The present invention provides methods, computer-readable media, and apparatuses for determining a measure a similarity of the audio content of a plurality of files. Quantized samples are converted to energy values from files having audio content with compressed formats. Energy characteristics are determined from the energy values and are matched to obtain a greatest content match for a plurality of delay instances. A selected delay value corresponds to a determined offset between the files for relating the audio content of the files. A degree of similarity is determined to relate the audio content of the files. A frequency spectrum is partitioned into a plurality of frequency bands, and a total energy value is determined for each frequency band. The total energy values are correlated for the files.
