WAVELAB
25 – 628 Analysis
Usage guidelines
The result is an average value for the whole selection.
The method only works on monophonic material (not on chords or harmonies).
The algorithm assumes the analysed section has a reasonably stable pitch.
The material must be relatively well isolated from other sounds.
It is preferable to analyse the sustain portion of a sound, rather than the attack.
The pitch is usually not “stable” during the attack.
Some synthetic sounds may have a weak fundamental (first harmonic) which can
fool the algorithm.
The Extra tab
This tab shows you two things:
The average DC Offset in the analysed section.
See “Eliminate DC Offset” on page 195 for details.
The Apparent Bit Resolution.
This attempts to detect the actual resolution in the audio, i.e. how many bits are really used.
This is useful e.g. if you want to check whether a 16 bit file really uses 16 bits (or if it was
actually recorded with only 8 bit resolution and then expanded up to 16 bits).
You may want to use the Bit Meter for this instead (preferably in “Analyse Se-
lection” mode), as this is even more accurate (see “Bit Meter on page 170.
