SOUND FORGE

Bit Depth
The number of bits used to represent a single sample. For example, 8-or 16-bit are common sample sizes.
While 8-bit samples take up less memory (and hard disk space), they are inherently noisier than 16-or 24-bit
samples.

Amplitude Modulation
Amplitude Modulation (AM) is a process where by the amplitude (loudness) of a sound is varied over time. When varied
slowly, a tremolo effect occurs. If the frequency of modulation is high, many side frequencies are created that
can strongly alter the timbre of a sound.

Adaptive Delta Pulse Code Modulation (ADPCM)
A method of compressing audio data. Althugh the theory for compression using ADPCM is standard,
there are many different algorithms employed. For example, Microsoft's ADPCM algorithm is not compatible
with the International Multimedia Association's (IMA) approved ADPCM.

Loop
Loops are small audio clips that are designed to create a repeating beat or pattern. Loops are usually
one to four measures long.
