[0024] In order to make the objectives, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0025] It should be clear that the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the embodiments of the present application.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. The singular forms of "a", "said" and "the" used in the present application and the appended claims are also intended to include the majority form, unless the context clearly indicates other meanings. The words "if" / "if" used herein can be interpreted as "at the time of" or "when" or "in response to determination".

[0027] In addition, in the description of this application, unless otherwise specified, "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0028] The audio signal processing method of the embodiment of the present application can be applied to mobile recording and broadcasting scenarios. In one application scenario of the present application: in an evening party, the recording and broadcasting host obtains the audio signal of the host or performer, but does not pick up the ambient sound, resulting in that when the recording and broadcasting host broadcasts the audio signal externally, the people watching the broadcast cannot experience the atmosphere of the evening party, which reduces the quality of the broadcast audio signal.

[0029] Based on this, the present application proposes an audio signal processing method, system, storage medium and electronic device.

[0030] See also Figure 1 The audio signal processing method provided in the embodiment of the present application comprises the following steps:

[0031] S10: Acquire a speech audio signal and an ambient audio signal.

[0032] The voice audio signal may be a sound signal of a user speaking, for example, an audio signal of a host or performer speaking at a party.

[0033] The ambient audio signal may be a sound signal in the surrounding environment, such as the applause of the audience and background music in a party.

[0034] In the embodiments of this application, please refer to Figure 2 , the user's voice audio signal and the ambient audio signal of the current environment of the recording and broadcasting host 100 can be collected through the sound pickup device 200. The user's voice audio signal can also be collected through the sound pickup device and the ambient audio signal of the current environment of the recording and broadcasting host can be collected through the microphone built into the recording and broadcasting host. Among them, the sound pickup device includes but is not limited to a microphone, a video camera or a camera with a sound pickup function.

[0035] S20: Determine an application scenario; and determine a corresponding audio processing method according to the application scenario.

[0036] The application scenarios include but are not limited to multimedia playback scenarios and recording scenarios. Specifically, in the multimedia playback scenario, the ambient sound needs to be presented. In the recording scenario, the ambient sound needs to be removed.

[0037] The audio processing method includes but is not limited to a speech enhancement method and a speech noise reduction method. Specifically, the speech enhancement method refers to enhancing the speech audio signal, and the speech noise reduction method refers to reducing the ambient sound noise of the speech audio signal.

[0038] In an embodiment of the present application, a user can manually input an application scenario on the recording and broadcasting host, or manually touch an operation to trigger the application scenario, or issue a voice control instruction, which triggers the application scenario after being received by the recording and broadcasting host. After determining the application scenario, the audio processing method corresponding to the triggered application scenario can be determined based on the mapping relationship between the preset application scenario and the audio processing method. Among them, in the mapping relationship between the preset application scenario and the audio processing method, one application scenario corresponds to a unique audio processing method. Specifically, the multimedia playback scenario corresponds to the voice enhancement method, and the recording scenario corresponds to the voice noise reduction method.

[0039] S30: Performing audio processing on the voice audio signal and the ambient audio signal according to the audio processing method.

[0040] In the embodiments of the present application, the voice audio signal may be enhanced, the ambient audio signal may be enhanced, the ambient sound of the voice audio signal may be eliminated or weakened, or the voice audio signal and the ambient audio signal may be mixed.

[0041] During an evening party, the recording and broadcasting host picks up the ambient sound and presents it in the external broadcast of the recording and broadcasting host. People watching the broadcast can feel the atmosphere of the evening party and have an immersive experience. At the same time, the recording host can also reduce the ambient noise of the host or performer's voice and audio signal, reduce the interference of the ambient sound on the host or performer's voice, and achieve the recording of high-quality voice and audio signals.

[0042] By using the embodiments of the present application, a voice audio signal and an ambient audio signal are obtained; an application scenario is determined; a corresponding audio processing method is determined according to the application scenario; and audio processing is performed on the voice audio signal and the ambient audio signal according to the audio processing method. The embodiments of the present application perform different audio processing on the voice audio signal and the ambient audio signal for different application scenarios, thereby presenting ambient sound, using ambient sound to enhance the atmosphere, and improving the quality of the audio signal.

[0043] In an alternative embodiment, see Figure 3 , step S10, including step S101, is as follows:

[0044] S101: Acquire a voice audio signal collected by a first sound pickup device and an ambient audio signal of a current environment collected by a second sound pickup device; wherein the second sound pickup device is located at a plurality of preset positions in the current environment.

[0045] In an embodiment of the present application, the first sound pickup device 210 can be a handheld microphone, a head-mounted microphone, or a lavalier microphone of the host or performer. The first sound pickup device 210 is connected to the recording and broadcasting host 100 via a wired or wireless connection to collect the speaking voice of the host or performer and send the collected voice audio signal to the recording and broadcasting host 100.

[0046] The second sound pickup device 220 can be a wireless microphone, a video camera or a camera with a sound pickup function. The second sound pickup device 220 is connected to the recording and broadcasting host 100 by wire or wireless connection, and is used to collect the ambient audio signal of the environment where the recording and broadcasting host 100 is located, and send the collected ambient audio signal to the recording and broadcasting host 100. Among them, the second sound pickup device 220 can be set at several preset positions of the current environment to collect ambient sounds at different positions of the current environment. Through the first sound pickup device 210 and the second sound pickup device 220, voice audio signals and ambient audio signals can be automatically and quickly obtained.

