Content-aware audio modes

摘要

An audio system for manipulating audio material for playback based on the content of the material includes an input for receiving input audio signals, an output for providing output audio signals to loudspeakers, and an audio processor that processes the input audio signals to produce the output audio signals. The audio processor determines a type of content represented by the input audio signals, selects a set of processing instructions to control the spatial presentation of the audio material based on the determined type, and applies the selected set of processing instructions to the input audio signals.

1. An audio system for manipulating audio material of an audio program for playback based on the content of the material, the system comprising:
an input for receiving input audio signals; an output for providing output audio signals to loudspeakers; and an audio processor that processes the input audio signals to produce the output audio signals, the audio processor configured to:
determine a type of content represented by the input audio signals;select a set of processing instructions to control the spatial presentation of the audio material based on the determined type; andapply the selected set of processing instructions to the input audio signals; wherein the processing instructions further:
control the spectral presentation of the audio material;maintain intelligibility of speech within the audio program while adjusting the overall volume of the program; andraise and lower the volume of speech sounds at a different rate than they raise and lower the volume of non-speech sounds in response to a total volume level being raised and lowered, respectively.
