A music information searching method includes extracting modulating spectrums from audio data, generating modulating spectrum peak point audio fingerprints by using position information which relates to preset peak points from the extracted modulating spectrums, converting the generated modulating spectrum peak point audio fingerprints into hash keys which indicate addresses of hash tables and hash values that are stored on the hash tables via hash functions, and searching music information by extracting hash keys which relate to audio query clips and comparing the extracted hash keys with the indicated addresses of the hash tables.

Music information searching method and apparatus thereof

A signal processing apparatus which processes a voice packet is provided. The signal processing apparatus includes: a network jitter measurer which estimates network jitter using a weighting of a network jitter variance according to a network state, a compression and output unit which compresses or outputs a voice frame based on the estimated network jitter, and a loss concealer which divides a voice packet loss into short-term loss concealment and long-term loss concealment, and performs loss concealment in a different way depending on whether the voice packet loss is the short-term loss concealment or the long-term loss concealment.
