As shown in fig. 1, the system architecture may include an audio playing terminal 101 and an audio effect testing terminal (the audio effect testing terminal may be a smart phone 102, a tablet 103, and a portable computer 104 as shown in fig. 1, but may also be a desktop computer, etc.). The audio playing terminal 101 and the audio effect testing terminal may be connected through a wired communication link or a wireless communication link, for example, the audio playing terminal 101 and the audio effect testing terminal may be connected through a data line.
It should be understood that the number of audio playback terminals 101 and audio effect test terminals shown in fig. 1 is merely illustrative. There may be any number of audio playback terminals 101 and audio effect test terminals, as desired for implementation.
In one embodiment of the present application, after the audio playing terminal 101 establishes a connection with the audio effect testing terminal, if an audio playing instruction is received, a designated audio source may be played based on the audio playing instruction, then audio data generated by the designated audio source during playing is obtained, and the audio data is transmitted to the audio effect testing terminal, so that the audio effect testing terminal may output the audio data, and extract acoustic information of the audio data for display. For example, the audio effect test terminal may extract level information, loudness information, and spectrum information of the audio data, and generate a presentation interface based on the extracted acoustic information to present the acoustic information.
In one embodiment of the present application, the audio playback terminal 101 may display a playback interface of an audio source, and may display information of an audio effect test terminal that establishes a connection on the playback interface. If the user selects the instruction for testing the audio output effect of the specified audio effect test terminal on the audio playing terminal 101, the audio playing terminal 101 may send a control instruction to the other audio effect test terminals or stop sending audio data to the other audio effect test terminals, so as to control the other audio effect test terminals to stop outputting audio data.

The following details of implementation of the technical solution of the embodiment of the present application are set forth in detail from the perspective of the audio playing terminal and the audio effect testing terminal, respectively:
fig. 2 shows a flowchart of a method of monitoring an audio output effect, which may be performed by the audio playback terminal 101 shown in fig. 1, according to an embodiment of the present application. Referring to fig. 2, the method for monitoring the audio output effect at least includes steps S210 to S240, which are described in detail as follows:
in step S210, a connection is established with the audio effect test terminal.
In one embodiment of the application, the audio playing terminal can be connected with the audio effect testing terminal through the data connecting wire, so that the lossless transmission of audio data can be realized, and the testing accuracy of the audio output effect can be conveniently realized. For example, as shown in fig. 3, the audio playing terminal 301 establishes a connection with the audio effect testing terminal 302 through the data connection line 303 to transmit audio data to the audio effect testing terminal 302 through the data connection line 303.
In one embodiment of the present application, if the wireless communication technology can achieve lossless audio data transmission, the audio playing terminal may also establish a connection with the audio effect testing terminal through the wireless communication technology, so as to ensure the accuracy of the audio output effect test.
In step S220, a specified audio source is played.
In one embodiment of the present application, playing the specified audio source may be playing the specified audio source in response to an audio playing instruction triggered by a user, or may be playing audio sources in other application software (such as various streaming media player clients).
In one embodiment of the present application, the audio playing terminal may display an audio source list and identification information corresponding to each audio source in the audio source list, where the identification information is used to identify whether the audio source can be selected for playing, and play at least one audio source in response to at least one audio source selected by a user in the audio source list. For example, as shown in fig. 3, the audio playing terminal may display an audio source list 304, and may display identification information 305 corresponding to each audio source in the audio source list, which may identify whether the audio source can be selected for playing, e.g., audio source 1 and audio source 3 are selected, indicating that audio source 1 and audio source 3 are selected for playing, and audio source 2 is not selected, indicating that audio source 2 is not playing, and if audio source 2 is selected, audio source 2 may be played.
In one embodiment of the application, as shown in FIG. 3, the audio source list 304 may be displayed along with information for each audio source in the audio source list.
With continued reference to fig. 2, in step S230, audio data generated by the specified audio source at the time of playback is acquired.
