Analog Audio

Until relatively recently the analog format was the only method used to record music and sound. Although the digital world has surely taken over much of what analog used to, some still prefer the analog format over digital.

In analog audio the recorded sound resembles the original sound in a continuous way. If you were to zoom into an analog signal you would find that the signal was smooth.

Magnetic tape is an example of a method used to record analog audio. The electric signal polarizes the magnetic particles on the tape in a pattern, which resembles the original sound. In analog audio frequency is the time component and amplitude is the level component.
