MPEG Surround - high-quality surround sound at stereo bit-rates
MPEG Surround is a new, feature-rich open standard compression technique for multi-channel audio signals. Operating on top of any core audio codec such as AAC, HE-AAC and MPEG-1 Layer II, the system provides an unrivaled set of benefits including:
- High-quality multi-channel audio including 5.1 and 7.1 channel loudspeaker set-ups
- Surround sound at bit-rates as low as 64 kb/s or below
- Compatible with existing stereo devices and services
- Subjective audio quality substantially better than matrixed surround formats
- Virtual surround sound on-the-go with regular stereo earphones
- Cost-effective way to expand any stereo infrastructure to multi-channel usage
- Wide scalability in terms of bit rate
- Compatibility with matrixed surround stereo signals
In combination with HE-AAC, MPEG Surround can carry a five or seven channel surround program at a total bit rate of 64 kb/s or less.
MPEG Surround has been adopted by various application standards such as World DMB (DAB, DAB+, DMB), ISDB-Tmm, DVB, DRM+, AT-DMB, DLNA, OIPTV and ATIS-IFF.
MPEG Surround Evaluation and Commercial Software are available from Fraunhofer IIS and other vendors.
