Problems solved by technology

[0003] When the terminal develops audio, it usually needs to integrate a third-party audio processing module. During the tuning stage of audio parameters, audio playback, recording, and FM listening, various pop sounds, noises, and current sounds often appear, which are difficult to analyze and locate. These stages of noise bring great difficulties to audio development
In addition, different types of audio have different processing methods for audio output channels. When playing different types of audio sources, it is impossible to switch to an effective audio output channel in real time and accurately, which will introduce obvious current noise.
For example, when music is playing in the background, and then preview the ringtone in the settings, after the ringtone is played for a few seconds, there will be different degrees of noise

Embodiment 1

[0066] The first embodiment of the present invention provides a method for adaptively switching audio effect output channels. The method is applied to audio effect processing of a terminal, and the terminal includes an audio effect output channel adaptive switching module 307. Specifically, please refer to image 3 , Is the overall frame diagram of the audio output channel. in image 3 In, based on the Android (Android) operating system, it involves the Android application layer, the Android native framework layer, the kernel layer, and the digital signal processing layer. An audio source player application 301 and a media player 302 run on the Android application layer. In the Android local framework layer, there are media playback service 303, Android multimedia playback framework 304, audio track 305, audio mixer 306, audio output channel adaptive switching module 307, audio hardware abstraction layer 308, Bluetooth hardware abstraction layer 309, and Bluetooth Protocol sta...

example 1

[0081] Step 1: The current sound effect output channel of the mobile terminal is the speaker output channel. When the earphone is plugged into the headphone jack, an instruction to switch the sound effect output channel is triggered.

[0082] Step 2: Query the headphone output channel on the sound effect chain.

[0083] Step 3: Remove the speaker output channel from the sound effect chain.

[0084] Step 4: Obtain the headphone output channel.

[0085] Step 5: Switch from the speaker output channel to the headphone output channel.

[0086] Step 6: Detect the audio source data, and play the audio source data through the earphone output channel.

example 2

[0088] Step 1: The current sound effect output channel of the mobile terminal is the prompt sound output channel. When ringtone data is detected, an instruction to switch the sound effect output channel is triggered.

[0089] Step 2: Query the ringtone output channel on the sound effect chain.

[0090] Step 3: Remove the prompt sound output channel from the sound effect chain.

[0091] Step 4: Obtain the ringtone output channel.

[0092] Step 5: Switch from the prompt sound output channel to the ringtone output channel.

[0093] Step 6: Play the ringtone data with the ringtone output channel.

[0094] More specifically, please refer to Figure 5 , Before step 440, further includes the steps:

[0095] Step 510: Close the audio port of the first sound effect output channel.

[0096] Step 520: Update the second audio effect output channel to the audio port of the current audio output channel.

Abstract

The present invention discloses a method of adaptively switching sound effect output channels and a terminal, and belongs to the terminal technology field. The method is applied to the sound effect processing of the terminal, the terminal comprises a sound effect output channel adaptive switching module, and the method of adaptively switching the sound effect output channels by the sound effect output channel adaptive switching module comprises the steps of removing a first sound effect output channel which is a current sound effect output channel; obtaining a to-be-switched second sound effect output channel; switching the sound effect output channel from the first sound effect output channel to the second sound effect output channel; playing the sound source data via the second sound effect output channel. According to the method of adaptively switching the sound effect output channels and the terminal of the present invention, the purpose sound effect output channel can be switched to real-timely and accurately, the sound effect real-time response processing is guaranteed, and the tone tuning efficiency and the auditory experience of the terminal are improved.

Description

Technical field [0001] The present invention relates to the technical field of terminals, and in particular to a method and terminal for adaptively switching sound effect output channels. Background technique [0002] In the mobile Internet era, with the promotion and popularization of smart terminals, the demand for terminal audio playback sound quality and sound effects is getting higher and higher. High bitrate, multi-channel, and lossless audio sources have gradually become standard. Users need enhanced stereo sound, Realism. [0003] When the terminal develops audio, it is usually necessary to integrate a third-party sound processing module. During the sound parameter tuning stage, audio playback, recording, and FM listening, various pop sounds, noises, and current sounds often appear, which are difficult to analyze and locate These noise phases bring greater difficulties to audio development. In addition, different types of audio have different sound effect output channel p...
