I performed a quick analysis of Billie Jean, which stems from the Thriller CD. The drums offer peaks ranging from 466 – 400 Hz whereas the bass rhythm section is 122 – 110 Hz. Those two frequencies are the dominant peaks in the track. The above was evaluated using Elemental Audio IXL Spectrum Analyser.
SPL offers a continuous average level ranging around –17.5 dB (peaks -14.5 dB) and, peaks @ 0 dB using the Sonoris Demonstration Meter. Bear in mind, within the first bars of the track before the rhythm section begins, the Sonoris meter states the signal clipped 1 time on the left channel and, 6 times on the right.
The Off The Wall track I have kept clipping excessively on peaks, and offer a continuous average of –8.6 dB on the left and, -8.4 dB on the right channel. The figures reflect the first 30 seconds of the track and get worse as you approach the end of the track.
The picture below reflects the readout on the Sonoris Meter to wards the end of the track entitled “Off The Wall.”
Cheers!
