Embodiment Construction

[0049] Reference will now be made in detail to the embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are given in order to provide a thorough understanding of various described embodiments. It will be apparent, however, to one skilled in the art that various described embodiments may be practiced without these specific details. In other instances, well-known methods, procedures, components, circuits, and networks have not been described in detail so as not to unnecessarily obscure aspects of the embodiments.

[0050] An electronic device integrating a microphone and a speaker is configured to receive and output sound. The sound output by these devices may actually be affected by their placement in the listening room. For example, depending on the number of nearby reflective surfaces in the listening room (eg, nearby furniture, walls, or ceilings), bass frequencies of sounds output by ...

Abstract

The various implementations described herein include methods, devices, and systems for automatic audio equalization, in one aspect, a method is performed at a computing system that includes speaker(s), microphones, processors and memory. The computing system outputs audio user content and automatically equalizes the audio output of the computing system. The equalizing includes; (1) receiving the outputted audio content at each microphone of the plurality of microphones; (2) based on the received audio content, determining an acoustic transfer function for the room; (3) based on the determinedacoustic transfer function, obtaining a frequency response for the room; and (4) adjusting one or more properties of the speakers based on the determined frequency response.

Description

technical field [0001] The present invention relates generally to audio equalization, including but not limited to methods and systems for automatic audio equalization that do not require user action. Background technique [0002] Electronic devices integrating microphones and speakers have been widely used to collect voice input from users and output sounds (eg, music and speech). The quality of audio output can be affected by factors such as room environment and speaker placement in the room. Manual audio equalization is a process used to adjust the gain (response) of different frequencies of the audio output, usually to improve the quality of the output sound. However, manual equalization is a tedious and time-consuming task for the user. Also, it requires a lot of knowledge about speakers, microphones, and rooms, which is too advanced for the average user. [0003] Therefore, there is a need for a user to be able to experience high-quality audio without requiring the ...
