1. A method to identify media, comprising: generating, using a processor, a reference signature based on a reference signal corresponding to known media; generating, using the processor, sums based on peaks in a media signal corresponding to media; identifying, using the processor, signal peaks based on the generated sums; generating, using the processor, a second signature based on normalized curve features, wherein the normalized curve features respectively correspond to the identified signal peaks at a corresponding temporal locations of the corresponding signal peak; and determining, using the processor, whether the media signal corresponds to the reference signal based on a comparison of the reference signature and the second signature.
