. music discrimination are incorporated, namely the zero-crossing rate, average frame power and 4-Hz energy modulation which prove effective at different level depending on the content of the audio being processed. Extensive testing is done over various musical pieces from different countries and in different styles to evaluate the accuracy and time consumption for each one. Then based on registered levels and with statistics from the initial record for particular audio recording the most proper could be switched on for processing in a complete audio classification system. Obtained results re considered promising for future use on a wider scale.
