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...
