It is to be understood that the specific embodiments described herein are for purposes of illustration and not limitation. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a flowchart of a volume adjusting method according to an embodiment of the present invention, where this embodiment is applicable to a situation where a terminal device automatically adjusts playing volume when playing sound source data, and the method may be executed by the terminal device according to the embodiment of the present invention, and a volume adjusting device of the terminal device may be implemented in a software and/or hardware manner, as shown in fig. 1, a specific scheme provided in this embodiment is as follows:
step S101, when detecting that the terminal equipment plays the sound source, obtaining the volume information of the sound source and the volume currently used by the terminal equipment.
In one embodiment, the terminal device may play the sound source through an installed third-party application or audio/video playing software carried by the system. The method mainly comprises the steps of obtaining, decoding, outputting and the like of the sound source file. Illustratively, the obtained sound source file may be a multicast stream received through a network, or may be an audio/video file locally stored by the terminal device; loading the sound source file into a memory buffer area after the sound source file is obtained; the method comprises the steps of decoding a sound source file loaded into a memory buffer area, before decoding starts, if the sound source file simultaneously contains video data, separating the audio data from the video data, and inputting the separated audio data into an audio decoder, wherein the audio decoder is mainly used for reading the audio data in the memory buffer area to obtain a digital audio signal and converting the digital audio signal into an analog audio signal, and a playing device of a terminal device plays audio according to the analog audio signal. In one embodiment, when it is monitored that a sound source playing event is triggered, it is determined that the terminal device starts playing a sound source, where the triggering event may be that a playing button displayed in a touch screen is pressed, or that a playing device of the terminal device, such as a speaker, starts playing sound, and the terminal device is determined to play the sound source.
And when detecting that the terminal equipment plays the sound source, acquiring the volume information of the sound source. In one embodiment, the digital audio signal decoded by the audio decoder may be sampled to determine the volume information corresponding to the sound source. In another embodiment, an original file of a currently played sound source may also be obtained, and volume information corresponding to the sound source may be determined through parsing the original file. In another embodiment, for example, in an Android system, the volume information of the sound source may be obtained through an Android.
The volume currently used by the terminal device may be a set volume of a system in the terminal device, and the volume may be changed according to the adjustment of the volume (e.g., volume key) of the terminal device by the user. Specifically, taking the android system as an example, the current volume of the terminal device may be determined by a getVolume method of the AudioManager.
And step S102, determining the gain of the sound source according to the volume information.
Gain refers to the degree of increase (amplification factor) in decibels of current, voltage, or power in a component, circuit, device, or system. Optionally, the gain of the analog audio signal to be output may be adjusted by controlling the gain amplifier. The gain adjustment is performed by determining the gain, for example, the gain determined by the volume information may be an adjustment gain used by the terminal equipment system when playing the sound source, or may be a gain recorded in the volume information corresponding to the sound source when playing.
And step S103, judging whether the gain and the volume meet preset adjusting conditions, if so, executing step S104, and if not, executing step S105.
In one embodiment, the gain and the volume level satisfying the preset adjustment condition include: the gain is smaller than a preset gain threshold, and the volume is smaller than a preset volume threshold. The terminal equipment is divided into 18 adjustable grades from mute to maximum volume, each grade corresponds to a volume value, and different volume values represent different volume sizes of a terminal equipment system. Illustratively, the preset volume threshold may be 3, 4, or 5, etc. The preset gain threshold may be any value between greater than 1 and less than 2, such as 1.2. In this embodiment, when it is determined that the gain of the sound source is smaller than the preset gain threshold and the volume of the terminal device is smaller than the preset volume threshold, step S101 is executed to perform volume adjustment, otherwise step S105 is executed to end the control of volume adjustment.
And step S104, adjusting the volume information of the sound source.
In one embodiment, the adjusting the volume information of the sound source includes: and adjusting the gain of the sound source according to a preset adjusting algorithm. For example, the preset adjustment algorithm may perform overall gain adjustment on the amplitude of the sound source, and if the gain adjustment coefficient is set to 1.5, the sound source performs gain according to the gain adjustment coefficient of 1.5 when playing. In another embodiment, it may also be that, first, a corresponding sound source amplitude is determined according to the sound source information, where the amplitude refers to the maximum distance from the original position during the vibration of the object, the loudness of the sound heard by the human ear is related to the amplitude of the sound source, and the loudness is stronger when the amplitude is larger. In an embodiment, the audio information decoded by the audio decoder may be sampled to obtain amplitude information within a preset time period T, where the amplitude information may be composed of a plurality of amplitude values, an amplitude curve of a sound source played within the preset time period T may be correspondingly determined according to the obtained plurality of amplitude values, and different gain coefficients may be set according to different magnitudes of the amplitude curve, and for example, specific correspondence may be shown in the following table:
TABLE 1
| Amplitude of vibration | Gain factor |
| Greater than-3 db or less than-50 db | 1 |
| Less than-10 db and greater than-50 db | 2 |
| Less than-3 db and greater than-10 db | 1.5 |
As shown in Table 1, when the amplitude of the source is greater than-3 db or less than-50 db, its gain is not adjusted; when the amplitude is less than-10 db and greater than-50 db, the amplitude is a high amplitude region to which a gain coefficient of 1.5 is assigned, and when the amplitude is less than-10 db and greater than-50 db, the amplitude is a medium amplitude region to which an amplitude coefficient of 2 is assigned to significantly increase the amplitude of the portion of the amplitude.
And step S105, ending.
According to the volume adjusting method, when the gain of the sound source is too small or is 0db gain, and the current volume of the terminal equipment is low, the volume information of the sound source is adjusted, the amplitude of the sound source can be changed in a gain adjusting mode to improve the volume of the sound source, the automatic adjustment of the volume of the sound source is achieved to meet the adjustment requirement of a user on the volume, and the volume adjusting efficiency is improved.
