Abstract
Official abstract text for this publication.
Disclosed is a frame comparison apparatus and method for comparing frames included in an audio signal by using spectrum information. The frame comparison apparatus includes a spectrum information estimation apparatus for receiving an audio signal and estimating and outputting spectrum information for the respective frames included in the audio signal, an estimation operation option determiner for determining an estimation order of the spectrum information estimated from the spectrum information estimation apparatus, a frame comparison option determiner for determining a comparison order for the frames output from the spectrum information estimation apparatus, and a frame comparator for determining a comparison target frame which is a comparison target for a current frame included in the audio signal, comparing the spectrum information for the current frame with the spectrum information for the comparison target frame, and outputting a comparison result value.
First claim
Opening claim text (preview).
What is claimed is: 1. A frame comparison apparatus for comparing frames included in an audio signal, the frame comparison apparatus comprising: a spectrum information estimation apparatus to estimate spectrum information in at least one frames included in the audio signal; an estimation operation option determiner to determine an order of a peaks spectrum in the spectrum information output by the spectrum information estimation apparatus; a frame comparison option determiner…
