Detailed ways

The technical solution of the present invention will be described in further detail below through specific embodiments and accompanying drawings.

FIG. 1 is a schematic flowchart of an embodiment of a method for implementing a metronome function on a mobile terminal provided by the present invention. As shown in FIG. 1 , the execution subject of each step in the following method embodiments may specifically be various existing mobile terminal devices, such as mobile phones, personal computers, PADs, and the like. The method may specifically include:

S101, receiving a user's parameter setting instruction through the main thread, the parameter setting instruction carries beat, beat frequency and cycle number, and the cycle number is equal to the number of bars included in the beat.

Specifically, in this embodiment, the main thread controls each sound sub-thread to play audio files. In practical applications, users can set parameters such as beat, beat frequency, and cycle times through the buttons and touch screen of the mobile terminal, and generate parameter setting instructions, and can also preset audio files corresponding to each beat. The beat can be set to 1/4 beat, 2/4 beat, etc., the beat frequency can be set to 60 beats/min, 120 beats/min, etc. If the beat includes n bars, the number of cycles can be set to n times.

S102, receive the user's startup instruction through the main thread, and read the corresponding audio file according to the beat, and sequentially control at least two sound sub-threads to play the audio file according to the beat, beat frequency and cycle times, and the number of sound sub-threads is based on each beat in the beat. The number of beats for a measure is determined.

Wherein, when the beat number of each bar in the beat is equal to 1, the number of sound sub-threads is two; when the beat number of each bar in the beat is greater than 1, the number of sound sub-threads is the same as the beat number of each bar in the beat.

Specifically, in order to avoid the mutual influence of playing audio files between beats, the switching of playing audio files between beats can be realized by switching different sound sub-threads.

The following takes the beat as 1/4 beat, the beat frequency as 60 beats per minute, and the number of cycles as n times (that is, the number of measures is n) as an example to illustrate the specific process of this step:

Read the audio file corresponding to 1/4 beat, and each measure in 1/4 beat includes 1 beat, so only two sound sub-threads (the first sound sub-thread and the second sound sub-thread) are required. In the first section, you can control the first sound sub-thread to play the read audio file when it is 1 second away from the initial time, and then enter the second section, you can control the second sound sub-thread to play the read audio file when it is 2 seconds away from the initial time After entering the third section, the first sound sub-thread can be controlled to play the read audio file at 3 seconds from the initial time, and this loop continues until the playback of the nth section audio file is completed.

The following takes the beat as 2/4, the beat frequency as 60 beats/min, and the number of cycles as n times (that is, the number of measures is n) as an example to illustrate the specific process of this step:

Read the audio file corresponding to the 2/4 beat, and each measure in the 2/4 beat includes 2 beats, so only two sound sub-threads (the third sound sub-thread and the fourth sound sub-thread) are required. In the first section, you can control the third sound sub-thread to play the read audio file at 1 second from the initial time, control the fourth sound sub-thread to play the read audio file at 2 seconds from the initial time, and then enter the first In the second section, you can control the third sound sub-thread to play the read audio file when it is 3 seconds away from the initial time, and control the fourth sound sub-thread to play the read audio file when it is 4 seconds away from the initial time, and then enter the third section. The loop goes on like this until the playback of the nth bar audio file is completed.
