Compression Ratio 
(file size)The ratio of the size of the original noncompressed file to the compressed 
contents. For example, a 3:1 compression ratio means that the compressed file is 
one-third the size of the original.
Computer IDEach computer has a unique number, similar to a license plate. Sonic Foundry 
creates an activation number for ACID based on that number. Since the 
activation number is based on the Computer ID, it is important that you have 
ACID installed on the...

Drag and DropA quick way to perform certain operations using the mouse. To drag and drop, 
you click and hold an item, drag it (hold the left mouse button down and move 
the mouse) and drop it (let go of the mouse button) at another position on the 
screen.
Dynamic RangeThe difference between the maximum and minimum signal levels. It can refer to 
a musical performance (high-volume vs. low-volume signals) or to electrical 
equipment (peak level before distortion vs. noise floor)....

MIDI PortA MIDI port is the physical MIDI connection on a piece of MIDI hardware. This 
port can be a MIDI in, out or through. Your computer must have a MIDI-capable 
card to output MIDI timecode to an external device or to receive MIDI timecode 
from an external device.
MIDI Timecode 
(MTC)MTC is an addendum to the MIDI 1.0 specification and provides a way to specify 
absolute time for synchronizing MIDI-capable applications. MTC is essentially a 
MIDI representation of SMPTE...

Pulse Code 
Modulation (PCM)PCM is the most common representation of uncompressed audio signals. This 
method of coding yields the highest fidelity possible when using digital storage. 
PCM is the standard format for WAV and AIFF files.
QuantizationThe correction of rhythms to align with selected note lengths or beats in a MIDI 
sequence.
Real-Time

Shortcut MenuA context-sensitive menu that appears when you right-click certain areas of the 
screen. The functions available in the shortcut menu depend on the object being 
right-clicked as well as the state of the program. As with any menu, you can 
choose an item from the shortcut menu to perform an operation. Shortcut menus 
are used frequently in ACID for quick access to many commands.
Signal-to-Noise 
RatioThe signal-to-noise ratio (SNR) is a measurement of the difference...

GLOSSARYAPPENDIX C
WAVA digital audio file format developed by Microsoft and IBM. One minute of 
uncompressed audio requires 10 MB of storage.
WaveformA waveform is the visual representation of wave-like phenomena, such as sound 
or light. For example, when the amplitude of sound pressure is graphed over time, 
pressure variations usually form a smooth waveform.
Waveform DisplayEach event shows a graph of the sound data waveform. The vertical axis 
corresponds to the amplitude of the wave. For 16-bit...
