MPEG-4 Audio
M4A (MPEG-4 Audio) is a file extension for audio files encoded with Advanced Audio Coding (AAC) or Apple Lossless Audio Codec (ALAC). It's known for delivering high-quality sound in a smaller file size compared to MP3 and is commonly used in Apple devices and software, such as iTunes and iPods.
MPEG Audio Layer III
MP3 (MPEG Audio Layer III) is a widely-used lossy audio compression format known for its ability to reduce file sizes while maintaining reasonable sound quality. Popularized in the late 1990s and early 2000s, it became the de facto standard for digital audio storage and playback, revolutionizing the music industry and the way we consume music.
