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.
When digital values are converted to create an analog sound, the term used is Digital-to-Analog converter.
An ADC, or analog to digital decoder, is used to "translate" analog signals into digital signals. An analog signal can take on any value, such as 0.1V, 0.5V, 4.12V, 5V and so on. A digital signal on the other hand can either be "high" or "low", 1 or 0. A computer can only work with digital signals, and therefore you need to convert an analog signal into a digital signal in order for the computer to be able to work with it. This is what you do when you record sounds or music. Sound is an analog signal and had to be converted with an ADC to a digital signal before it can be used in a compter or stored on a CD. A DAC, or digital to analog decoder is the oposite of the ADC. Here the digital signal is converted into an analog signal. This is what happens when you play music from a CD-plate. On a CD there are a number of holes, which each translates as a 0 or 1. These are read with a laser beam which is reflected back into a receiver whenever the laserbeam hits a hole. This then counts as a 1. When the disk is spinning it produces a stream of 1s and 0s, which togerther form a binary string, such as 00010111011101. The DAC then converts this value into a analogue signal, such as 1.1V, which is then used to power your speaker and produce audible sound.
This is essentially the same question as the difference between analog and digital. With analog electronics a voltage is used to represent (or to be an analogy for) some physical attribute in the real world. So for an analog transmission, at its simplest, a sound signal (say) is converted to a voltage, the voltage sent down a cable, then at the other end the voltage converted back into sound with a loudspeaker. With a digital system, the physicial attribute is measured and sent as a series of numbers, the numbers being converted to binary. For a digital transmission, the sound signal is converted to a series of numbers, sent as binary, and converted back to a sound signal at the other end. The advantages of digital is that it makes multiplexing much easier - making it easier to put many signals down the same physical cable. It also makes compressing the signal much easier - this is particularly effective for digital television transmission; 30-40 digital channels can be sent over the same bandwidth as 4 or 5 uncompressed analog channels. Also, digital is much more resiliant against noise - the digital receiver has to make a decision about each bit - is it there or not; noise can be pretty extreme before this becomes impossible, with analog, once noise is added its very difficult to remove it. The historical disadvantage of digital is that digital encoding and decoding equipment was expensive compared with the analog. Over the last 10 years or so, digital electronics has become much cheaper and more powerful.
An analog sensor is a device that measures an analog quality (such as temperature, wind speed, sound frequency or velocity). Many of us fail to recognize the difference between qualitative and quantitative measurements. Quantitative descriptors are actually just the result of counting something; seventeen marbles, five folding chairs, three apples... Qualitative descriptors are the result of estimating something; eight cups of sliced apples, a five pound bag of marbles, the current room temperature. When we use a scale to measure something, it's called "qualitative"... or analog. Converters are available that allow a computer to achieve a close approximation of an analog measurement, but for the computer to use the value it must first be converted to a digital signal. Inside the computer, that digital signal is all ones and zeroes, but many of them can be put together to represent a very large number. If that doesn't help, perhaps a basic physics class or even a computer "digital logic" class might be beneficial.
we often confuse our-self with continuous time and analog signals. An analog signal is a signal which can take any amplitude in continuous range that is signal amplitude can take infinite values on the other hand a digital signal is one whose amplitude can take only finite numbers of values THE TERM CONTINUOUS SIGNAL AND DISCRETE SIGNAL CLASSIFY THE SIGNALS ALONG THE TIME (i.e. horizontal axis) where as THE TERM ANALOG AND DIGITAL SIGNAL CLASSIFY THE SIGNAL ALONG THE AMPLITUDE (i.e vertical axis)
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.
A computer only reads information in digital coding (binary) a truly analog signal would not register in a computer.
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
Sound can be both digital and analog. In analog sound, waveforms are continuously varying, while in digital sound, the waveforms are represented by discrete binary numbers. Most modern audio technologies, such as CDs and MP3s, use digital sound, while older mediums like vinyl records use analog sound.
Because our brains lack the capability to de-code digital signals. Therefore, any digital sound must be converted to analogue (and be within a specific frequency range) for us to hear it.
Information about a digital to analog converter can be found on the site Hardware Secrets which divulges that real world signals such as light and sound can be converted into digital signals by a circuit called ADC (Analog-to-digital converter) so that the information, once converted, can be processed and stored digitally.
Analog signals, such as sound or light, are converted into digital form through a process called analog-to-digital conversion. This process involves quantizing the continuous analog signal into discrete, digital values represented by binary numbers. Once in digital form, the signal can be processed, stored, and transmitted more efficiently and accurately.
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.
Because in order to preserve the original sound, a digital sampling rate must be twice the frequency of the analog signalAnalog data is smooth and continuous, where as digital data, such as the binary data used in computers, has distinct gradations. The process of producing digital data by measuring data at a series of representative points is called sampling.
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.
