FLAC (Free Lossless Audio Codec) preserves audio perfectly at roughly half the size of uncompressed PCM. DivX movie files typically contain MP3 audio at 128-192 kbps or AC3 5.1 surround at 384-640 kbps. Converting DivX to FLAC extracts and decodes this audio into a lossless archival format — useful as a master copy from which you can later transcode to any lossy format without cumulative quality degradation.
FLAC provides lossless preservation of the decoded DivX audio in a widely supported open format. Android, Linux, Sonos, and most modern media players handle FLAC natively. Having a FLAC master means you can transcode to MP3, AAC, OGG, or any other format later without the quality loss of double-compression that occurs when transcoding directly between lossy formats.
The MP3 or AC3 audio stream is extracted from the DivX AVI container, decoded to raw PCM samples, and encoded with the FLAC codec using linear prediction and entropy coding. FLAC compression levels 0-8 trade encoding speed for file size (level 5 is default). Multichannel AC3 5.1 can be preserved as 6-channel FLAC or downmixed to stereo.
FLAC output is bit-identical to the decoded PCM from the DivX audio stream. No quality is lost in the FLAC encoding step. The limitations come from the original DivX audio codec — MP3 at 128 kbps has already discarded high-frequency content that FLAC cannot restore.
