Digital audio is a representation of sound recorded in, or converted into, digital form. In digital audio, the sound wave of the audio signal is typically encoded as numerical samples in a continuous sequence. For example, in CD audio, samples are taken 44,100 times per second, each with 16-bit sample depth. Digital audio is also the name for ...
Sound quality is typically an assessment of the accuracy, fidelity, or intelligibility of audio output from an electronic device. Quality can be measured objectively, such as when tools are used to gauge the accuracy with which the device reproduces an original sound; or it can be measured subjectively, such as when human listeners respond to ...
Timeline of audio formats. An audio format is a medium for sound recording and reproduction. The term is applied to both the physical recording media and the recording formats of the audio content —in computer science it is often limited to the audio file format, but its wider use usually refers to the physical method used to store the data.
In mass communication, digital media is any communication media that operates in conjunction with various encoded machine-readable data formats. Digital content can be created, viewed, distributed, modified, listened to, and preserved on a digital electronic device, including digital data storage media (in contrast to analog electronic media ...

The ratio of the amplitude of the loudest possible undistorted sine wave to the root mean square (rms) noise amplitude.
Digital radio is the use of digital technology to transmit or receive across the radio spectrum. Digital transmission by radio waves includes digital broadcasting, and especially digital audio radio services .
Digital audio compact discs (using PCM) were introduced in 1982. Starting in 1985, the medium was adapted for the storage of computer data via the Yellow Book CD-ROM standard and the High Sierra Format (which evolved in ISO 9660). The Macintosh 128K (1984) and Atari ST (1985) could produce digital audio via software. Without dedicated audio ...
