Abstract

Methods, apparatus, and articles of manufacture for media monitoring are disclosed. In particular, the example methods, apparatus, and articles of manufacture generate digital spectral signatures for use in identifying media information. Initially, a frame of media samples is obtained. A first frequency component having a first spectral power and a second frequency component having a second spectral power are identified by performing a spectral transform operation on the frame of media samples. A descriptor of the first frame of media samples is determined based on a comparison of the first spectral power and the second spectral power. A first signature is then generated based on the descriptor.
