detailed description

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to FIG. 1, FIG. 1 is a schematic flowchart diagram of an embodiment of a playback processing method during audio switching according to the present invention. In this embodiment, the playback processing method during the audio switching includes:

Step S10, when playing audio on the local audio device, receiving audio data to be played sent by the external audio device;

In this embodiment, the local audio device and the external audio device are not limited. The local audio device specifically refers to the device that currently plays audio, and the external audio device refers to the device that transmits the audio file to the local audio device. For example, the local audio device can be a smart TV, a smart phone, etc., and the external audio device can be a smart phone, a smart TV, or the like. The external audio device can transmit the audio data to be played to the local audio device by wireless or wired.

Step S20, performing gain attenuation processing on the gain value of the corresponding audio data in the local audio data according to the preset first audio processing rule;

Step S30, performing gain enhancement processing on the gain value of the corresponding audio data in the audio data to be played according to the preset second audio processing rule;

When the local audio playback is suddenly interrupted and the external audio playback is switched, if the current local audio playback sound volume is particularly high, such as the racing game sound; and the volume of the switched playback sound is very low, this will cause a sudden change in the audio sound. , causing a sound that interferes with howling, thereby making the user feel uncomfortable. Therefore, it is necessary to perform smooth transition processing on the playback at the time of audio switching to reduce the interference sound generated during the switching process.

In this embodiment, the smooth transition processing process of the audio switching is specifically set, and the local audio data after the gain attenuation processing is continuously outputted in the smooth transition processing process, and the gain value is also enhanced by the audio data to be played. . The gain value is the attribute value of the audio data, that is, the volume of the played volume. Based on the user experience, in the embodiment, it is preferable to perform attenuation processing of the gain value on the exited local audio data, and perform enhancement processing of the gain value on the entered audio data to be played. For the setting of the first audio processing rule, for example, the gain values of all the local audio data input during the smooth transition processing time may be uniformly attenuated by a fixed value; or the corresponding comparison of the audio data input during the smooth transition processing time may be performed. The high-gain value is subjected to the attenuation processing and the like, and the setting of the second audio processing rule is similar. In the embodiment, the first audio processing rule and the second audio processing rule are not limited, and may be specifically set according to actual needs. It should be noted that when the local audio data and the gain of the audio data to be played are processed correspondingly, it is necessary to consider not only the interference problem generated when the sudden switching is performed, but also the user having a good hearing experience. For example, it is slowly and slowly attenuated or slowly increased.

Step S40, outputting the local audio data subjected to the gain attenuation processing and the audio data to be played after performing the gain enhancement processing to the audio decoder on the local audio device according to a preset audio output rule. Decode playback on.

The smooth transition processing process of the audio switching includes not only the processing of the output content, but also the processing of the output mode, such as the output order of the local audio data and the audio data to be played, and the corresponding output duration, etc., in addition, due to the output content Pre-intervention processing has been carried out, so the output method also needs to be processed accordingly. In this embodiment, the setting of the audio output rule is not limited, and is specifically set according to actual needs.

In this embodiment, the execution order of the above steps S20 and S30 is not limited. In this embodiment, when the audio data sent by the external audio device is received to switch with the current local playing audio, interference noise is generated to avoid sudden switching, and the corresponding audio data in the received audio data to be played is performed. Gain enhancement processing, performing gain attenuation processing on the corresponding audio data in the local audio data, and after performing the audio switching, continuing to output the processed local audio data and outputting the processed audio data to be played for smoothing The transition processing, that is, corresponding to increasing the output volume of the audio data to be played and correspondingly reducing the output volume of the local audio data, thereby solving the noise interference generated when the audio is switched between the two different audio devices, and simultaneously playing the audio after switching. A smooth transition to enhance the user experience.

Referring to FIG. 2, FIG. 2 is a schematic diagram of the refinement process of step S20 in FIG. In this embodiment, the foregoing step S20 includes:

Step S201, acquiring, in a preset first duration, a plurality of first gain values that are greater than a preset first gain threshold among the gain values of the local audio data in the first duration;

Step S202, calculating an average value of the selected preset first number of first gain values as an attenuation value for performing the gain attenuation processing;

Step S203, performing attenuation processing of the first gain value according to the attenuation value.

In this embodiment, based on the user experience, the smooth transition process of the audio switching should not be too long, for example, 1 second, so the first duration can be set to 0.5-1 seconds, which is set according to actual conditions. In addition, in this embodiment, it is preferable to attenuate the relatively large gain value of the gain value of the local audio data, and not to process the relatively small gain value, thereby ensuring the user's auditory experience during local audio playback to some extent. Taking the audio data with 8 bits of sampling as an example, the maximum gain value is 255 and the minimum gain value is 0. Therefore, the intermediate gain value 127 (or 128) can be used as the distinguishing line of the larger gain value. A gain value greater than 127 over a period of time is set to a first gain value. In this embodiment, the setting of the first gain threshold is not limited, and is specifically set according to actual needs.

