A digital audio system starts with an ADC that converts an analog signal into a digital signal. The ADC operates at the specified sampling rate and converts it to a known bit resolution. For example, music CDs have a sampling rate of 44.1 kHz (44,100 samples per second) and a 16-bit resolution for each stereo channel. Unclassified analog signals must pass through the filter. anti-aliasing Pre-conversion to prevent distortion caused by audio signals with frequencies above the Nyquist frequency.
Digital audio may be stored or transmitted. Digital audio can be stored on a CD. Digital audio players, hard drives, USB drives or other digital storage devices can change the number of signals using numbers that may be filtered or enforced. Sample conversion rates may include sampling and sampling. (downsampling) to correspond to signals encoded with different sampling rates into pre-processing sampling rates. Audio compression techniques such as MP3, Advanced Audio Coding, Ogg Vorbis or FLAC are often used to reduce the file size. Digital audio is available through digital audio systems such as AES3 or MADI. Digital audio can be used over the network using voice over Ethernet, IP or standard audio and other streaming systems.
For digital audio playback, it must be converted to an analog signal with DAC, which may use oversampling.
In digital audio the sound of analog signals is converted into analog signals into digital signals. Typically, pulse code modulation can be modified and used for computer, audio, host devices and other devices when listening to music from speakers or speakers. (Or let someone else listen to the music of the song), and the analog-digital signal (DAC) returns to the analog signal through the amplifier and sends it to the speaker.
Digital audio systems consist of components of compression, storage, processing and transmission. Converting to number format, storage, transport, and real-time audio access. Unlike analogue audio, which makes copies of recordings lose production and reduces signal quality, when using digital audio, they can reproduce an unlimited number of copies without compromising signal quality.
