There is no standardized canonical fingerprint and never will be, because the audio features covered by the fingerprint vary with the use case. For example a fingerprint might or might not need to draw these distinctions: - Clean ("Walmart") and dirty (profanity) mixes of the same recording - Amount of opening and closing silence (often varies across releases) - Different masterings - Fidelity of the source recording (e.g. 64K Real Audio vs uncompressed PCM) In addition, fingerprint developers are constantly improving on their algorithms.