[0047] In an alternative embodiment, see Figure 4 , step S10, including steps S111 to S112, are as follows:

[0048] S111: Sending the same clock signal to the first sound pickup device and the second sound pickup device respectively, so that the clock signal of the first sound pickup device is synchronized with the clock signal of the second sound pickup device.

[0049] In the embodiment of the present application, the Network Time Protocol (NTP) is used to synchronize the clock signals of the first sound pickup device and the second sound pickup device. Specifically, the clocks of the first sound pickup device and the second sound pickup device are synchronized with the clock of the recording and broadcasting host by using the recording and broadcasting host as the clock source and the first sound pickup device and the second sound pickup device as the receiving end.

[0050] S112: Acquire a voice audio signal collected by a first sound pickup device and a first collection time when the voice audio signal is collected, and acquire an ambient audio signal collected by a second sound pickup device and a second collection time when the ambient audio signal is collected.

[0051] In the embodiment of the present application, when the voice audio signal is collected by the first sound pickup device, the first sound pickup device marks the collection time of the voice audio signal to obtain the first collection time. When the ambient audio signal is collected by the second sound pickup device, the second sound pickup device marks the collection time of the ambient audio signal to obtain the second collection time. The first sound pickup device sends the voice audio signal and the corresponding first collection time to the recording and broadcasting host, and the second sound pickup device sends the ambient audio signal and the corresponding second collection time to the recording and broadcasting host.

[0052] Since the voice audio signal and the ambient audio signal may be lost, repeated or unable to be processed during the transmission to the recording and broadcasting host, by synchronizing the clock signal and obtaining the first acquisition time and the second acquisition time, it can be ensured that the voice audio signal and the ambient audio signal can be transmitted and processed in the correct order.

[0053] In an optional embodiment, the step of determining the application scenario in step S20 includes step S201, which is specifically as follows:

[0054] S201: In response to a trigger request of an application scenario, determine an application scenario identifier from the trigger request; wherein the application scenario identifier corresponds to a unique application scenario.

[0055] The application scenario identifier may be letters, numbers or symbols.

[0056] In an embodiment of the present application, the user interface of the recording and broadcasting host displays an application scenario list, which includes several application scenarios. The user can trigger any application scenario in the application list. The recording and broadcasting host detects the user's trigger operation, generates a trigger request, parses the trigger request, obtains an application scenario identifier, and determines the application scenario based on the application scenario identifier.

[0057] According to the trigger request of the application scenario, the application scenario can be determined automatically and quickly.

[0058] In an optional embodiment, the step of determining a corresponding audio processing method according to an application scenario includes:

[0059] S211: If the application scenario is a multimedia playback scenario, determine that the audio processing method is a speech enhancement method.

[0060] In the embodiment of the present application, in the mapping relationship between the preset application scenarios and the audio processing methods, the audio processing method corresponding to the multimedia playback scenario is the speech enhancement method.

[0061] According to the audio processing method, the steps of performing audio processing on the voice audio signal and the ambient audio signal include:

[0062] S301: In a speech enhancement mode, a speech audio signal is enhanced to obtain a first audio signal; and an ambient audio signal is suppressed to obtain a second audio signal.

[0063] In the embodiment of the present application, the voice audio signal can be enhanced by increasing the volume, or by using a voice enhancement method. The voice enhancement method includes but is not limited to a voice enhancement algorithm based on spectral subtraction, a voice enhancement algorithm based on Kalman filtering, and a voice enhancement method based on a neural network. The ambient audio signal can be suppressed by reducing the volume, or by using an inverse sound wave superposition method.

[0064] S302: Mix the first audio signal and the second audio signal to obtain a mixed audio signal.

[0065] In the embodiment of the present application, waveform superposition and amplitude limiting operations are performed on the first audio signal and the second audio signal to obtain a mixed audio signal.

[0066] By enhancing the voice audio signal and suppressing the ambient audio signal, the voice audio signal in the mixed audio signal will not be masked by the ambient audio signal. At the same time, the ambient sound can also be presented to create an atmosphere.

[0067] In an optional embodiment, the step of determining a corresponding audio processing method according to an application scenario includes:

[0068] S221: If the application scenario is a recording scenario, determine that the audio processing method is a speech noise reduction method.

[0069] In the embodiment of the present application, in the mapping relationship between the preset application scenario and the audio processing method, the audio processing method corresponding to the recording scenario is the speech noise reduction method.

[0070] According to the audio processing method, the steps of performing audio processing on the voice audio signal and the ambient audio signal include:

[0071] S311: extracting ambient audio features of ambient audio signals in a speech noise reduction mode.

[0072] The ambient audio features include but are not limited to the time domain features, frequency domain features and Mel spectrum of the ambient sound.

[0073] In an embodiment of the present application, the time domain features of the ambient audio signal are extracted, wherein the time domain features of the ambient audio signal include the audio amplitude of the ambient sound.

[0074] S312: Perform environmental sound noise reduction on the speech audio signal according to the environmental audio characteristics to obtain a noise-reduced speech audio signal.

[0075] In the embodiment of the present application, the time domain features of the speech audio signal are extracted. The time domain features of the speech audio signal include the audio amplitude of the speaking sound. The time domain features of the audio signal are subtracted from the time domain features of the ambient audio signal to obtain the denoised speech audio signal.

[0076] By extracting the ambient audio features of the ambient audio signal, the ambient sound in the speech audio signal can be automatically and quickly removed, thereby improving the quality of the speech audio signal.
