Format Details
MP3
MP3 (MPEG Audio Layer 3) is the world's most popular digital audio format, developed by the Moving Picture Experts Group in the early 1990s. It uses psychoacoustic lossy compression to dramatically reduce file sizes while retaining audio quality that is perceptually adequate for most listeners. MP3 transformed the music industry by making digital music portable enough to share over the internet and store on devices with limited storage.
FLAC
FLAC (Free Lossless Audio Codec) is an open-source audio format that compresses audio without any loss of quality, allowing perfect bit-for-bit reconstruction of the original recording. It typically reduces file sizes by 40-60% compared to uncompressed WAV while remaining completely lossless. FLAC is the format of choice for audiophiles, music archivists, and mastering engineers who require studio-quality audio fidelity in a manageable file size.
