Most of us listen to music in MP3 format. But do you know what MP3 is? If you don't know which audio format to choose when exporting and saving a piece of music, read this post thoroughly. It tells you what MP3 is and shows you how to play it successfully. Let's dive in now!

What is MP3 and How Does It Work?

MP3 is a coding format for digital audio initially released in 1991. It contains an elementary stream of MPEG-1 Audio or MPEG-2 Audio encoded data without other complexities of the MP3 standard. MP3 uses lossy data compression to encode data, which greatly reduces file sizes compared to uncompressed audio files.

How does it work? It compresses audio by reducing the accuracy of certain components of sound that are considered to be beyond the hearing capabilities of most people. The remaining audio information is then recorded with MDCT and FFT algorithms. It can commonly achieve a 75 to 95% reduction in size, making it popular with people around the world.
