Sample MP3 Audio File

MP3 (MPEG Audio Layer 3) is a popular compressed audio format that typically have the ".mp3" extension. MP3 uses lossy compression, meaning some original data is lost during compression. MP3 files are much smaller than uncompressed audio formats like WAV, typically about 1/10th the size. While not as high quality as uncompressed formats, MP3s can still provide good sound quality, especially at higher bit rates.
