Problems solved by technology

However, the 5.1-channel 6-channel audio processor or the 7.1-channel 8-channel audio processor currently on the market cannot meet the needs of the giant-screen theater with an all-sky sound field of 11.1 channels and a 13.1-channel movie stereo system. It also cannot achieve seamless connection with the digital cinema server, which eventually leads to the inability of the TMS digital cinema management system to uniformly manage the digital cinema audio processor

Abstract

The invention discloses a digital cinema audio processor with sixteen channels. To-be-processed audio signals enter an audio decoding unit through an audio input unit to be decoded or enter an A / D conversion unit to be subject to analog-to-digital conversion, digital audio signals obtained after the processing are output to a DSP processing unit, the DSP processing unit processes the digital audio signals by combination with a control unit, and then the digital audio signals are subject to digital-to-analog conversion and are output through an audio output unit. The digital cinema audio processor can be in seamless connection with a server of a TMS digital cinema management system through a communication interface unit, is provided with the sixteen channels, can meet 3D and huge-screen film playing requirements and have the advantages of being high in reliability, good in sound effect and quick in data processing speed.

Description

technical field [0001] The invention relates to audio processing, in particular to a digital cinema audio processor with sixteen channels. Background technique [0002] 3D and giant-screen movies are widely favored by audiences for their perfect sound effects and visual effects. For example, the 11.1-channel and 13.1-channel movie stereo systems for all-sky sound fields can create a wider three-dimensional sound field, so that every audience can enjoy Immersive, feel the perfect 3D sound effects. [0003] 3D and giant screen movies have an increasing demand for multi-channel, and the requirements for audio technology are also getting higher and higher. However, the 5.1-channel 6-channel audio processor or the 7.1-channel 8-channel audio processor currently on the market cannot meet the needs of the giant-screen theater with an all-sky sound field of 11.1 channels and a 13.1-channel movie stereo system. It also cannot realize the seamless connection with the digital cinema ...
