Description

Technical Field

[0001] The present invention relates to the technical field of audio data processing, and particularly to an audio data mixing method, a terminal and a computer-readable storage medium. Background Art

[0002] Voice mixing is an important part of multimedia conferences. Since the audio sources for mixing come from different devices and pass through different transmission paths, there is a delay between the moment when the audio data collected from each channel actually reaches the mixing module and the moment when the sound in the real world is generated. There may be significant differences in the delays between each channel. Especially for audio data transmitted over a network, due to additional processes such as encoding, network transmission, and decoding compared to analog audio acquisition, its delay will be significantly higher than that of analog audio sources. There may also be different delay performances between different audio acquisition devices due to internal processing procedures and network fluctuations. If the delay differences of each channel of audio are not processed and directly sent to the mixing module, the mixed audio data may have an overlapping sound problem, seriously affecting the mixing effect.

[0025] Please refer to Figure 1 , Figure 1 which is a schematic flowchart of the audio data mixing method provided by the present invention. In this embodiment, an audio data mixing method is provided. This method can be applied to the recording and broadcasting products in the education industry, and can also be applied to industries such as conference recording and broadcasting products. The audio data mixing method includes the following steps.

[0026] S11: Obtain the same audio information transmitted by at least two audio channels, where the audio information includes a standard synchronization sound source.

[0027] Specifically, a standard synchronous sound source played by a recording and playing host is collected through at least two audio channels, and the audio channels that collect the standard synchronous sound source transmit audio data to a mixing module in the recording and playing host. Among them, the transmission methods for the audio channels to transmit audio data to the mixing module in the recording and playing host include wired transmission, Bluetooth transmission, WIFI transmission, Zigbee transmission, etc. Since different audio data can transmit the collected standard synchronous sound source to the mixing module in the recording and playing host through different transmission methods, the transmission speeds of different transmission methods are different, and during the transmission process of the standard synchronous sound source, the encoding and decoding methods for the standard synchronous sound source are also different, resulting in a delay in the time when different audio channels transmit to the mixing module, and making it impossible for different audio channels to synchronously transmit the collected standard synchronous sound source to the mixing module.

[0028] S12: Determine the delay duration of the audio channel according to the time when the standard synchronous sound sources respectively transmitted by at least two audio channels are received.

[0029] Specifically, identify the audio information transmitted by the audio channel to determine the time when the standard synchronous sound source is received; according to the time when the standard synchronous sound source is received, determine the delay duration of the audio channel. In a specific embodiment, cache audio samples for a preset duration; convert the audio samples into an audio spectrum; determine whether the similarity between the audio spectrum and a preset spectrum of the standard synchronous sound source exceeds a preset similarity; if the similarity between the audio spectrum and the preset spectrum exceeds the preset similarity, then determine that the audio sample is the standard synchronous sound source; determine the time when the audio sample is received as the time when the standard synchronous sound source is received. Among them, the audio samples are converted into an audio spectrum through fast Fourier transform. In an alternative embodiment, obtain the audio sample points in the audio information; determine whether the amplitude of the audio sample points exceeds a threshold; if the amplitude of the audio sample points exceeds the threshold, then start caching the audio samples.

[0030] In a specific embodiment, the moment when the standard synchronous sound source is sent is the first time; the moment when the standard synchronous sound source transmitted by the audio channel is received is the second time; the difference between the second time and the first time is the delay duration of the audio channel.

[0031] In a specific embodiment, determine whether the number of times the standard synchronous sound source is played exceeds a preset number of times; if the number of times the standard synchronous sound source is played exceeds the preset number of times, then determine the average delay duration of the audio channel according to the multiple delay durations obtained for the audio channel.

[0032] S13: According to the delay durations corresponding to at least two audio channels, respectively determine the cache lengths of the queues respectively corresponding to at least two audio channels.

[0033] Specifically, select the maximum delay duration among the delay durations corresponding to at least two audio channels; calculate the differences between the other delay durations and the maximum delay duration among the delay durations corresponding to at least two audio channels respectively, so as to determine the buffer lengths of the queues corresponding to each audio channel respectively.

