- The robustness of audio fingerprinting system in a noisy environment
is a principal challenge in the area of content-based audio retrieval,
especially for use in portable consumer devices. Our new audio
fingerprint method using sub-fingerprint masking based on the
predominant pitch extraction increases the accuracy of the audio
fingerprinting system in a noisy environment dramatically, while
requiring much less computing power compared to the expanded
hash table lookup method, where the searching complexity increases
by the factor of 33 times the degree of expansion.
