Based on the hardware structure of the mobile terminal 100 and the communication network system, various embodiments of the method of the present invention are provided.
Referring to fig. 3, fig. 3 is a flowchart illustrating steps of an audio playing method according to an embodiment of the present invention, where the method is applied to a mobile terminal, and as shown in fig. 3, the method includes:
In the step, the method detects the noise value of the environment where the mobile terminal is located, and can detect the noise value of the environment where the mobile terminal is located through a detection device arranged on the mobile terminal, and can also detect the noise value of the environment where the mobile terminal is located through an earphone connected to the mobile terminal. The method can detect the noise value of the environment where the mobile terminal is located at intervals of preset time, can also detect the noise value of the environment where the mobile terminal is located when the mobile terminal meets the preset trigger condition, and can also detect the noise value of the environment where the mobile terminal is located at intervals of preset time after the mobile terminal meets the preset trigger condition. The preset trigger condition may be that the mobile terminal is in an audio playing state, or that the mobile terminal is connected to an earphone and is in an audio playing state. The noise value may be a decibel value of noise.
The method can detect the noise value of the environment where the mobile terminal is located through a noise meter, and the noise meter can be arranged on the mobile terminal and can also be arranged on an earphone accessed to the mobile terminal. The frequency weighting network in the noise meter has A, B, C three standard weighting networks, the A network simulates the response of human ear to 40 square pure tones in equal loudness curve, and the curve shape of the noise meter is opposite to that of 340 square equal loudness curve, so that the middle and low frequency bands of the electric signal have larger attenuation. The B network simulates the response of the human ear to a pure 70 square tone, and it attenuates the low frequency band of the electrical signal to some extent. The C-network simulates the response of the human ear to a pure 100 square tone, with a nearly flat response over the entire audio frequency range. The sound pressure level measured by the noise meter through the frequency weighting network is called sound level, and according to the weighting network, the sound level is called A sound level, B sound level and C sound level, and the units are denoted as dB (A), dB (B) and dB (C). Noise meters can be classified by accuracy into precision noise meters and ordinary noise meters. The measurement error of the precision noise meter is about +/-1 dB, and the measurement error of the common sound level meter is about +/-3 dB. In the embodiment of the present invention, a precise noise meter may be adopted, and a general noise meter may also be adopted, which is not specifically limited in the present invention.
In this step, the method judges whether the audio file of the mobile terminal includes a target audio clip with a playing decibel value smaller than the noise value, if the audio file of the mobile terminal includes the target audio clip with the playing decibel value smaller than the noise value, execute step 303; on the contrary, if the audio file of the mobile terminal does not include the target audio clip with the playing decibel value smaller than the noise value, the process ends.
The target audio file of the mobile terminal may be an audio file currently played by the mobile terminal, or may be a next audio file of the audio file currently played by the mobile terminal. That is, the mobile terminal may determine whether the audio file currently played by the mobile terminal includes the target audio clip with the playback decibel value less than the noise value, or may determine whether the next audio file of the audio file currently played by the mobile terminal includes the target audio clip with the playback decibel value less than the noise value. The method for judging whether the target audio file of the mobile terminal comprises the target audio clip with the playing decibel value smaller than the noise value can specifically judge whether the target audio clip with the playing decibel value smaller than the noise value exists when the audio file is played at the current volume of the mobile terminal.
The method for judging whether the audio file of the mobile terminal comprises the target audio clip with the playing decibel value smaller than the noise value can also specifically judge whether the audio file comprises the clip with the sound straight line weakened by analyzing the frequency spectrum of the audio file according to the frequency spectrum of the audio file. The specific way of performing the spectrum analysis on the audio file may be to perform eight-frequency division sampling on the audio file, and perform FFT (Fast Fourier transform) algorithm processing on the audio data obtained by the sampling.
