On the face of it, who would expect the difference between an 80 In fact, it seems counter-intuitive: As you reduce the playback loudness on your AV receiver, the negative numbers grow larger, and when you exceed the 0 dB mark as you crank up your AV receivers volume to extremely loud levels and possible distortion, the positive numbers are tiny: +3 dB, +6 dB, and so on. The use of the VU meter in broadcasting and recording was to ensure a strong enough audio signal that was well above any noise, yet prevent a too-loud signal that might distort or overload any recording equipment or the input circuits of the control consoles in the other radio stations.

"Calling DB->open is a relatively expensive operation, and maintaining a set of open databases will normally be preferable to repeatedly opening and closing the database for each new query." On of the reasons for which opening a database is expensive, is that it requires I/O from disk, to uniquely identify the file. With music, are you able to detect a 1-dB increase or decrease in loudness?
