Abstract
A method and system dynamically adjusts the audio of an audio and video signal to improve its overall sound quality and dialog intelligibility. Some embodiments use gain, equalization, audio signal compression and spatial enhancement (reverb) on individual channels of a multichannel audio signal.
Claims20
A method comprising:
- receiving a multichannel audio signal including a center channel;
- processing each channel of the multichannel audio signal to enhance intelligibility of dialog in the multichannel audio signal upon playback of the multichannel audio signal, including:
- processing the center channel of the multichannel audio signal further includes raising the dialog's lowest level and lowering the dialog's loudest level by compressing the center channel's dynamic range by a first ratio;
- in parallel with said processing of the center channel, processing a second channel of the multichannel audio signal by compressing the second channel's dynamic range by a second ratio, the second ratio being higher than the first ratio;
- and
- passing the processed audio channels to a device.

A system comprising:
- an input for receiving a multichannel audio signal including a center channel;
- a plurality of processing modules, each processing module individually processing a channel of the multichannel audio signal to enhance intelligibility of dialog in the multichannel audio signal upon playback of the multichannel audio signal;
- a first processing module configured to process the center channel of the multichannel audio signal by raising the dialog's lowest level and lowering the dialog's loudest level by compressing the center channel's dynamic range by a first ratio;
- a second processing module, in parallel with the first processing module, configured to compress the second channel's dynamic range by a second ratio, the second ratio being higher than the first ratio;
- and
- an output for passing the processed audio channels to a device.

A method comprising:
- receiving a multichannel audio signal including a center channel;
- processing each channel of the multichannel audio signal to enhance intelligibility of dialog in the multichannel audio signal upon playback of the multichannel audio signal, including:
- processing the center channel of the multichannel audio signal by adjusting equalization of the center channel by raising the center channel's signal level in an audio frequency range of human speech in comparison to the center channel's signal level outside the audio frequency range of human speech, and
- in parallel with said processing of the center channel, clearing the audio frequency range of human speech in a second channel of the multichannel audio signal by attenuating the second channel's signal level in the audio frequency range of human speech in comparison to the second channel's signal level outside the audio frequency range of human speech;
- and
- passing the processed audio channels to a device.
