AVI vs WAV
A detailed comparison of AVI Video and WAV Audio — file size, quality, compatibility, and which format to choose for your workflow.

About WAV filesStrengths Comparison
AVI Strengths
- Simple, well-documented format — trivial for any video library to parse.
- Universal Windows playback since Video for Windows in 1992.
- Low encoding overhead — interleaved structure is fast to write.
- Works with any codec technically, including modern ones.
WAV Strengths
- 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.
Limitations
AVI Limitations
- Aging container — no native support for chapters, subtitles, or multi-audio selection.
- File-size limits (2 GB original, 4 GB with OpenDML) break for HD content.
- Variable-framerate video causes sync drift.
- Larger than equivalent MP4 or MKV due to container overhead.
- Poor support on iOS and Android.
WAV Limitations
- 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.
