The following clearly describes the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure.
A recording method and a recording play method provided in the embodiments of the present disclosure may be applied to a system architecture shown in
During technical implementation of the embodiments of the present disclosure, a sound source positioning technology and a directional play technology are used. Accordingly, three microphones are used as an example in the embodiments of the present disclosure, and brief descriptions are as follows.
Sound source positioning technology: It takes time to transmit a sound in the air, a combination of the three microphones is used to calculate differences between time at which a sound reaches the three microphones and a relative location of the microphone combination such that an azimuth of a sound source relative to a plane on which the microphones are located can be learned, and positioning of a sound source direction is implemented.
Directional play technology: Recording is performed using a combination of the three microphones, and each microphone may record an audio, three audio inputs may be combined to reduce noise, a sound in a specified direction is picked, and a sound in another direction is suppressed in order to improve a signal-to-noise ratio of the sound in the specified direction such that the sound in the specified direction can be highlighted, and a directional play function is implemented.
In the embodiments of the present disclosure, the microphone array may include at least three microphones. Multiple sounds may be recorded using combinations of different microphones. For ease of description, a processing process of sound recording is referred to as recording in the following in the embodiments of the present disclosure. In
The recording method and the recording play method provided in the embodiments of the present disclosure may be applied to a mobile terminal. A recording apparatus for implementing a recording function and a recording play apparatus for implementing a recording play function may be used as a part of the mobile terminal or may exist independently. It may be understood that the mobile terminal in the embodiments of the present disclosure may be a terminal that has recording and recording play functions, such as a smartphone.
The recording method in the embodiments of the present disclosure is described in detail below.
In an embodiment of the present disclosure, refer to
Step S101. Obtain recording data in all sound source directions.
Further, in this embodiment of the present disclosure, the recording apparatus may collect sounds in all the sound source directions using a microphone array. The microphone array includes at least three microphones, and sound source directions in 360° azimuths relative to a plane on which the microphones are located may be collected using the at least three microphones. Therefore, if all the 360° azimuths relative to the plane on which the microphones are located have sound sources that make sounds, all the sound source directions may be understood as all sound source directions that make sounds and that are in the 360° azimuths relative to the plane on which the microphones are located.
Step S102. Generate a recording file, where the recording file saves the recording data in all the sound source directions.
In this embodiment of the present disclosure, the recording apparatus may save, as the recording file in a storage location corresponding to an application for implementing a recording function, all the recording data that is in all the sound source directions and that is collected by the microphone array, that is, generate the recording file that can implement a recording play function.
In this embodiment of the present disclosure, the recording apparatus saves all the recording data in all the sound source directions in the recording file such that the complete recording data is retained. When recording is played subsequently, sounds in all the sound source directions can be played, and a recording play direction can be adjusted according to a direction that is set by a user.
In a process in which the user uses the recording apparatus to perform recording, it is inevitable that sounds in multiple sound source directions exist at a same time point, but the user may focus on only a specific sound source direction. For example, in a conference process, discussion is heated in the conference, but the user focuses on a speech of only a key role. Optionally, in this embodiment of the present disclosure, the user may set a sound source direction in which a sound that needs to be recorded is located, and set the specified sound source direction in which the sound that needs to be recorded is located as a recording direction. The recording apparatus obtains the recording direction that is set by the user and saves the recording direction in the recording file such that when the recording file is played, playing can be performed according to the specified recording direction.
Refer to
Step S201a. Obtain recording data in all sound source directions input by at least three microphones.
Step S201b. Obtain a recording direction that is set by a user.
In this embodiment of the present disclosure, the recording direction is one of at least two sound source directions, and the at least two sound source directions are obtained by the at least three microphones at a same time point. In other words, in this embodiment of the present disclosure, on the basis of recording the recording data in all the sound source directions, the recording apparatus may emphatically record, according to the recording direction that is set by the user, recording data corresponding to the specified recording direction.
Step S202. Save, in a recording file, all the recording data in all the sound source directions and the recording direction that is set by the user.
