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.

What is the definition of sound device?
Sound devices are devices for analog and digital audio products for radio, television, film, and music recording.
What are the two basic kinds of electronic signals?
Analog and digital :)
What are the 3 types of sounds?
There are 3 main classifications of sound. These sounds can be classified by volume, by source, and also by intent.
What are the kinds of electrons?
Electronics divides in analogue and digital one. Electronics is a physical branch of electron emission and behavior. Analog and digital are not two kind of electronics.
What is a heat sensor?
it is a device that turns a measure of heat into an electrical signal it can be digital (on-off) like a switch or it can be analog (0% to 100%) like a mechanical themometer
What are AD and DA?
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
What is the term used when digital values are converted to create an analog sound?
When digital values are converted to create an analog sound, the term used is Digital-to-Analog converter.
Does sound have to be converted from digital to analog for a computer?
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.
How do analog sound systems compare to digital systems?
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.
Is sound from a speaker digital or analog?
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.
What are the advantages of a digital radio over an analog radio?
The advantages of digital radio over analog radio are digital radios get more channels than analog, they are clearer in sound and signal and have more additional features.
Why is microphone useful?
Original.It changes the sound (pressure waves in the air in the room) into a digital signal.Correction:It changes the sound pressure waves into an ANALOG signal. Any digital signal is the result of feeding the analog mic signal into an analog-to-digital converter, typically in a computer's sound card.Original.An electric guitar doesn't need a microphone because it makes a digital signal.Correction:A simple guitar with magnetic pickups creates an ANALOG signal from the motion of the strings, typically tens to low hundreds of millivolts. If you want a digital signal, you need: 1. Analog-to-digital processing in the guitar itself, or2. Analog-to-digital processing externally, such as a computer sound card.Original.An mp3 recording is a digital signal.
What is analog sound and example of analog sound?
analog audioRefers 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
How may analog media be converted to a digital format?
digital imaging (using digital cameras and scanners), sound cards, and analog video-capturing devices sample, compress, and convert analog media into a series of 0s and 1s (digital) signals for processing by a computer
What is digital analog?
Analog TV:Analog (or analogue) television encodes television picture and sound information and transmits it as an analog signal: one in which the message conveyed by the broadcast signal is a function of deliberate variations in the amplitude and/or frequency of the signal. All systems preceding digital television, such as NTSC, PAL or SECAM are analog television systems. Digital TV:Digital television (DTV) is the sending and receiving of moving images and sound by discrete (digital) signals, in contrast to the analog signals used by analog TV.
What converts a message from digital to analog and analog to digital?
An DAC convert digital signal to analog signal i.e Digital to Analog Converter. An ADC convert analog signal to digital signal i.e Analog to Digital Converter.
Converting sound from continuous to discrete format is done with a?
analog to digital converter
