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 ...
