SYSTEM AND METHOD FOR DYNAMICALLY ADAPTING PLAYBACK VOLUME ON AN ELECTRONIC DEVICE

摘要

Method of dynamically adapting playback volume on electronic device starts with processor receiving first user input and first portion of audio content. First user input signals to device to increase or decrease volume of sound output. Processor determines first loudness metric corresponding to first portion of audio content when first user input is received. First loudness metric is measure of loudness of first portion of audio content being outputted. Processor then stores in memory first loudness metric in association with first user input. Memory stores history of loudness metrics in association with user inputs. Processor then determines second loudness metric that is measure of loudness of second portion of audio content that is received and determines second user input associated with second loudness metric using history. Processor generates control signal to automatically control volume of sound output by device corresponding to second user input. Other embodiments are also described.

1. A method comprising:
receiving by a processor a first user input and a first portion of an audio content, wherein the first user input signals to an electronic device to increase or to decrease a volume of a sound output; determining by the processor a first loudness metric corresponding to the first portion of the audio content when the first user input is received, the first loudness metric being a measure of the loudness of the first portion of the audio content being outputted by the electronic device, wherein determining the first loudness metric includes reading the first loudness metric included in a metadata associated with the first portion of the audio content; storing by the processor in a memory the first loudness metric in association with the first user input, wherein the memory stores a history of loudness metrics in association with user inputs; determining by the processor a second loudness metric that is a measure of the loudness of a second portion of the audio content that is received, wherein determining the second loudness metric includes reading the second loudness metric included in a metadata associated with the second portion of the audio content; determining a second user input associated with the second loudness metric using the history; and generating by the processor a control signal to automatically control the volume of the sound output by the electronic device corresponding to a second user input.
