Nomenclature of monitoring system-audio source

The sound source is the source of the sound. Without a sound source, there is no way to restore the sound with the sound system. The sound source has two meanings. First, it refers to the carrier that records the sound. Only when the sound is recorded on a certain carrier, can it be said that the sound on the carrier is restored by the audio equipment. These carriers are the source of the sound in the audio system. So it's called sound source. Another meaning of sound source refers to the device that plays the sound source carrier. Signals that are continuous in time and whose amplitude changes continuously with time are called analog signals (for example, sound waves are analog signals, and the current and voltage signals transmitted in the audio system are also analog signals), and the audio source that records and processes analog signals is an analog sound source, such as magnetic tape / Deck, LP / LP record player. The signal recorded and processed by the analog audio source is the original face of the sound (accurately speaking, it should be an electrical signal converted from the sound), which can be directly amplified by a traditional amplifier, which is convenient and direct to process; digital audio source recording and processing are all 0 The abstract binary data stream formed by the permutation and combination of 1 is very unintuitive. Sound waves are analog and cannot be used directly for digital audio sources. They must be converted to digital signals through conversion equipment before they can be recorded on a digital audio source carrier. During playback, the data read by the digital audio source device cannot be directly amplified by a traditional amplifier, and must be converted to an analog signal first. It can be seen that the digital audio signal processing process is much more complicated. However, the advantages of digital audio sources are outstanding: the signal-to-noise ratio and dynamic range are far superior to analog audio sources. The quality of the signal does not deteriorate after multiple replications and multiple transmission links. This analog audio source cannot be done anyway.
