Abstract:
Frequencies from a set of audio source files are extracted and measured across the set to determine a range of each of the frequencies. Stable frequencies of the frequencies are detected based on each range and used to create a stable frequency family. An unknown recording is mapped to the stable frequency family to form an audio fingerprint.