The principle is as follows: if the audio file is sampled at a sampling rate of 44.1K (44.1K points per second), some default output samples of the mobile terminal are also 44.1K (i.e. even if the high-quality audio downloaded by the mobile terminal is actually played, the bottom layer of the mobile terminal has been resampled, the audio file is compressed, and is not true high-quality audio). The audio data obtained by sampling is processed by an FFT (Fast Fourier transform) algorithm, the obtained new data is linearly stepped, the intervals of all the points are the same, and even if the audio frequency of the minimum standard 44.1K is subjected to frequency spectrum drawing, a plurality of low-frequency-band points cannot be obtained, so that the sampling rate needs to be reduced, 8 frequency division can be understood as reducing the sampling rate by 8 times, therefore, the frequency density after FFT operation can be increased by 1024 data, and the intervals can also be reduced, so that the low-frequency band needing to be displayed can be smoothly obtained. In the embodiment of the invention, the data can be drawn by taking 1K data as a unit, and the interval is 20 HZ-20 KHZ (standard).
The audio file may be music or video, and when the audio file is music, the target audio segment may be a blank in the beginning or end of the music.
In the step, when the audio file of the mobile terminal comprises the target audio segment which cannot cover the noise value, the method skips the target audio segment. The skipping of the target audio clip is specifically that the target audio clip is not played when the target audio file is played, so that the method can automatically skip the target audio clip which cannot cover the current environmental noise value in the audio file, effectively filter the environmental noise and avoid the interference of the environmental noise to users.
In the embodiment, the audio playing method detects the noise value of the environment where the mobile terminal is located; judging whether a target audio clip which cannot cover a noise value exists in an audio file of the mobile terminal; and if the target audio file of the mobile terminal comprises the audio clip with the playing decibel value smaller than the noise value, skipping the target audio clip. Therefore, the audio playing method provided by the invention can automatically skip the audio segments of the audio files which can not cover the noise of the environment where the mobile terminal is located, so that the audio files played by the mobile terminal can cover the noise of the environment where the mobile terminal is located, the environmental noise is effectively filtered, and the environmental noise is prevented from influencing users.
Optionally, the detecting a noise value of an environment in which the mobile terminal is located includes:
and if the mobile terminal is accessed to the earphone and is in an audio playing state, detecting the noise value of the environment where the mobile terminal is located.
In the embodiment, the method detects the noise value of the environment where the mobile terminal is located when the mobile terminal is accessed to the earphone and is in the audio playing state.
Optionally, the target audio clip is not played when the target audio clip is skipped to play the target audio file.
Optionally, the determining whether the target audio file of the mobile terminal includes a target audio clip with a playback decibel less than the noise value includes:
and judging whether the target audio file of the mobile terminal comprises a target audio clip of which the playing decibel value is less than the noise value when the target audio file is played at the current volume of the mobile terminal.
Optionally, the target audio file is an audio file currently played by the mobile terminal or a next audio file of the audio file currently played by the mobile terminal.
Referring to fig. 4, fig. 4 is a schematic flowchart of another audio playing method according to an embodiment of the present invention, and as shown in fig. 4, the method includes:
This step 401 is the same as step 301 in the embodiment shown in fig. 3, and is not described here again.
In this step, the method judges whether the noise value is greater than the preset noise value, if the noise value is greater than the preset noise value, execute step 403; on the contrary, if the noise value is not greater than the preset noise value, the process ends or the process returns to step 401, and the method continues to detect the noise value of the environment where the mobile station is located. The embodiment shown in fig. 4 is exemplified by the end of the process, but not limited thereto.
The preset noise value can be set by the user according to the actual condition (such as the maximum noise value that the user can accept) of the user, or can be a default noise value set by combining the conditions of most users.
And step 403, judging whether the target audio file of the mobile terminal comprises a target audio clip with a playing decibel value smaller than the noise value.
In this step, if the detected noise value is greater than the preset noise value, the method determines whether the target audio file of the mobile terminal includes a target audio segment whose playing decibel value is less than the noise value, and if the audio file of the mobile terminal includes the target audio segment whose playing decibel value is less than the noise value, executes step 404; on the contrary, if the audio file of the mobile terminal does not include the target audio clip with the playing decibel value smaller than the noise value, the process is ended.
The manner of determining whether the target audio file of the mobile terminal includes the target audio clip with the playback decibel value less than the noise value is described in detail in step 302 in the embodiment shown in fig. 3 of the present invention, and is not described herein again.
