Abstract
A detector for determining an audio data bit rate of a pre-compressed audio elementary stream (AES), in which the pre-compressed AES includes a plurality of preamble length fields is provided. The detector includes an analyzer module configured to determine one or more candidate audio data bit rates of the AES from the plurality of preamble length fields, a detector module configured to determine whether one or more of the candidate audio data bit rates are correct, and a selector module configured to select one of the one or more candidate audio data bit rates determined to be correct as the audio data bit rate of the pre-compressed AES.
