WAV vs Y4M
Ein detaillierter Vergleich von WAV Audio und YUV4MPEG2 — Dateigröße, Qualität, Kompatibilität und welches je nach Workflow zu wählen ist.
WAV Audio
Audio FilesWAV is an uncompressed audio format that preserves full audio fidelity. Files are large but provide lossless, CD-quality sound. It is the standard working format in audio production and editing.
Über WAV-DateienYUV4MPEG2
Video FilesYUV4MPEG2 (Y4M) is a simple uncompressed video format that stores raw YUV pixel data with a minimal header. It is widely used as an intermediate format for video processing and quality benchmarking where no compression artifacts are acceptable.
Über Y4M-DateienVorteilsvergleich
WAV Vorteile
- Bit-perfect, uncompressed audio — the professional studio standard.
- Universally supported for playback, editing, and analysis.
- No re-encoding penalty — edit and save repeatedly with zero quality loss.
- Simple internal structure — easy to parse programmatically.
- Supports up to 32-bit float and 384 kHz sample rates.
Y4M Vorteile
- Uncompressed raw YUV — codec benchmark truth.
- Dead-simple header.
- Universal codec development support.
Einschränkungen
WAV Einschränkungen
- Enormous file sizes — 10 MB per minute for CD-quality stereo.
- 4 GB size limit for standard WAV (RF64/W64 variants extend it but break compatibility).
- No native support for cover art or rich metadata.
- Impractical for casual listening or bandwidth-constrained delivery.
Y4M Einschränkungen
- Enormous file sizes.
- Development-only — not for consumption.
- No metadata beyond basic stream params.
