FLAC audio, which stands for Free Lossless Audio Codec, is a audio compression format that provides a lossless compression for digital audio. FLAC was designed to offer high-quality audio compression while preserving the original audio data without any loss in sound quality. FLAC audio has gained popularity over the years and is now recognized as a reliable and efficient lossless audio compression format. It has particularly captured the attention of music enthusiasts and professionals in the recording and music production industry. These s is for speech about low level FLAC audio syntax elements and their viewing and analyzing with Verinext Bitstream Analyzer.
