Abstract
A plural-channel audio signal (e.g., a stereo audio) is processed to modify a gain (e.g., a volume or loudness) of a speech component signal (e.g., dialogue spoken by actors in a movie) relative to an ambient component signal (e.g., reflected or reverberated sound) or other component signals. In one aspect, the speech component signal is identified and modified. In one aspect, the speech component signal is identified by assuming that the speech source (e.g., the actor currently speaking) is in the center of a stereo sound image of the plural-channel audio signal and by considering the spectral content of the speech component signal.
Claims25
A method comprising:
- obtaining a plural-channel audio signal including a speech component signal and other component signals;
- and
- modifying the speech component signal based on a location of the speech component signal in a sound image of the audio signal.
A method comprising:
- obtaining an audio signal;
- obtaining user input specifying a modification of a first component signal of the audio signal;
- and
- modifying the first component signal based on the input and a location cue of the first component signal in a sound image of the audio signal.
A system comprising:
- an interface configurable for obtaining a plural-channel audio signal including a speech component signal and other component signals;
- and
- a processor coupled to the interface and configurable for modifying the speech component signal based on a location of the speech component signal in a sound image of the audio signal.
A method comprising:
- obtaining a plural-channel audio signal including a speech component signal and other component signals;
- and
- modifying the other component signals based on a location of the speech component signal in a sound image of the plural-channel audio signal.
