13.28 ECMAScript 183
13.28 ECMAScript
WaveLab's scripting language is based on the ECMAScriptscripting language, as defined
in "Standard ECMA-262 - ECMAScript Language Specification".
Microsoft's JScript, Netscape's JavaScript and Adobe's Actionscript are also based on the
freely-available ECMAScript standard.

13.34 FTP Site
File Transfer Protocol (FTP) is a network protocol used to copy a file from one host to another
over a TCP/IP-based network such as the Internet. An FTP sitemay require user-based
password authentication or it may allow anonymous user access. Podcasts are published to
FTP sites.

13.39 Loudness
Loudness is a subjective measure, the perceptual correlate of amplitude of sound. There
are objective measures of sound strength, such as SPL (sound pressure level in dB), but
Loudness is affected by other factors, principally frequency (the sensitivity of the human ear
changes as a function of frequency) and duration.
The perception of...

MIDI provides 16 channels for sending data. When processing MIDI triggers, WaveLab
Elements needs to know which MIDI channelto monitor to receive a trigger.

standard, and derived from MP2. MP3 is popular for PC and internet applications - data
compression ratios of 10:1 are typical.
Note that when you open an MPEG compressed file in WaveLab, the file is converted to a
temporary wave file that is much larger than the original compressed file, so make sure that
you have enough free space on your hard disk when opening MPEG compressed files. On
saving, the temporary wave file is converted back to MP3, so from a user perspective the...

13.51 Ogg Vorbis files
Ogg Vorbis is a lossy compressed audio format and codec that produces files about the
same size as MP3 files but with objectively higher fidelity and no patent restrictions.
Vorbis is intended for sample rates from 8kHz telephony to 192kHz digital masters and a
range of channel representations that includes monaural, stereo, surround 5.1, ambisonic,
or up to 255 discrete channels. Vorbis is open source (free) software maintained by the
Xiph.Org Foundation.
The file...

13.55 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...

13.59 Processor cores
Processor cores Modern computers are often designed with a multi-core processor, with
two or more "cores" (i.e. independent processors) in a single physical package. A dual-core
processor contains two cores, and a quad-core processor contains four cores, with the aim
of improving computational performance.
The performance gains of multi-core processors depend on whether the software has been
implemented to take advantage of this architecture.

sectors of 2352 bytes ("frames"), read at 75 frames/s. The bit rate is 1411.2kbits/s. Other
considerations are that the maximum number of tracks is 99, the minimum duration of a track
is 4 seconds (including a 2-second pause), the maximum playing time is 79.8 minutes, and
the ISRC should be included.
WaveLab Elements provides Red Book-compliant CD mastering.

192 Glossary
RMS is often a good basis for determining an "equal level" when equalizing Clip volumes,
producing more natural results than using Peak levels, since RMS offers a more realistic
measure of the perceived "loudness" of a sound.

13.66 Sample rate
The Sample Rate , or sampling frequency, is the number of samples per second used to
store a sound. High sample rates are better able to approximate the original continuous
waveform, but require more storage space....