[0034] This embodiment provides an audio data mixing method. By obtaining the same audio information transmitted by at least two audio channels respectively, the audio information includes a standard synchronization sound source; according to the time of receiving the standard synchronization sound sources transmitted by at least two audio channels respectively, determine the delay duration of the audio channels; according to the delay durations corresponding to at least two audio channels, determine the buffer lengths of the queues corresponding to at least two audio channels respectively. This application detects the delay times of different audio channels, and determines the buffer lengths of the queues corresponding to other audio channels respectively based on the delay durations of all audio channels, so that the mixing module can receive the audio data transmitted synchronously by different audio channels, thereby improving the mixing effect.

[0035] Please refer to Figure 2 , Figure 2 FIG. is a schematic flowchart of a specific embodiment of the audio data mixing method provided by the present invention. In this embodiment, an audio data mixing method is provided. This method can be applied to the recording and broadcasting products in the education industry, and can also be applied to industries such as conference recording and broadcasting products. The audio data mixing method includes the following steps.

[0036] S201: At least two audio channels simultaneously collect the same standard synchronization sound source.

[0037] Specifically, the recording and broadcasting host emits a standard synchronization sound source, and records the time when the recording and broadcasting host emits the standard synchronization sound source as T0. The standard synchronization sound source emitted by the recording and broadcasting host is simultaneously collected through at least two audio channels. Among them, the number of audio channels can be two or more. Among them, the audio channels can be pickups, analog high-definition cameras, network cameras (IP Cameras, IPCs) and / or network dome cameras, or other audio acquisition devices, which are not limited here. The standard synchronization sound source is a beep with a fixed frequency and a fixed length, or other audio data. When the recording and broadcasting host emits the standard synchronization sound source, it is necessary to keep the environment quiet and play the standard synchronization sound source at a relatively high volume, so as to facilitate the subsequent recognition of the collected audio information.

[0038] S202: Obtain the audio sample points in the audio information.

[0039] Specifically, when the recording and broadcasting host receives the audio information sent by the audio channel, it obtains the audio sample points in the audio information in real time.

[0040] S203: Determine whether the amplitude of the audio sample point exceeds the threshold.

[0041] Specifically, first screen the audio information to filter out the audio before the standard synchronization sound source, thereby reducing the workload of converting audio samples into audio spectra subsequently. By comparing the audio sample points in the acquired audio information with a threshold value, it is then determined whether the audio sample points exceed the threshold value. Among them, the threshold value is determined according to the amplitude of the standard synchronization sound source to distinguish the standard synchronization sound source from noise.

[0042] If the audio sample points in the audio information exceed the threshold value, directly jump to step S204; if the audio sample points in the audio information do not exceed the threshold value, directly jump to step S202.

[0043] S204: Start caching audio samples.

[0044] If the amplitude of the audio sample points exceeds the threshold value, start caching audio samples. Specifically, the recording and playing host receives the audio information transmitted through the audio channel, and the recording and playing host caches the audio samples of a preset duration in real time. Among them, the audio samples can at least include part of the standard synchronization sound source.

[0045] S205: Convert the audio samples into audio spectra.

[0046] Specifically, in order to facilitate the comparison of the acquired audio samples with the standard synchronization sound source and more conveniently identify the audio samples, the audio samples are converted into audio spectra through fast Fourier transform.

[0047] S206: Determine whether the similarity between the audio spectrum and the preset spectrum of the standard synchronization sound source exceeds the preset similarity.

[0048] Specifically, compare the audio spectrum converted from the audio samples with the preset spectrum of the standard synchronization sound source, and then determine whether the acquired audio samples are the standard synchronization sound source or whether the acquired audio samples include the standard synchronization sound source. In a specific embodiment, by comparing whether the laws presented by the amplitudes at the frequency points of the audio spectrum converted from the audio samples and the amplitudes at the frequency points of the preset spectrum of the standard synchronization sound source are the same. It is also possible to perform the comparison through other mathematical methods, which are not limited here as long as the comparison between the audio spectrum and the preset spectrum can be achieved.

[0049] If the similarity between the audio spectrum and the preset spectrum of the standard synchronization sound source exceeds the preset similarity, directly jump to step S207; if the similarity between the audio spectrum and the preset spectrum of the standard synchronization sound source does not exceed the preset similarity, directly jump to step S202.

[0050] S207: Determine that the audio sample is the standard synchronization sound source; and determine the time when the audio sample is received as the time when the standard synchronization sound source is received.

