Abstract: Audio enhancement based on video and/or other characteristics. Information associated with a media signal is employed to modify an audio signal portion thereof. When undergoing playback, a modified audio signal enhances a perceptual experience for a user (e.g., a listener, a viewer, etc.). Based on information from any desired source, an audio signal may undergo certain modification so that, when played back, the modified audio signal enhances a user's perceptual experience. For example, information related to a scene (e.g., foreground, background, etc.) of a media signal (e.g., extracted from an image frame of a video signal thereof) may be used to modify the audio effects of the audio signal portion of the media signal. In addition, information related to the position of an audio source (e.g., such as a location of a speaker/character in a film) may be used to modify the audio signal to reflect that audio source's location.
