FLAC vs MPEG
Ein detaillierter Vergleich von FLAC Audio und MPEG Video — Dateigröße, Qualität, Kompatibilität und welches je nach Workflow zu wählen ist.
FLAC Audio
Audio FilesFLAC is an open-source lossless audio codec that compresses audio to roughly 50-60% of its original size without any quality loss. It is the preferred format for audiophiles and music archival.
Über FLAC-DateienMPEG Video
Video FilesMPEG is an early digital video standard that formed the basis for later formats like MP4. MPEG-1 and MPEG-2 files are common in DVD rips and older digital video archives.
Über MPEG-DateienVorteilsvergleich
FLAC Vorteile
- Lossless — decoded audio is bit-exact identical to the source.
- 40-60% smaller than uncompressed WAV/AIFF.
- Free, patent-free, open-source reference implementation.
- Built-in error detection via MD5 checksums.
- Streaming-friendly — seek tables let you jump to any timestamp instantly.
MPEG Vorteile
- Universal playback on every OS, player, and DVD/TV hardware since 1995.
- Proven, well-documented — three decades of spec refinement and tooling.
- Best-in-class for broadcast — Transport Streams carry multiple channels, error correction, and PSI/SI metadata.
- Low CPU decoding — even 1990s hardware can handle MPEG-1/2.
Einschränkungen
FLAC Einschränkungen
- File sizes still large compared to lossy codecs (5-10× bigger than AAC for same audio).
- Not suitable for low-bandwidth scenarios like streaming on mobile data.
- Older MP3 players and car stereos may not decode FLAC.
- Slower to encode than lossy codecs.
MPEG Einschränkungen
- Aging codec — MPEG-2 is 2-3× larger than H.264 at equivalent quality.
- Patent licensing still active for some MPEG-2 patents in certain territories.
- Consumer devices rarely default to .mpg — everything ships as .mp4 today.
- No modern features (HDR, HEVC, AV1) inside classic MPEG Program Streams.

Both are lossless with similar compression ratios. Use FLAC for universal compatibility and open-source support. Use ALAC if you are fully invested in the Apple ecosystem since iTunes and Apple Music handle ALAC natively.
