Level formats
To make a ruler format the default (to be used in new Wave windows), you
need to save it as part of the default window style.
See “Styling WaveLab – Wave windows” on page 734.
Menu name Description
Time Positions are shown as hours, minutes, seconds and milliseconds. At large
magnification factors, hundredths of milliseconds are shown.
Samples Positions are shown as number of samples. How many samples there are to
a second depends on the sample rate of the wave. For 44.1 kHz for exam-
ple, there are 44100 samples for each second.
Time code Also called SMPTE. Positions are shown in the following format:
hours:minutes:seconds:frames.
The number of frames per second is set on the Preferences–Sync tab.
Meter Positions are shown as bars, beats and ticks, as specified on the Prefer-
ences–Sync tab.
File size Positions are shown in file size units, MegaBytes, where the decimals repre-
sent kiloBytes.
Menu name Description
% Amplitude (level) is shown as a percentage of full level.
dB Amplitude is shown in decibels, a logarithmic scale used in audio engineer-
ing.
Decimal This is the actual value of the amplitude as stored in computer memory (al-
ways displayed as 16 bits). Please note that the range is from negative to
positive with “0” representing “no signal”.
