15.54 Pan 407
in broadcast television systems in large parts of the world. NTSC is a another analog system
used in North America and parts of South America.
In digital applications PAL video mode is usually referred to as "576i" (i.e. a vertical resolution
of 576 scan lines, interlaced), in analogue contexts it is often quoted as "625 lines". SECAM
Digital video uses its own colour space, so (in the digital domain) the minor colour space
differences that used to exist between PAL and SECAM are no longer present.
In digital video applications such as DVDs and digital broadcasting, PAL/SECAM video is
based on 576 frame lines with two interlaced video fields per frame (i.e. 50 fields per second,
yielding 25 frames per second). Audio is pulse-code modulated.

15.54 Pan
Pan is short for panoramic. Pan is perceptually "placing" a mono or stereo sound source
between two or more speakers. We sense stereo position from a difference in loudness
when the sound strikes each ear, taking into account the time delay, spectrum, reverberation
and other cues.

15.55 Peak level
Peak level is a measure of maximum sound level. Peak Level Meters should go as high as
possible without ever reaching 0dB! The Peak Level meters display the peak levels of each
channel, graphically and numerically.
By default, the meter segments and numerical peak values are displayed in green for low
levels, yellow for levels between –6dB and –2dB, and red for levels above –2dB.
If the level is set too low, noise levels will be high relative to the recorded sound; if peak level
exceeds 0dB by a significant amount, clipping effects can occur.

15.56 Plug-ins
A vast number of specialist audio software Plug-ins are available, ranging from freeware to
expensive high-end commercial products, and these can greatly extend the functionality of
WaveLab.
Steinberg created Virtual Studio Technology (VST) to allow effect plug-ins to be integrated
with audio editors (such as WaveLab). VST uses Digital Signal Processing (DSP) to emulate
in software the effects of familiar recording studio hardware.
