The technology I chose is audio recording.
The original purpose of audio recording was to preserve and reproduce sound.Audio recordings include analog and digital recording.Analog recording refers to printing sound waves directly onto physical media (such as records and magnetic tapes).Digital recording is more familiar to me. It refers to converting sound signals into binary code and then processing them on a phone or computer, such as recording music or sound on a recording software.Sometimes I will record songs on my laptop or phone and process them.

The advent of this technology means that a song can be created without a band and singers.Here is a song that was created using this technique：https://youtu.be/e1xCOsgWG0M