This step 404 is the same as step 303 in the embodiment of fig. 3 of the present invention, and is not described here again.
Referring to fig. 5, fig. 5 is a schematic flowchart of another audio playing method according to an embodiment of the present invention, and as shown in fig. 5, the method includes:
In this step, the method judges whether the noise value of the environment where the mobile terminal is located is greater than the preset noise value, if the noise value of the environment where the mobile terminal is located is greater than the preset noise value, the step 503 is executed; on the contrary, if the noise value of the environment where the mobile terminal is located is less than or equal to the preset noise value, the process is ended.
In this step, the method judges whether the target audio file of the mobile terminal includes a target audio clip with a playback decibel value less than the noise value, and if the target audio file of the mobile terminal includes a target audio clip with a playback decibel value less than the noise value, executes step 504; on the contrary, if the target audio file of the mobile terminal does not include the target audio clip with the playing decibel value smaller than the noise value, the process is ended.
And step 504, judging whether the duration of the target audio clip is greater than the preset duration.
In the step, when the target audio file of the mobile terminal comprises the target audio clip which can not cover the noise value, the method judges whether the time length of the target audio clip is greater than the preset time length. If the duration of the target audio segment is less than or equal to the preset duration, executing step 505; conversely, if the duration of the target audio segment is greater than the predetermined duration, go to step 506. The preset time length may be a default time length or a time length set by a user.
And step 505, skipping the target audio segment.
In this step, if the duration of the target audio segment is less than or equal to the preset duration, the method directly skips the target audio segment.
And step 506, skipping the audio segments with preset time length in the target audio segment.
In this step, if the duration of the target audio segment is greater than the preset duration, the method skips the segment with the preset duration in the target audio segment. In this way, it is possible to avoid skipping longer segments in an audio file, thereby avoiding affecting the user experience. The audio segment with the preset duration in the target audio segment may be any segment with the preset duration in the target audio segment, for example, the audio segment with the preset duration from the beginning to the preset duration in the target audio segment, the audio segment with the preset duration before the end in the target audio segment, or the audio segment with the preset duration in the middle of the target audio segment. For example, assuming that the duration of the target audio segment is 10 seconds and the preset duration is 5 seconds, the method may skip the audio segments of the target audio segment from 1 to 5 seconds, may also skip the audio segments of the target audio segment from 6 to 10 seconds, and may also skip the audio segments of the target audio segment from 4 to 8 seconds or the audio segments from 3 to 7 seconds.
In this embodiment, the target audio file may include a plurality of target audio segments having playback decibels smaller than the noise value, and the method determines whether each target audio segment is longer than a preset duration, and processes each target audio segment based on a determination result of each target audio file. For example, assuming that the preset time duration is 30 seconds, the segment playback decibel value between the 1 st second and the 10 th second in a song is less than the noise value, and the segment playback decibel value between the 50 th second and the 100 th second in a song is less than the noise value, the method may skip the segment between the 1 st second and the 10 th second in the song, and skip the segment between the 50 th second and the 80 th second in the song.
Optionally, skipping an audio segment of a preset duration in the target audio segment includes:
skipping the audio segments starting to the preset time length in the target audio segment.
In the embodiment, the audio playing method detects the noise value of the environment where the mobile terminal is located; judging whether the noise value is larger than a preset noise value or not; if the noise value is larger than the preset noise value, judging whether a target audio file of the mobile terminal comprises a target audio clip with a playing decibel value smaller than the noise value; if the audio file of the mobile terminal comprises an audio clip with a playing decibel value smaller than the noise value, judging whether the time length of the target audio clip is larger than a preset time length; if the duration of the target audio clip is less than or equal to the preset duration, skipping the target audio clip; and if the duration of the target audio clip is greater than the preset duration, the audio clip with the preset duration in the target audio clip. Therefore, the audio playing method provided by the invention can automatically skip the audio segments of the audio files which can not cover the noise of the environment where the mobile terminal is located, so that the audio files played by the mobile terminal can cover the noise of the environment where the mobile terminal is located, the environmental noise is effectively filtered, and the environmental noise is prevented from influencing users.