[0051] Specifically, if the similarity between the audio spectrum and the preset spectrum of the standard synchronous sound source exceeds the preset similarity, it indicates that the audio sample is the standard synchronous sound source; and the reception time of the received audio sample is determined as the time T1 when the standard synchronous sound source is received, and then the time when the standard synchronous sound source collected by the audio channel is transmitted to the mixing module is obtained.

[0052] S208: Determine the delay duration of the audio channel according to the time when the standard synchronous sound source is sent by the received audio channel.

[0053] Specifically, the moment when the recording and playback host sends the standard synchronous sound source is the first time, recorded as T0; the moment when the standard synchronous sound source is received is the second time, recorded as T1; the delay duration DT of the audio channel is determined according to the difference between the second time and the first time, that is, DT = T1 - T0.

[0054] S209: Determine whether the number of times of playing the standard synchronous sound source exceeds the preset number of times.

[0055] Specifically, in order to improve the detection accuracy of the delay duration when the audio channel transmits audio information, the standard synchronous sound source needs to be sent by the recording and playback host multiple times, that is, repeat the above steps S201 to S208, and multiple delay durations need to be obtained for the same audio channel. And accumulate the number of times of repeating the above steps, and determine whether the number of times of repeating the above steps exceeds the preset number of times.

[0056] If the number of times of repeating the above steps exceeds the preset number of times, directly jump to step S210; if the number of times of repeating the above steps does not exceed the preset number of times, directly jump to step S201.

[0057] S210: Determine the average delay duration of the audio channel according to the multiple delay durations obtained by the audio channel.

[0058] Specifically, in order to improve the stability of the delay duration of the audio channel transmitting audio information, if the number of times of sending the standard synchronous sound source exceeds the preset number of times, the average delay duration of the audio channel is determined according to the multiple delay durations obtained by the audio channel. That is, calculate the average delay duration of the multiple delay durations corresponding to the same audio channel.

[0059] At this time, the average delay durations corresponding to different audio channels are obtained.

[0060] S211: Select the maximum delay duration among the delay durations corresponding to at least two audio channels.

[0061] Specifically, the average delay duration corresponding to different audio channels is obtained through the above steps. The average delay durations corresponding to different audio channels are sorted from largest to smallest, and the largest average delay duration is selected as the maximum delay duration corresponding to multiple audio channels. For example, the sorting of the maximum delay durations of each audio channel is as follows: DavgT0 (channel 0), DavgT1 (channel 1), …, DavgT n (channel n), and the maximum channel delay time among them is taken: DT max = Max{DavgT0, DavgT1, …, DavgT n} and the corresponding audio channel number is recorded as m.

[0062] S212: Calculate the differences between the other delay durations except the maximum delay duration and the maximum delay duration among the delay durations corresponding to at least two audio channels respectively, so as to determine the buffer lengths of the queues corresponding to each audio channel.

[0063] Specifically, adjust the buffer lengths of the queues corresponding to the other audio channels according to the maximum delay duration. That is, the delay durations of the other audio channels need to be kept consistent with the delay duration of audio channel m. Calculate the differences T i = DT max - DavgT i , where i is the audio channel number. Among them, the buffer length of the queue represents the time length of the audio samples that need to be buffered in the audio channel. In this embodiment, the audio samples can be blank data, that is, empty audio data.

[0064] According to the difference between the delay duration corresponding to the audio channel and the maximum delay duration and the sampling rate of obtaining the audio information, determine the buffer length L i of the queue of the audio channel, that is, L i = T i * F. Among them, L i is the number of audio sample points that need to be buffered, L i takes a positive integer, i is the audio channel number, and F is the sampling rate of the audio channel for obtaining audio information.

[0065] This embodiment provides an audio data mixing method, which acquires the same audio information transmitted by at least two audio channels respectively, and the audio information includes a standard synchronization sound source; determines the delay duration of the audio channels according to the time of receiving the standard synchronization sound sources transmitted by at least two audio channels respectively; and determines the buffer lengths of the queues corresponding to at least two audio channels respectively according to the delay durations corresponding to at least two audio channels. By detecting the delay times of different audio channels and determining the buffer lengths of the queues corresponding to other audio channels based on the delay durations of all audio channels, this application enables the mixing module to receive audio data synchronously transmitted by different audio channels, thereby improving the mixing effect.
