Transport Stream files from digital television broadcasts carry audio compressed with MPEG-2 Audio Layer II (common in DVB) or AC3/E-AC3 (standard in ATSC) alongside the video stream. Converting TS to FLAC extracts and re-encodes this audio using the Free Lossless Audio Codec, which compresses audio by 40-60% without discarding any data — every decoded sample is preserved exactly.
FLAC is the gold standard for lossless audio archival. When you extract audio from broadcast recordings, FLAC preserves the full decoded quality of the source while keeping files significantly smaller than uncompressed WAV or AIFF. It is open-source, patent-free, and supported by virtually every audio player and DAW on every platform.
FFmpeg demuxes the TS container by reading Program Association and Program Map tables to identify audio elementary streams. The selected audio PID is reassembled from TS packets, decoded through the appropriate decoder (MPEG-2 Audio, AC3, or E-AC3), and the resulting PCM samples are compressed using FLAC's LPC (Linear Predictive Coding) with Rice coding. Compression level 5 (default) provides an optimal speed/size tradeoff. The output includes Vorbis comment metadata if available.
FLAC is bit-perfect lossless — the decoded output is sample-identical to the PCM produced by decoding the broadcast audio. The quality ceiling is determined by the broadcast source: MPEG-2 Audio at 192-384 kbps for DVB, or AC3 at 384-640 kbps for ATSC. FLAC faithfully preserves whatever the broadcast delivered.
