MP3 File

Context:
- It can (typically) store music, podcasts, or other audio content in a compressed form to reduce file size while maintaining a quality perceived to be close to the original uncompressed audio.
- It can (often) be played on a wide variety of digital audio players, computers, and smartphones.
- It can utilize psychoacoustic models to minimize or approximate the accuracy of specific sound components beyond most people's hearing resolution, reducing the file size significantly.
- It can be created by an MP3 Encoding System (which can allow for various settings, including bit rate, sampling rate, and channel mode to balance between audio quality and file size).
- It can support metadata such as ID3 tags, which store information like the track's title, artist, album, and more.
- It can be processed by an MP3 Processing File System.

Example(s):
- A podcast episode saved as an MP3 file with a 128 kbit/s bit rate.
- A music album downloaded from an online store in MP3 format.
- ...
Counter-Example(s):
- A WAV File, which typically contains uncompressed audio and therefore has a larger file size.
- An FLAC File, which is a lossless audio format offering compression without loss of quality.
