Abstract
A vehicle audio system that includes a source of audio signals, which may include both entertainment audio signals and announcement audio signals, speakers for radiating audio signals, and spatial enhancement circuitry comprising circuitry to avoid applying spatial enhancement processing to the announcement audio signals.
Claims20
A vehicle audio system comprising:
- an input for receiving input audio signals;
- an announcement audio extractor configured to extract announcement audio content from the input audio signals and output the extracted announcement audio content and entertainment audio content remaining in the input audio signals after extraction of the announcement audio content;
- a spatial processor configured to receive the entertainment audio content from the announcement audio extractor and apply spatial processing to the entertainment audio content to output spatially processed entertainment audio content;
- and
- an output matrixer configured to
- receive the announcement audio content from the announcement audio extractor and the spatially processed entertainment audio content from the spatial processor, and
- combine the announcement audio content and the spatially processed entertainment audio content to generate output audio signals;
- and
- an output for providing the output audio signals.
6 more elements
A method for operating a vehicle audio system comprising:
- receiving input audio signals;
- extracting announcement audio content from the input audio signals;
- applying spatial processing to entertainment audio content remaining in the input audio signals after extraction of the announcement audio content;
- combining the extracted announcement audio content and the spatially processed entertainment audio content to generate output audio signals;
- and
- outputting the output audio signals.
3 more elements
A vehicle audio amplifier comprising:
- input terminals for receiving input audio signals;
- and
- an announcement audio extractor configured to extract announcement audio content from the input audio signals and output the extracted announcement audio content and entertainment audio content remaining in the input audio signals after extraction of the announcement audio content;
- a spatial processor configured to receive the entertainment audio content from the announcement audio extractor and apply spatial processing to the entertainment audio content to output spatially processed entertainment audio content;
- an output matrixer configured to
- receive the announcement audio content from the announcement audio extractor and the spatially processed entertainment audio content from the spatial processor, and
- combine the announcement audio content and the spatially processed entertainment audio content to generate output audio signals;
- an output amplifier stage configured to amplify the output audio signals;
- and
- output terminals for providing the output audio signals.
