Scala Technology

scalable audio coding solutions

Scala audio compression algorithms achieve efficient coding with fine-grain bitrate scalability, with applications in internet audio streaming, mobile multimedia communication, and audio archiving.

This scalable technology offers the following advantages over conventional coding approaches:

• Fine-grain scalability, where useful increases in coding quality can be achieved with small increments in bitrate

• High coding efficiency, competitive with fixed-bitrate coding schemes used in MPEG-2/4 AAC

• High computational efficiency - our coding scheme benefits from a simple single-pass quantisation stage

• Error resilience - Scala bitstreams are robust against transmission errors.

Windows evaluation software is available to demonstrate Scala's error-resilient scalable coding technology and compare performance with other codecs.
