  Digital Audio Formats
Many different digital audio formats and different software are used to create, store and manipulate these files, the good news for consumers is that there is also a wide range of devices and products available that support multiple formats.
Because some audio files are open standards and some are proprietary, chances are we'll be seeing a wide variety of digital audio formats for some time to come.
Digital audio comes in many different formats, and multiple formats will be a fact of life for the foreseeable future.

 Digital Audio Formats
The format of a digital audio file refers to the type of audio data within the file.
When PCM audio is transmitted, each “1” is represented by a positive voltage pulse and each “0” is represented by the absence of a pulse.
Even though MPEG Audio formats are based on open standards and widely used, many companies continue to develop proprietary digital audio formats.

 Basic Concepts of Digital Audio
The only time the audio needs to be sent to a Digital to Analog Converter for playback (except for monitoring during mixing, which doesn't get saved) is when the listener puts the final CD in his or her CD player.
Digital audio is a bit different, because it is analog audio converted to binary data.
Digital audio data must be converted to analog form in order for it to be heard through amplifiers and speakers (in other words, it must be processed by a Digital to Analog Converter).

 Digital Audio Theory
Digital audio is better than other audio, digital video is better than other video, etc. If you are like a lot of us, you are wondering just what digital audio is, and whether it really is better.
Digital, or digitized, sound is easier to reproduce and manipulate without loss in quality.
Digital is not necessarily better, but it is different, and offers advantages to engineers and end users that will increase its dominance in the coming years.

 musiq.com Digital Audio tutorial
Digital audio is a stream of bytes which contain amplitude (volume) data.
Consequently, a second of digital audio can represent any combination of frequencies, to the limit of both the sampling rate (how many of these amplitudes per second) and the bit depth (how much data represents each amplitude).
Taking standard CD audio, we have a format which transmits 44,100 samples per second with a bit depth of 16 bits.

 Tutorial - Basics - Part 1 - Digital Audio
Digital files can be copied as many times as you want, with no loss in quality, and they can be burned to an audio CD or shared via the Internet.
Digital audio files can also be edited much more easily than analog tapes.
Modern compressed audio files use sophisticated psychoacoustics algorithms to represent the essential frequencies of the audio signal in far less space.

 Television Production: Digital Audio for TV and Radio
This is possible because of the precise timing pulses associated with digital audio and the fact that digital signal is comprised of "0s"and"1s." These represent simple positive and negative voltages that are not close to each other in value (so as to get easily confused or muddled along the line).
Actually, an occasional full-scale digital sample (to the top of the red range above) is considered inevitable; but, a regular string of "top of the scale" occurrences means that the digital audio levels are too high and you are losing audio information.
People working with digital audio should at least be aware of the potential problem, and before a video project is started, consult an engineer about the possible problems that could arise in the conversion process.

 Digital Audio
Also, when the digital signal (the stream of binary digits representing the quantized samples) is sent to the DAC to be re-converted into a continuous electrical signal, the sound coming out of the DAC will contain spurious high frequencies that were created by the sample and hold process itself.
The main problem with aliasing is that it can add frequencies to the digitized sound that were not present in the original sound, and unless we know the exact spectrum of the original sound there is no way to know which frequencies truly belong in the digitized sound and which are the result of aliasing.
Since a digital representation of sound is just a list of numbers, any list of numbers can theoretically be considered a digital representation of a sound.
