Which file format is known for compressing music while sacrificing some quality?

The MP3 file format is specifically designed for compressing audio files, including music, while sacrificing some quality. This compression allows for smaller file sizes, making it easier to store and share music without requiring as much storage space as lossless formats like WAV. The loss in quality is often imperceptible to the average listener, which is why MP3s became one of the most popular formats for music distribution, particularly in the digital age.

In contrast, WAV files are uncompressed and, therefore, retain the full audio quality at the expense of larger file sizes. MIDI files are not audio recordings but rather a set of instructions for generating sounds, and HTML is a markup language for creating web pages, not related to audio compression. Thus, MP3 is the most suitable choice for audio compression with a trade-off in quality.
