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.
Recording. The analog signal is transmitted from the input device to an analog-to-digital converter (ADC).; The ADC converts this signal by repeatedly measuring the momentary level of the analog (audio) wave and then assigning a binary number with a given quantity of bits (word length) to each measurement point.
Digital Up to 13 hours on a standard 80-minute MiniDisc. Up to 45 hours on a 1 GB Hi-MD (MiniDisc) Digital audio player: Digital Roughly 186 hours of playback per 10 GiB, assuming an average bitrate of 128 kbit/s. Roughly 372 hours with 64 kbit/s and roughly 74 hours with 320 kbit/s. DVD: Digital
If an audio signal is analog, a digital audio system starts with an ADC that converts an analog signal to a digital signal. [b] The ADC runs at a specified sampling rate and converts at a known bit resolution. CD audio, for example, has a sampling rate of 44.1 kHz (44,100 samples per second), and has 16-bit resolution for each stereo channel.
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. Note on the use of analog compared to digital in this list; the definition of digital used ...
As digital recording developed, so did a controversy commonly known as the analog versus digital controversy. Audio professionals, audiophiles, consumers, musicians alike contributed to the debate based on their interaction with the media and the preferences for analog or digital processes. [46]

Audio or video Digital or analog Description Audio only: Analog: Often unmarked on consumer audio equipment since it is so common, or labelled with headphones symbol or as "line out". Computers and other equipment sometimes use Microsoft-Intel color coding scheme, especially when there are multiple input/output plugs. 3.5 mm TRS minijack RCA ...
