analog audio
Refers to recording audio in a format of continuous vibrations that are analogous to the original sound waves. Before audio recording became digital, sounds were "carved" into vinyl records or written to tape as magnetic waveforms. Contrast with digital audio
AD is Analog to Digital conversion the use is to do digital measurements of analog voltages and currents, a computer soundcard is an AD converter that convert analog sound to digital sound so that it can be played on a computer, and DA is the opposite, digital to analog conversion, the digital sound on the computer is converted to analog sound to drive a speaker or headphone
When digital values are converted to create an analog sound, the term used is Digital-to-Analog converter.
No. Sound has to be converted from analog to digital for use by a computer, not the other way around. It is converted to analog so amplifiers and other analog equipment can use it and so you can hear it.

Sound itself is always analog, though the quality varies. Things on a a computer, iPod, TV, etc. are represented and transmitted digitally, but it is converted back to analog before it gets to the speakers. An example of analog sound storage would be a record player. While both are voltage, digital media is written in 1's or 0's, then converted back into a semi analog voltage to drive a speaker. To the trained ear, modern music which is stored digitally still doesn't sound as good as analog, due to loss in some of the frequencies we hear. Another way to create or transmit sound is acoustic, which is that of a nonelectric guitar or saxophone.
There are many different noted differences of an analog sound system when compared to a digital sound system. The most referenced difference is that of quality of sound.
Naturally occurring sound waves are analog, although they can be digitized.
The big difference is inputs and outputs. Digital ICs expect high/low true/false inputs and outputs. Analog ICs take any inputs, and produce outputs of any level. For example, an audio amplifier is an analog IC. It takes an analog input (sound), and produces an analog output (louder sound). A ripple counter is an example of a digital IC. It takes a digital input (clock pulses), and produces a number of digital outputs (the digital outputs of the flip flops, collectively representing a number in binary).
The examples of analog devices are as following: 1. The telautograph 2. Analog synthesizer 3. Analog television 4. Analog Computer
Well analog is usually used to carry sound so amplifying the analog signal would make it louder.
That would be analog. A speaker is not just on or off, and its range varies as the voltage changes. Sound cards use a D/A converter to convert digital data to audible sound.
As compared to digital audio which consists of a stream of 1's and 0's, analog audio is transmitted via a physical quantity, such as a voltage. Analog recordings are physically stored, for example in a vinyl record, the record face consists of small pits and valleys that are then converted into sound. Fluctuations in electrical or magnetic fields is another method of storing analog audio.
