Sobre los archivos RAComparativa de ventajas
FLAC Ventajas
- Lossless — decoded audio is bit-exact identical to the source.
- 40-60% smaller than uncompressed WAV/AIFF.
- Free, patent-free, open-source reference implementation.
- Built-in error detection via MD5 checksums.
- Streaming-friendly — seek tables let you jump to any timestamp instantly.
RA Ventajas
- Extremely low-bitrate streaming viable on 1990s modems.
- Historic archive value for late-1990s broadcasting.
- Codec variants for voice and music (RAC, cook, sipr).
Limitaciones
FLAC Limitaciones
- File sizes still large compared to lossy codecs (5-10× bigger than AAC for same audio).
- Not suitable for low-bandwidth scenarios like streaming on mobile data.
- Older MP3 players and car stereos may not decode FLAC.
- Slower to encode than lossy codecs.
RA Limitaciones
- 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.