In a possible embodiment, after adjusting the gain of the sound source according to a preset adjustment algorithm, the method further includes: and when the terminal equipment plays the audio signal after the gain adjustment, if a sound breaking signal is detected, reducing the gain of the audio signal and/or reducing the current volume of the terminal equipment. For example, an audio signal with a detected amplitude greater than a certain set amplitude (e.g., 3db) may be determined as a sound break signal, and when the sound break signal is detected, the current volume of the terminal device is reduced or the gain is reduced accordingly to avoid the sound break.
Fig. 2 is a flowchart of another volume adjustment method according to an embodiment of the present invention, where on the basis of the foregoing embodiment, optionally, after adjusting the gain of the sound source according to a preset adjustment algorithm, the method further includes: and carrying out noise filtering on the audio signal obtained after the adjustment according to a noise suppression algorithm. As shown in fig. 2:
step S201, when detecting that the terminal equipment plays the sound source, obtaining the volume information of the sound source and the volume currently used by the terminal equipment.
Step S202, determining the gain of the sound source according to the volume information.
Step S203, determining whether the gain is smaller than a preset gain threshold, and the volume is smaller than a preset volume threshold, if yes, performing step S204, and if no, performing step S205.
And S204, adjusting the gain of the sound source according to a preset adjusting algorithm, and filtering the noise of the audio signal obtained after adjustment according to a noise suppression algorithm. Illustratively, a noise suppression method of Wiener filter, an LMS filter noise suppression algorithm, or the like may be employed.
And step S205 is ended.
As can be seen from the above discussion, in the process of adjusting the sound volume information of the sound source satisfying the condition, the noise amplified by the gain is suppressed and eliminated, and the problem that the noise is amplified and affects the sound quality is avoided.
Fig. 3 is a flowchart of another volume adjustment method according to an embodiment of the present invention, and optionally, before adjusting the gain of the sound source according to a preset adjustment algorithm, the method further includes: determining a corresponding noise amplitude value according to the volume information; and filtering the noise amplitude value larger than the preset noise amplitude. As shown in fig. 3:
step S301, when detecting that the terminal equipment plays the sound source, acquiring the volume information of the sound source and the volume currently used by the terminal equipment.
Step S302, determining the gain of the sound source according to the volume information.
Step S303, determining whether the gain is smaller than a preset gain threshold, and the volume is smaller than a preset volume threshold, if yes, performing step S304, and if no, performing step S306.
Step S304, determining a corresponding noise amplitude value according to the volume information, and filtering the noise amplitude value larger than a preset noise amplitude.
In one embodiment, the identification process of the noise may be to identify the amplitude and frequency in the volume information, and if it is detected that the amplitude and frequency in the volume information segment satisfy a randomness condition, that is, the amplitude and frequency are not regular, the noise may be identified, or, according to the amplitude curve of the audio information, the part with too small amplitude may be identified as the noise. When the amplitude curve of the noise is determined, the noise amplitude value larger than the preset noise amplitude (such as-30 db to-50 db) is filtered correspondingly to avoid the noise from being amplified by the gain.
And S305, adjusting the gain of the sound source according to a preset adjusting algorithm.
And S306, ending.
As can be seen from the above discussion, before the volume information of the sound source is adjusted by changing the gain, the noise reduction process is performed to prevent the sound quality of the sound source from being affected by the noise after the noise is significantly increased, thereby further improving the effect of volume adjustment.
Fig. 4 is a flowchart of another volume adjustment method according to an embodiment of the present invention, and optionally, after adjusting the gain of the audio source, the method further includes: and adjusting the volume of the terminal equipment. Wherein, the adjusting the volume of the terminal device comprises: determining the gain of the sound source gain adjustment, and determining corresponding volume adjustment information according to the gain; and adjusting the volume of the terminal equipment according to the volume adjusting information. As shown in fig. 4, the steps are as follows:
step S401, when detecting that the terminal equipment plays the sound source, acquiring the volume information of the sound source and the volume currently used by the terminal equipment.
Step S402, determining the gain of the sound source according to the volume information.
Step S403, determining whether the gain is smaller than a preset gain threshold, and the volume is smaller than a preset volume threshold, if yes, performing step S404, and if no, performing step S406.
Step S404, determining the gain of the sound source gain adjustment according to a preset adjustment algorithm.
Step S405, determining corresponding volume adjustment information according to the gain, and adjusting the volume of the terminal equipment according to the volume adjustment information.
In one embodiment, the corresponding volume adjustment information is determined based on the gain level. Illustratively, the larger the gain, the larger the current playing volume of the terminal device is increased. In a possible embodiment, a specific way of adjusting the volume is given, and optionally, the current volume value of the terminal device is adjusted by setting a target volume value. Illustratively, the terminal device is divided into 18 adjustable levels from mute to maximum volume, each level corresponds to a volume value, and the target volume value can be any one of 14-18 levels, depending on the specific gain. In a possible embodiment, the volume of the terminal device may be adjusted by using a volume change value, which may be 3,5,8, etc., that is, the volume change value is increased based on the current volume to increase the current system volume of the terminal device.
And step S406, ending.
From the above discussion, it can be known that, when the sound source satisfies the volume adjustment condition, the gain of the sound source is adjusted, and meanwhile, the current playing volume of the terminal device is also synchronously and adaptively adjusted, so that the volume adjustment effect is improved, and meanwhile, the problem that the final volume cannot be obviously improved due to the fact that the current system volume of the terminal device is too small and only the gain of the sound source is adjusted is avoided.
