Immersive Soundfield Rendition (ISR) system is an in-house low bit rate multi-channel audio codec ( 5.1-channel ). The high quality multi-channel audio compression tool is engineered with state-of-the-art patent pending algorithm namely, Multi Band Temporal Amplitude Coding (MBTAC). ISR emphasizes the accurate reproduction of multi band temporal envelope of Multichannel data. The ease of scalability of the surround image, between 2 kbit/s and 12 kbit/s, and its high quality audio with feature rich add-ons make the tool user friendly. A conventional stereo encoder can be upgraded to a multi-channel encoder with the aid of an associated low overhead ISR bitstream.
