Audio Loudness Adjustment

摘要

Audio loudness adjustment techniques are described. In one or more implementations, primary and secondary sound data originating as part of an audio signal is adjusted. For example, a loudness of the sound data is adjusted. To do so, the loudness, which indicates a sound intensity of the primary and secondary sound data, is determined. Adjustments are then computed for at least a portion of the audio signal based on a target dynamic range parameter, which defines a desired difference between the loudness of the primary and secondary sound data respectively. Based on the computed adjustments, a variety of actions may be performed, such as applying the adjustments to the audio signal to generate an adjusted audio signal in which the primary and secondary sound data substantially have the desired loudness difference. Further, a preview of the adjusted audio signal may be updated in real-time for display in a user interface.

1. In a digital audio environment to adjust primary and secondary sound data originating as part of an audio signal by one or more computing devices, a method comprising:
determining loudness of the audio signal by the one or more computing devices, the loudness indicating a sound intensity of the primary and secondary sound data; computing adjustments to the loudness by the one or more computing devices for at least a portion of the audio signal based on a target dynamic range parameter that defines a desired difference between the loudness of the primary and secondary sound data respectively; and applying the computed adjustments by the one or more computing devices to the audio signal to generate an adjusted audio signal in which the primary and secondary sound data substantially have the desired difference in the loudness.
