Limitaciones
AAC Limitaciones
- Patent-encumbered — encoders have licensing fees, which is why open alternatives (Opus, Vorbis) exist.
- Slightly more complex to encode than MP3.
- Raw .aac streams carry no seek index — tooling often prefers M4A/MP4 containers.
- Lossy — not suitable for archival or studio production.
WV Limitaciones
- Small ecosystem.
- Hybrid mode complexity.
- Hardware support limited vs FLAC.
