detailed description

The present application will be described below in conjunction with the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the application and are not intended to be limiting. For the convenience of description, only some but not all of the structures related to the present application are shown in the drawings. The features in the embodiments can be arbitrarily combined with each other without conflict.

Before discussing the exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as a process or method depicted as a flowchart. Although a flowchart depicts each operation (or step) as a sequential process, many of the operations can be implemented in parallel, concurrently, or concurrently. In addition, the order of each operation can be rearranged. The process may be terminated when each step operation is completed, but may also have additional steps not included in the figures. The processing may correspond to methods, functions, procedures, subroutines, subroutines, and the like.

Embodiment 1

1 is a flowchart of a channel data matching method according to Embodiment 1 of the present application. This embodiment is applicable to a case where a user plays a stereo music through a terminal configured with two speakers, and the method can be provided by the embodiment of the present application. The vocal tract data matching device is implemented, and the device can be integrated in a terminal, such as a mobile phone. As shown in FIG. 1, the method includes:

In S110, a current matching relationship between the first speaker and the second speaker and the left channel and the right channel is determined according to the terminal posture.

Most of the terminals sold in the market are equipped with two speakers, which are premised on the posture of the terminal when the user normally uses the terminal to make a call or send a short message, and the first speaker is usually set at the terminal. The second speaker is disposed at a lower side edge of the terminal; or the first speaker and the second speaker are juxtaposed at an upper edge or a lower edge of the terminal, optionally, the first A speaker may be disposed on the left side of the second speaker. For example, the first speaker is used to play the left channel data, and the second speaker is used to play the right channel data, thereby realizing the playback of the stereo music. However, when the first speaker used to play the left channel data is closer to the left ear than the user's right ear, the first speaker still plays the left channel data, and the second speaker that is closer to the right ear of the user's left ear remains The right channel data is also played, which will result in poor stereo music playback, which is unacceptable to some music lovers.

Therefore, in order to achieve better stereo music playing effect, optionally, the current matching relationship between the first speaker and the second speaker and the left channel and the right channel may be determined according to the current posture of the terminal. The terminal posture may refer to a relative positional relationship between two speakers configured on the terminal and the user, that is, which speaker is closer to the left ear of the user, and which speaker is closer to the right ear of the user.

In S120, the position of the left channel data and the right channel data in the current frame of the pulse code modulation PCM is adjusted according to the current matching relationship.

Wherein, the PCM data frame exists in a certain data format, and the data format identifies which data bits in the PCM data store left channel data, and which data bits store right channel data. When the current matching relationship between the first speaker and the second speaker and the left channel and the right channel is different from the default matching relationship at the initialization, the left channel data and the right channel in the current frame of the PCM are adjusted through the hardware abstraction layer. The location of the data. For example, the default matching relationship at initialization is that the left channel data is played by the first speaker, and the right channel data is played by the second speaker, when the current matching relationship between the first speaker and the second speaker and the left channel and the right channel is When the first speaker is closer to the right channel and the second speaker is closer to the left channel, the position of the left channel data and the right channel data in the current frame of the PCM is adjusted through the hardware abstraction layer.

Optionally, the foregoing step may be: if the location of the left channel data and the right channel data in the current frame of the PCM is different from the current matching relationship, extracting the left channel data in the current frame by using a hardware abstraction layer The right channel data is buffered, and the positions of the left channel data and the right channel data in the current frame are exchanged to form a new data frame and replace the current frame.

Because many third-party algorithms are loaded and run in the audio framework layer, for example, the third-party algorithm may be a control algorithm that controls the matching of the channel data of a specific speaker and a compensation algorithm for specific audio compensation of specific channel data. The audio data processed by the algorithm will be read through the speaker hardware layer and played by the corresponding speakers. However in the third-party algorithm Before the audio data is processed, the system does not know the current matching relationship between each speaker and each channel. Therefore, if the left and right channel data are exchanged in the speaker hardware layer, the number of the left and right speaker cavities will be seriously affected. The compensation effect of the three-party algorithm on the audio data, for example, optimizing the compensation sound effect algorithm for a speaker cavity modeling. Therefore, the position of the left channel data and the right channel data in the current frame of the pulse code modulation PCM can be adjusted by the hardware abstraction layer according to the current matching relationship before the third algorithm is loaded.

Optionally, before the location of the left channel data and the right channel data in the current frame of the PCM is adjusted according to the current matching relationship, the method may further include:

Processing audio data based on at least one algorithm to obtain the PCM data;

Optionally, the algorithm may be a Dolby sound algorithm or an audio fidelity Dirac algorithm.

When using the Dolby sound algorithm, the Dolby decoder can be used to obtain PCM data; when using the Dirac algorithm, the PCM data can be obtained by decoding with Nuplayer or AwesomePlayer.

Optionally, after the location of the left channel data and the right channel data in the current frame of the PCM is adjusted according to the current matching relationship, the method may further include:

The PCM data is processed based on at least one of the following algorithms: a Dolby sound algorithm, an audio fidelity Dirac algorithm. To enhance the playback of stereo music or to simultaneously play other sounds than the music sound.

In S130, the current frame is sent to the speaker hardware layer for the speaker hardware layer to read the audio data in the current frame and output to the first speaker and the second speaker for playback.

Wherein, the current frame is composed of left channel data and right channel data, and the left channel data can be controlled by the first speaker by loading a third party algorithm, the right channel data is played by the second speaker, or the left channel data is Two speakers are played, and the right channel data is played by the first speaker.

A channel data matching method provided by this embodiment determines the current matching relationship between the first speaker and the second speaker and the left channel and the right channel according to the terminal posture, and adjusts the pulse coding according to the current matching relationship. Modulating the position of the left channel data and the right channel data in the current frame of the PCM, and then transmitting the current frame to the speaker hardware layer for the speaker hardware layer to read the audio data in the current frame and outputting to the first The speaker and the second speaker are played to enhance the playback of stereo music.
