Audio compression with desirable attributes for factory automation
Xiaotang Chen, K. Lee, Y. K. Chan, Young-Dal Yu · 2002
With increasing factory automation application requiring multimedia content, compression technology for audiovisual content is needed to minimal bandwidth requirement. An audio compression scheme is presented in here and this scheme is characterized primarily by its fast encoding and decoding speed for high fidelity audio. The bit rate for this scheme is competitive to existing international standard for high fidelity audio compression. In the context of factory automation, the compression scheme presented in here has desirable attribute including preservation of high quantitative fidelity, fast encoding speed using off-the-shelf microcontroller with integer only computation for low cost applications, minimal codec delay to satisfy real time requirement, etc.
