Audio data compression works by removing bits from a digital audio file to reduce its size. Lossy compression removes “nonessential details” irreversibly (notably frequency content). Lossless compression removes “statistical redundancies” to reduce file size reversibly without impacting the audio.

Why is compression used for audio files?
Why is audio compression used in mixing? Compression is used in music to reduce the dynamic range of signals with loud and quiet elements so that both can be heard clearly. Compression is used in music to reduce the dynamic range of signals with loud and quiet elements so that both can be heard clearly.
Why is data compression used for video and audio content?
Compression enables you to reduce the amount of storage resources needed to store videos, saving costs. It also enables you to reduce the amount of bandwidth needed to transfer videos, providing a better user experience when media is accessed.
How compression can aid the storage of data images or sounds?
Simply put, compression methods crunch data - text, graphics, audio or video - into a computer-decipherable shorthand that's 10% to 99% of its original size. The data takes up less storage space and requires less bandwidth to be transmitted over the Internet.
How does compression affect audio quality?
Compressing to lossy formats such as MP3s will use a lower audio bitrate—meaning you will lose a good chunk of the audio file data. You'll get a much smaller file, making it easier to share and to play or stream, but you'll also lose some of the overall sound quality.