Further, for determining the attenuation value of the gain attenuation, in the embodiment, an average value of the randomly selected preset first number of first gain values is preferably used as the attenuation value for performing the gain attenuation processing. Wherein, the first number of settings is not limited, for example, five first gain values are randomly selected for calculation to obtain corresponding attenuation values. In this embodiment, since the gain values corresponding to different audio files are different, and the gain values of the same audio file may be different at different times, the attenuation value needs to be calculated and determined according to a preset calculation rule. In addition, since the attenuation value in the embodiment is only used as the playback process at the time of audio switching and the processing time is short, the user mainly cares about the influence of the interference noise during the audio switching, and is not very concerned about the sound effect during the processing. Therefore, in this embodiment, the average value of any number of the first gain values is preferably used as the attenuation value, and the average value of the first gain value is used to avoid the user's feeling that the switching of the audio is not natural enough because the attenuation value is set too large. It is also possible to avoid the delay in processing the delay due to the setting of the attenuation value being too small, thereby affecting the user experience.

Further, the attenuation processing of the first gain value is performed based on the calculated attenuation value. For example, if the first gain value is 250, 140, 190, 210, 170, ... in the order of play, the attenuation value is 192, and the corresponding attenuation values after the attenuation processing are 58, 0, 0, 18, 0 in order. .... It should be noted that since the gain value has a certain value range, that is, has a maximum value and a minimum value, when the attenuation process of the gain value is performed, the gain value after the processed gain value is less than or equal to the minimum value is recorded as the minimum value. value. For example, when the gain value is less than zero, it is recorded as zero.

This embodiment is a preferred embodiment of performing gain attenuation processing on the gain value of the corresponding audio data in the local audio data. Of course, the attenuation processing of the gain value of the local audio data is not limited to the above manner. For example, the first gain value is sequentially 250, 140, 190, 210, 170, ... in the order of playback, and the corresponding gain values after the attenuation processing are sequentially The values of 100, 90, 80, 70, 60, ..., that is, the gain values are sequentially attenuated by 150, 50, 110, 140, 110..., and the attenuation processing methods are different, and the corresponding audio output effects are also different. By attenuating the larger gain value in the first time period, the interference noise caused by the excessive volume during local audio switching is prevented, and the volume of the local audio can be smoothly attenuated during the smooth transition process of the audio switching. To improve the user experience.

Referring to FIG. 3, FIG. 3 is a schematic diagram of the refinement process of step S30 in FIG. In this embodiment, the foregoing step S30 includes:

In step S301, a second second gain value of the gain value of the to-be-played audio data in the second duration is less than a preset second gain threshold, in a preset second duration;

Step S302, calculating an average value of the selected preset second quantity of second gain values as an enhancement value for performing gain enhancement processing;

Step S303, performing enhancement processing of the second gain value according to the enhancement value.

In this embodiment, based on the user experience, the smooth transition process of the audio switching should not be too long, for example, 1 second, so the second duration can be set to 0.5-1 seconds, which is set according to the actual situation. In addition, in this embodiment, it is preferable to perform enhancement processing on a relatively smaller gain value of the local audio data, and to compare the larger gain value without processing, thereby ensuring the user's auditory experience during local audio playback to a certain extent. Taking the audio data with 8 bits of sampling as an example, the maximum gain value is 255 and the minimum gain value is 0. Therefore, the intermediate gain value 127 (or 128) can be used as the distinguishing line of the smaller gain value, that is, the first A gain value of less than 127 over a period of time is set to a second gain value. In this embodiment, the setting of the second gain threshold is not limited, and is specifically set according to actual needs.

Further, for determining the enhancement value of the gain enhancement, in the embodiment, an average value of the randomly selected preset second number of second gain values is preferably used as the enhancement value for performing the gain enhancement processing. The second number of settings is not limited. For example, five second gain values are randomly selected for calculation to obtain corresponding enhancement values. In this embodiment, since the gain values corresponding to different audio files are different, and the gain values of the same audio file may be different at different times, the enhancement value needs to be calculated and determined according to a preset calculation rule. In addition, since the enhancement value in the embodiment is only used as the playback process at the time of audio switching and the processing time is short, the user mainly cares about the influence of the interference noise during the audio switching, and is not very concerned about the sound effect during the processing. Therefore, in this embodiment, an average value of any number of second gain values is preferably used as an enhancement value, and an average value of the second gain values is used to avoid that the user feels that the switching of the audio is not natural enough due to the excessive setting of the enhancement value. It is also possible to avoid the delay in processing the delay due to the setting of the attenuation value being too small, thereby affecting the user experience.

