What is a Audio file?
An audio file is a digital format designed to store sound recordings, ranging from music and podcasts to voice memos. Popular extensions include .mp3, .wav, .flac, and .m4a. Internally, files may contain compressed streams (MP3, AAC, OGG) or uncompressed waveforms (WAV, AIFF). Metadata often stores track names, album art, and lyrics. Formats differ in purpose: MP3 for universal compatibility, FLAC for lossless archiving, and WAV for professional editing. Audio files are the backbone of digital music libraries and streaming services.
