Sound
Audio file formats.
-
AAC is a cross-platform format that has become widely popular from its use on phones, pad computers, digital radio, and video game consoles
-
CD-ROM/XA (Extended Architecture) format enabled several recording sessions to be placed on a single CDR (recordable) disc
In Windows, digitized sounds are usually stored as WAV files
-
On the Macintosh, digitized sounds may be stored as data files, resources, or applications such as AIFF or AIFC
WAV, AIFF, AU, RAW, and PCM files can store uncompressed audio data
-
MP3, AAC, and WMA files are compressed audio data
Digital audio.
Digital audio data is the actual representation of sound,
stored in the form of samples.

Monophonic
Commonly called mono sound, mono or non-stereo sound, this early sound system used a single channel of audio for sound output.
-
Mono (monophonic, or monaural) is sound from a single source.
-
Stereophonic
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.
Stereo (stereophonic) is sound from two sources,ideally spaced apart,and reproduces sound the way
we hear it naturally,with two ears.

-
standard protocol for the interchange of musical information between musical instruments, synthesizers, keyboard controllers, sound cards, computers and all other electronic instruments from all manufacturers
MIDI file is very small, often as small as 10 KB for a 1-minute playback (it doesn’t contain audio waves)

-
The speed at which most animations and computerbased videos play, depends on the user’s CPU
-
-
-
Copyrighted material should not be recorded or used without securing appropriate rights from owner or publisher
Recording on inexpensive media rather than directly to disk prevents the hard disk from being overloaded with unnecessary data
Professional sound.
The amount of digital sound information required for highquality sound takes up a great deal of disk storage space

-
File size of digital recording (in bytes) = sampling rate X duration of recording (in secs) X (bit resolution/8) X number of tracks.

events such as startup and warnings, among others.

Multimedia sound is either digitally recorded audio or MIDI (Musical Instrumental Digital Interface)music.
