Problems solved by technology

[0002] At present, the audio processing method based on the Android system is used in application scenarios such as singing and tape recorders. After the audio input is recorded, the audio playback is performed. The time delay between audio playback and audio input exceeds 120ms or even longer. When singing or recording with the above method, you will obviously experience the long audio playback delay mentioned above, and the user experience is poor

Abstract

The invention discloses an audio playback method based on an Android system and electronic equipment. The audio playback method comprises the following steps: setting an audio playback mode control module; determining and transmitting an audio information transmission path; determining and outputting an audio information output path; and when the control state of the audio playback mode is 1, allowing an audio output driving module to respectively receive first audio information of an audio input driving module and second audio information of an audio output intermediate module, taking third audio information formed by operation of the first audio information and the second audio information as input information, and outputting the input information. By arranging the audio playback mode control module, the audio information playback transmission path is shortened, audio playback delay is shortened, and user experience is improved.

Description

technical field [0001] The present application relates to the field of audio processing, and more specifically, relates to an audio playback method based on an Android system. Background technique [0002] At present, the audio processing method based on the Android system is used in application scenarios such as singing and tape recorders. After the audio input is recorded, the audio playback is performed. The time delay between audio playback and audio input exceeds 120ms or even longer. When singing or recording in the above-mentioned method, the above-mentioned longer audio playback delay will be obviously experienced, and the user experience is poor. [0003] Therefore, there is a need for an improved audio playback method. Contents of the invention [0004] The object of the present invention is to provide an audio playback method based on the Android system to reduce audio playback delay and improve user experience in view of the defects and deficiencies in the abo...
