6.5.3 Resolution
The frequency resolution on all SPECTRO LAB views (SDC, RTS, and AVG) is based on a constant-Q analysis. This makes it easier to see details in the whole frequency
spectrum as compared to many other real time analyzers which have too little information in the bass range and too much information in the treble range (‘grass’).
A constant-Q representation is also much closer to the “frequency analysis” known from psychoacoustics to be performed by the cochlea in the inner ear.
Note that all of the spectral views take the track length into account, so a double-length track, for example, is not shown with an approximately 3 dB higher level.
6.5.4 SDC display using a Sinewave Source
The examples below show the SPECTRO LAB views for some simple input signals such as a constant sine wave or pure tone. Further examples are shown using pink
noise and brown noise sources, clearly showing the spectral dynamic contour (SDC) curves.
Because the pure tone, in this example, is constant throughout the track, all the level contours of the SDC collapse into the same curve. The shape of the tone in the
SDC corresponds to the 1/6th octave frequency resolution employed by the SDC analysis.
