Introduction to Audio Properties

Audio is a professional term. All sounds that humans can hear can be called audio. Of course, it also includes noise. After the sound is recorded, whether it is speaking, singing, or musical instruments can be processed through digital music software, or it can be made into a CD. At this time, all the sounds have not changed, because the CD is originally a type of audio file , And the audio is just the sound stored in the computer.

If there is a computer and the corresponding audio card is the sound card we often say, we can record all the sound, and the acoustic characteristics of the sound, such as the sound level, can be stored in the form of computer hard disk files. Conversely, we can also play the stored audio file with a certain audio program to restore the previously recorded sound.
