Über AVI-DateienOpus Audio
Audio FilesOpus is a versatile, open-source audio codec optimized for both speech and music at very low bitrates. It is the standard for WebRTC voice calls and excels at real-time communication.
Über OPUS-DateienVorteilsvergleich
AVI Vorteile
- 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.
OPUS Vorteile
- Best-in-class quality across the entire bitrate range.
- Royalty-free and patent-free.
- Ultra-low latency — suitable for live voice and music.
- Handles speech and music equally well — no need to switch codecs.
- Mandatory codec in WebRTC, so supported in every browser by design.
Einschränkungen
AVI Einschränkungen
- 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.
OPUS Einschränkungen
- Very low hardware decoder adoption — software-only on most phones.
- Older platforms (legacy Windows apps, old cars) may not play .opus files.
- Container semantics confusing — Opus lives inside Ogg, WebM, or MP4.
- Encoder tooling is less polished than AAC's commercial ecosystem.