It should be noted that a recording process and sound source positioning are two different implementation processes. Therefore, in this embodiment of the present disclosure, an execution sequence of obtaining the recording direction that is set by the user and performing the steps of the recording process shown in
It should be understood that in this embodiment of the present disclosure, the recording data in all the sound source directions input by the at least three microphones is a set formed by recording data in sound source directions obtained by the at least three microphones at different time points, and there may be more than one sound source direction obtained by the at least three microphones at a same time point. In this embodiment of the present disclosure, the embodiment corresponding to the method shown in
Further, in this embodiment of the present disclosure, the recording direction that is set by the user is determined according to a sound source adjustment gesture input by the user, and the sound source adjustment gesture is used to adjust the recording direction. The recording method provided in this embodiment of the present disclosure may be applied to a mobile terminal having a touchscreen. Therefore, the user may input the specified recording direction using the touchscreen.
Further, in this embodiment of the present disclosure, a sound source direction mark may be displayed on a touchscreen display interface. The sound source direction mark is used to mark a sound source direction. For example, in this embodiment of the present disclosure, the sound source direction mark may be a pointer. The user adjusts the sound source direction mark to adjust the recording direction. Therefore, the recording apparatus may obtain, in the following manner, the recording direction that is set by the user, obtaining the sound source adjustment gesture input by the user. For example, the sound source adjustment gesture may be input using a gesture of touching and tapping, sliding, or the like by a finger on the touchscreen display interface, or may be input using an air gesture or the like. This is not limited in this embodiment of the present disclosure. In this embodiment of the present disclosure, if the user inputs the sound source adjustment gesture, the recording apparatus may determine, according to the sound source adjustment gesture, a display location of an adjusted sound source direction mark on the touchscreen display interface, and determine that a sound source direction indicated by the display location of the adjusted sound source direction mark on the touchscreen display interface is the recording direction that is set by the user.
During specific implementation, in this embodiment of the present disclosure, a pointer used to identify a sound source direction may be set and displayed on a display interface of the mobile terminal in a recording process in order to indicate a sound source direction. The user may adjust, on the touchscreen, the pointer used to identify a sound source direction. The recording apparatus obtains an adjustment track of the adjustment, by the user on the touchscreen, of the pointer used to identify a sound source direction, and determines that a location indicated by an end point of the adjustment track is the recording direction. For example, in a conference room, after the user starts a sound recorder application in the mobile terminal, a pointer used to identify a sound source direction may be displayed on a display interface that displays a sound recorder, and the pointer points to a direction in which a person makes a speech. Discussion is heated and many people speak in the conference, but the user may focus on only a key role that makes a speech. Therefore, a pointing direction of the pointer may be adjusted to a sound source direction in which the key role makes a speech, and the direction is set to the recording direction. The recording apparatus obtains the specified recording direction and saves the recording direction in the recording file such that when the recording file is played, playing can be performed according to the saved recording direction.
Further, in this embodiment of the present disclosure, the user may separately set different recording directions at different time, that is, the recording direction that is set by the user includes at least two different recording directions that are separately set by the user at different time such that the recording direction can be adjusted at any time according to the recording direction specified by the user in the recording process, and recording in a corresponding sound source direction can be implemented. For example, in a conference discussion process, the user may focus on speeches of different roles at different time, for example, focuses on a speech of a role A at time TA and focuses on a speech of a role B at time TB. Therefore, the user may set, at the time TA, the recording direction to a sound source direction in which the role A is located, input a sound source adjustment gesture at the time TB, and adjust the recording direction to a sound source direction in which the role B is located. The recording apparatus emphatically records, at the time TA, a sound in the sound source direction in which the role A is located, switches the recording direction after obtaining the sound source adjustment gesture of the user for adjusting the recording direction to the sound source direction in which the role B is located, and emphatically records, at the time TB, a sound in the sound source direction in which the role B is located.
A method implementation process in which a recording play apparatus plays recording based on a recording file obtained using the recording play method provided in the foregoing embodiment is described in detail in an embodiment of the present disclosure below.
Step S301. Obtain a recording file.
In this embodiment of the present disclosure, the recording file obtained by the recording play apparatus saves recording data in all sound source directions input by at least three microphones.
Step S302. Determine a recording play direction.
