8. The system of claim 7 , wherein the spectral peak data associated with the first query and the spectral peak data associated with the at least one additional query comprise a time index and a frequency location corresponding to the spectral peak data.
8. The system of claim 7 , wherein the spectral peak data associated with the first query and the spectral peak data associated with the at least one additional query comprise a time index and a frequency location corresponding to the spectral peak data. 17. The system of claim 8 , wherein said scanning the content database across the first beam width comprises: producing one or more time positions at the frequency location corresponding to an extracted spectral peak; and assigning a content score to a content item corresponding to each of the one or more time positions, the content score corresponding to a difference between the one or more time positions of the content item and the time index of the extracted spectral peak of the query, the content item corresponding to one of the one or more candidates; and wherein the scanning the one or more candidates is based on the content score.