In step S240, the audio data is transmitted to the audio effect testing terminal, so that the audio effect testing terminal outputs the audio data, and extracts acoustic information of the audio data for display.
In one embodiment of the present application, after the audio playing terminal obtains the audio data generated by the designated audio source during playing, the audio data may be stored in the buffer area, and then the audio data may be taken out from the buffer area and transmitted to the audio effect testing terminal.
In one embodiment of the present application, a transmission delay of audio data may be obtained, and then a size of a buffer may be adjusted according to the transmission delay of the audio data, wherein the size of the buffer has a positive correlation with the transmission delay. That is, the larger the buffer, the greater the transmission delay of the audio data; the smaller the buffer, the smaller the transmission delay of the audio data, and thus if the transmission delay of the audio data is large, the size of the buffer can be reduced.
In one embodiment of the present application, a playing interface of the audio source may also be displayed, and information specifying the audio source and information of the audio effect test terminal that establishes the connection may be displayed on the playing interface. For example, as shown in fig. 3, a play interface of each audio source may be displayed and information 306 of the audio effect test terminal establishing the connection may be displayed.
In some embodiments of the present application, based on the foregoing solutions, in a case where a plurality of audio effect test terminals establish a connection, if an instruction to test an audio output effect of a specified audio effect test terminal of the plurality of audio effect test terminals is received, a control instruction is sent to other audio effect test terminals of the plurality of audio effect test terminals to control the other audio effect test terminals to stop outputting the audio data. For example, as shown in fig. 3, the identification information 307 may be displayed for each audio effect test terminal that establishes a connection, where the identification information 307 may be a check box, and if the check box is checked, it indicates that the audio output effect of the audio effect test terminal corresponding to the check box needs to be tested.
In some embodiments of the present application, based on the foregoing solutions, in a case where a plurality of audio effect test terminals establish a connection, if an instruction for testing an audio output effect of a specified audio effect test terminal of the plurality of audio effect test terminals is received, sending of audio data to other audio effect test terminals of the plurality of audio effect test terminals is stopped, and further, the other audio effect test terminals may also be controlled to stop outputting the audio data.
Fig. 4 illustrates a flowchart of a method of monitoring an audio output effect, which may be performed by the audio effect test terminal illustrated in fig. 1, according to an embodiment of the present application. Referring to fig. 4, the method for monitoring audio output effect at least includes steps S410 to S430, which are described in detail as follows:
in step S410, a connection is established with the audio playback terminal.
In one embodiment of the application, the audio effect test terminal can be connected with the audio playing terminal through the data connecting wire, so that the lossless transmission of audio data can be realized, and the test accuracy of the audio output effect can be conveniently realized. For example, as shown in fig. 3, the audio playing terminal 301 establishes a connection with the audio effect testing terminal 302 through the data connection line 303 to transmit audio data to the audio effect testing terminal 302 through the data connection line 303.
In one embodiment of the present application, if the wireless communication technology can achieve lossless audio data transmission, the audio effect test terminal may also establish a connection with the audio playing terminal through the wireless communication technology, so as to ensure the test accuracy of the audio output effect.
In step S420, audio data transmitted by the audio playing terminal is received, where the audio data is generated after the audio playing terminal plays the audio source.
In one embodiment of the present application, after receiving the audio data transmitted by the audio playing terminal, the audio effect testing terminal may store the audio data in a buffer, and may further extract the audio data from the buffer for output.
In one embodiment of the present application, an output delay of audio data may be obtained and then a buffer size may be adjusted according to the output delay of the audio data, wherein the buffer size is in positive correlation with the output delay. That is, the larger the buffer, the greater the output delay of the audio data; the smaller the buffer, the smaller the output delay of the audio data, and thus if the output delay of the audio data is large, the size of the buffer can be reduced.
With continued reference to fig. 4, in step S430, the audio data is output, and acoustic information of the audio data is extracted for presentation.
