Over RA-bestandenVergelijking van sterke punten
AAC Sterke punten

- Universally supported on every smartphone, OS, and browser.
- Efficient on battery thanks to widespread hardware decoding.
- Scales from 8 kbps speech (HE-AACv2) to lossy-transparent 320 kbps.

RA Sterke punten

Beperkingen
AAC Beperkingen
- 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.
RA Beperkingen
- Proprietary and commercially abandoned.
- No modern player auto-installs RealAudio support.
- RealNetworks damaged its own brand with aggressive adware.
- Modern replacements (Opus, HE-AAC) outperform RA at every bitrate.
