1. A method to credit media, comprising:

  • comparing, with a processor, a first crest factor stored in a memory in association with a media identifier to a second crest factor corresponding to a ratio of a peak amplitude of an audio signal and a root mean square value of the audio signal;

    determining, with the processor, that spillover did not occur if a difference between the first crest factor and the second crest factor satisfies a threshold; and

    when the spillover did not occur, crediting, with the processor, a media exposure to media associated with the audio signal.
