NEW SOLID Pro 5s Wireless Bluetooth Earphones

udio is a technical term that has been used generally to describe sound-related devices and their functions in the audio range. All sounds that humans can hear are called audio, which may include noise, etc. After the sound is recorded, whether it is speaking, singing, or musical instruments, it can be processed by digital music software, or it can be made into a CD. At this time, all the sounds remain unchanged, because CDs are originally a type of audio files. And audio is just the sound stored in the computer. If there is a computer coupled with a corresponding audio card - that is, the sound card we often say, we can record all the sounds, and the acoustic characteristics of the sound, such as the level of the sound, can be stored in the form of computer hard disk files
