When a sine wave is mixed with one of identical frequency but opposite amplitude (ie: of an inverse polarity), the combined result is silence. [2] A two-channel stereo recording contains a number of waveforms; sounds that are panned to the extreme left or right will contain the greatest difference in amplitude between the two channels, while those towards the centre will contain the smallest.

Linear pulse-code modulation (LPCM, generally only described as PCM) is the format for uncompressed audio in media files and it is also the standard for CD-DA; note that in computers, LPCM is usually stored in container formats such as WAV, AIFF, or AU, or as raw audio format, although not technically necessary.
Sound-on-film is a class of sound film processes where the sound accompanying a picture is recorded on photographic film, usually, but not always, the same strip of film carrying the picture. Sound-on-film processes can either record an analog sound track or digital sound track, and may record the signal either optically or magnetically .
When it is necessary to capture audio covering the entire 20–20,000 Hz range of human hearing [6] such as when recording music or many types of acoustic events, audio waveforms are typically sampled at 44.1 kHz , 48 kHz, 88.2 kHz, or 96 kHz. [7] The approximately double-rate requirement is a consequence of the Nyquist theorem. Sampling rates ...
For sound effects, the OPL4 can be connected to the Yamaha YSS225 effects processor (EP), which adds various sound effects. Like its predecessors, the OPL4 outputs audio in digital-I/O form, thus requiring an external DAC chip. The YMF278 is used with the Yamaha YAC513 DAC chip, which was also used with the YMF262 prior.
The various serial digital interface standards all use (one or more) coaxial cables with BNC connectors, with a nominal impedance of 75 ohms. This is the same type of cable used in analog composite video setups, which potentially makes for easier "drop in" equipment upgrades (though may be necessary for long runs at the higher bitrates for older oxidising or lower grade of cable to replaced ...