Further, according to the calculated enhancement value, the attenuation processing of the second gain value is sequentially performed in the playback order of the audio data corresponding to the second gain value in the second duration. For example, if the second gain value is 50, 70, 30, 90, 100, ... in the order of play, the enhancement value is 68, and the corresponding enhanced gain values are 118, 138, 98, 158, 168, respectively. .... It should be noted that since the gain value has a certain value range, that is, has a maximum value and a minimum value, when the gain value is enhanced, the gain value after the processed gain value is greater than or equal to the maximum value is recorded as the maximum value. value. For example, if the gain value is greater than 255, it is recorded as 255.

This embodiment is a preferred embodiment of performing a gain enhancement process on the gain value of the corresponding audio data in the local audio data. Certainly, the attenuation processing of the gain value of the local audio data is not limited to the above manner. For example, the second gain value is sequentially 50, 70, 30, 90, 100, ... in the order of playback, and the corresponding gain values after the enhancement processing are sequentially For the 100, 110, 120, 130, 140..., that is, the gain value is sequentially enhanced by 50, 40, 90, 40, 40..., and the enhanced processing manner is different, and the corresponding audio output effects are also different. By enhancing the smaller gain value in the second duration, the interference noise caused by the volume being too small when the audio to be played is switched is prevented, and the volume of the audio to be played is smoothed during the smooth transition process of the audio switching. Enhance the rise and improve the user experience.

Referring to FIG. 4, FIG. 4 is a schematic diagram of the refinement process of step S40 in FIG. In this embodiment, the foregoing step S40 includes:

Step S401, the local audio data after the gain attenuation processing is output to the audio decoder on the local audio device for decoding and playing in the first duration after the start of the output of the local audio data;

Step S402, the audio data to be played after the gain enhancement processing is output to the audio decoder on the local audio device for decoding and playing in the second duration after the end of the output of the local audio data. .

In this embodiment, in order to avoid the occurrence of interference noise caused by sudden switching, the smoothing transition process of an audio switching is continued after the switching instruction is started to continue the output of the local audio, that is, the local audio data after the attenuation processing is output. In addition, based on the user's auditory experience, for example, the user is not particularly sensitive to the change of the sound within one second. Therefore, in this embodiment, the first time duration is 500 milliseconds, and the second time length is 500 milliseconds, and the local audio data is output. The local audio data after the attenuation processing is outputted within 0 to 500 milliseconds after the start, and the audio data to be played after the enhanced processing is outputted within 500 to 1000 milliseconds, and then the audio is smoothly processed during the smooth transition process of the audio switching. The gain is first attenuated and then enhanced, thereby solving the noise interference generated when the audio is switched between two different audio devices, and the audio playback can be smoothly transitioned during the audio switching process to enhance the user experience.

Referring to FIG. 5, FIG. 5 is a schematic flowchart diagram of another embodiment of a playback processing method during audio switching according to the present invention. In this embodiment, after the step S10, the method includes:

Step S50: Calculate a total data amount of the audio data to be played according to the received audio parameter of the to-be-played audio data.

Step S60: determining, according to the calculated total data amount of the audio data to be played, whether the total data amount of the audio data to be played is greater than a preset threshold data amount;

Step S70, if yes, determining that the received audio data to be played is interference data and stopping performing playback processing on the interference data.

In this embodiment, the audio data to be played can be decoded and played after being transmitted at one time, and can also be decoded and played while being transmitted, and is specifically set according to actual needs. Regardless of the transmission method used, the receiving end (that is, the local audio device) needs to allocate corresponding storage space to the received audio data.

For example, the relevant audio parameters of the received audio data to be played, such as the total duration of the audio, the number of channels, the sampling frequency, and the number of samples, can be according to the formula: storage capacity (bytes) = sampling frequency × sampling accuracy / 8 × channel number × time, the total amount of data of the audio data to be played is calculated. For example, the sampling frequency is 8KHZ, the sampling digit is 16 digits, the total audio duration is 2 minutes, and the total data volume of the corresponding audio is (8000*16*2*2*60)/(8*). 1024*1024)=3.66M, that is, it needs to allocate at least 3.66M of storage space.

Further, in order to eliminate the influence of the interference data, after calculating the total amount of data received, further determining whether the value is greater than a preset threshold data amount, for example, 1 KB, if it is greater than 1 KB, determining audio data; If it is less than or equal to 1 KB, it is judged to be abnormal audio data, that is, interference data, and if it is interference data, playback processing of audio switching is not required.
