What is a .FLAC file?
The FLAC format (short for Free Lossless Audio Codec) is an audio format that uses lossless compression, so every detail is preserved exactly with no loss of quality. It acts as a container that packages audio together for playback. FLAC files open natively in every modern web browser.
