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 resolution.
Digital and analog differ in both the methods of transfer and storage, as well as the behavior exhibited by the systems due to these methods. The dynamic range capability of digital audio systems far exceeds that of analog audio systems. Consumer analog cassette tapes have a dynamic range of between 50 and 75 dB.
Digital audio is sound (often music or speech) which is recorded (born-digital) or converted from analog sources and stored in a digital format. Digital audio can be stored on a variety of storage media, including compact disc, audio CD, audio DVD, DAT tape, or as a computer file. Playing equipment decodes the stored signal.
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.
Sound recording and reproduction is the electrical, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. The two main classes of sound recording technology are analog recording and digital recording .
A digital representation expresses the audio waveform as a sequence of symbols, usually binary numbers. This permits signal processing using digital circuits such as digital signal processors, microprocessors and general-purpose computers. Most modern audio systems use a digital approach as the techniques of digital signal processing are much ...