In this embodiment of the present disclosure, the recording play direction may be understood as a sound source direction specified by a user, and the specified sound source direction is at least one sound source direction of all the sound source directions input by the at least three microphones.
In this embodiment of the present disclosure, the user may adjust the recording play direction by inputting a play direction adjustment gesture, for example, set the recording play direction by inputting the play direction adjustment gesture on a touchscreen display interface.
In this embodiment of the present disclosure, a sound source direction mark may be displayed on the touchscreen display interface, and the user adjusts the sound source direction mark by inputting the play direction adjustment gesture in order to adjust the recording play direction. The recording play apparatus obtains a display location of an adjusted sound source direction mark on the touchscreen display interface, and determines that a sound source direction indicated by the display location of the adjusted sound source direction mark on the touchscreen display interface is the recording play direction that is set by the user. For example, in this embodiment of the present disclosure, the user may set the recording play direction by adjusting a pointer used to identify a sound source direction, and the recording play apparatus may determine the recording play direction by obtaining a direction to which the pointer points.
Step S303. The recording play apparatus determines, in the recording file according to the determined recording play direction, recording data that matches the recording play direction.
Step S304. Play the determined recording data.
In this embodiment of the present disclosure, the recording play apparatus may perform, according to the determined recording play direction and the determined recording data, noise reduction processing on an audio output signal corresponding to the recording data in the recording play direction in order to improve a signal-to-noise ratio of the audio output signal corresponding to the recording data in the recording play direction, and play recording corresponding to the recording data in the recording play direction.
The recording play direction may be set and adjusted by the user. Therefore, in the present disclosure, a direction-adjustable recording play function can be implemented. For example, the recording play direction includes a first recording play direction and a second recording play direction, and the first recording play direction and the second recording play direction are different recording play directions that are set by the user at different time points. For example, the user sets the first recording play direction at a time point T1, and inputs the play direction adjustment gesture at a time point T2. The play direction adjustment gesture is used to adjust the recording play direction. The recording play apparatus may play the determined recording data in the following manner of playing first recording data, where the first recording data is recording data that is determined in the recording file and that matches the first recording play direction, obtaining the play direction adjustment gesture input by the user, where the play direction adjustment gesture is used to adjust the recording play direction, and switching, according to the play direction adjustment gesture, from playing the first recording data to playing second recording data, where the second recording data is recording data that is determined in the recording file and that matches the second recording play direction.
Optionally, if the recording file saves a recording direction, the recording play direction may be determined according to a process of a method shown in
Step S3011. Determine whether a user sets a specified play direction.
In this embodiment of the present disclosure, the specified play direction is determined according to the play direction adjustment gesture input by the user, and the play direction adjustment gesture is used to adjust the recording play direction. For example, whether the user inputs the sound source adjustment gesture on the touchscreen display interface may be determined. If the user inputs the sound source adjustment gesture on the touchscreen display interface, it is determined that the user sets the specified play direction, or if the user does not input the sound source adjustment gesture on the touchscreen display interface, it is determined that the user does not set the specified play direction.
Further, in this embodiment of the present disclosure, in a process in which the recording play apparatus or a mobile terminal having a recording play function plays the recording file, a pointer used to identify a sound source direction may be displayed on the display interface. Therefore, whether the user sets the specified play direction may be determined by determining whether the user adjusts the pointer used to identify a sound source direction. If the user adjusts the pointer for identifying a sound source direction, it is determined that the user sets the specified play direction, or if the user does not adjust the pointer for identifying a sound source direction, it is determined that the user does not set the specified play direction.
In this embodiment of the present disclosure, if the user sets the specified play direction, step S3012 is performed, or if the user does not set the specified play direction, step S3013 is performed.
Step S3012. If the user sets the specified play direction, set the specified play direction as the recording play direction.
Step S3013. If the user does not set the specified play direction, set the recording direction as the recording play direction.
In this embodiment of the present disclosure, if the recording file saves the recording direction, the recording play apparatus may use the saved recording direction as a default recording play direction, and plays recording according to the default recording play direction if the user does not specify the play direction, or plays recording according to the play direction specified by the user if the user specifies the play direction.
