Commonly called stereo sound or sterophonic sound, stereophonic sound divides sounds across two channels (recorded on two separate sources) then the recorded sounds are mixed so that some elements are channeled to the left and others to the right. Stereophonic sound is generally considered the best sound technology of the 1950 and early 1960's.
Channel
A band of frequencies used in radio and television transmission, esp. as used by a particular station.
Track
A section of a record, compact disc, or cassette tape containing one song or piece of music.
Frequency
The rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light), usually measured per second.
Hertz
The SI unit of frequency, equal to one cycle per second
Decibel
A unit used to measure the intensity of a sound or the power level of an electrical signal by comparing it.
Wav, mp3, aiff
Wav- An audio file format. Very accurate, but offers no compression, thus resulting in very large files.mp3- A computer file format that compresses audio files up to a factor of 12 from a .wav file.
aiff- Apple’s native uncompressed audio file format created for the Macintosh computer, commonly used for the storage and transmission of digitally sampled sound.