In one embodiment of the present application, the step S430 of extracting acoustic information of audio data for presentation includes: extracting at least one of the following acoustic information of the audio data: level information, loudness information, and spectral information; and generating a display interface according to the extracted acoustic information so as to display the acoustic information of the extracted audio data. For example, a level table as shown in fig. 5 may be generated from the level information; generating a loudness table as shown in fig. 6 from the loudness information; a spectrogram shown in fig. 7 is generated from the spectral information.
The following details specific application scenarios of the embodiments of the present application:
in one embodiment of the present application, a Host software application (hereinafter referred to as Host) installed at a production end (i.e., an audio playing terminal) and a Guest software application (hereinafter referred to as Guest) installed at a mobile end (i.e., an audio effect testing terminal) may be developed according to the method for monitoring audio output effects of the embodiment of the present application.

Visual acoustic information such as loudness information, spectral information, etc. of the audio signal can be seen in the Guest interface.
In one embodiment of the application, the functions of some mobile devices or Solo (single mobile device) of Mute (one-touch Mute) can be freely selected in the Host interface so as to compare the audio output effects of the respective mobile devices.
In one embodiment of the application, both Host and Guest software employ graphical interfaces to provide user interaction. The Host interface may implement the following interaction or interface elements under each operating system through any cross-platform interface technology:
1. A list of signal sources and check boxes corresponding to the individual signal sources, and the interface may be updated automatically as the signal sources increase or decrease, as shown in section 305 of FIG. 3;
2. quality information of the signal source, such as sampling rate, bit depth, code rate, coding format, etc., as shown in part 304 of fig. 3;

In one embodiment of the present application, the Guest interface may implement the following interaction of acoustic information or interface elements through interface technology of the mobile terminal:
1. level meter, as shown in fig. 5;
2. loudness table, as shown in fig. 6;
3. a spectrogram, as shown in fig. 7.
Wherein, the level table, the loudness table and the spectrogram dynamically display contents according to the actual audio input signal of the Guest; the measuring modes of the level table, the loudness table and the spectrogram all adopt international standards, such as EBU (European Broadcasting Union ) series standards of loudness; meanwhile, the level table, the loudness table and the spectrogram support data configured by a user, such as a peak mode or a root mean square mode of level and loudness, frequency scale distribution of a frequency spectrum, analysis threshold values and the like.
In one embodiment of the present application, in a specific technical implementation, host and Guest may implement a producer mode and a consumer mode on a software architecture, where Host is an audio data producer and Guest is an audio data consumer. In the current productivity environment, the hardware environment operated by the Host may be a desktop computer, and the hardware environment operated by the Guest may be a mobile device (such as a mobile phone, a tablet computer, etc.). The primary flow of audio testing may be as follows:
1. A TCP socket server is established at a Guest end, a TCP socket client end and an Audio Sink representing a Host Audio hardware abstraction layer are established at a Host end, and the Guest end prepares an Audio queue to receive Audio data from the Host;
2. after Host hardware and Guest hardware are connected by a standard data line, the Host establishes full duplex connection based on a mobile platform native communication protocol with the Guest by a known technology through a port (such as USB) defined by the data line, and the Guest sends a check data packet to the Host at fixed time through a socket so as to keep connection with the Host;
3. the Host acquires Audio data generated by a local Audio source through an Audio Sink, and sends the Audio data to the Guest through a socket after making the Audio data into a TCP data packet;
4. the Guest receives the audio data packet sent by the Host from the socket, unpacks the audio data packet and sends the audio data packet to an audio queue of the platform for the local play service to take out the audio data for playing, and the audio delay can be controlled by adjusting the size of the buffer zone.
5. After the data line is pulled out, the connection between the Host and the Guest is terminated.
In the embodiment of the application, in order to overcome the limitation of the hearing short-term memory, whether the audio production tool can provide real-time feedback from the terminal equipment is important, so that if the audio is copied to the mobile terminal for testing the output effect after the production end completes the audio production, the real-time feedback is difficult to realize. The technical scheme of the application can realize real-time transmission and simultaneous playing of the audio content of the production end to the mobile terminal equipment, so that the test effect is greatly improved based on the rapid iterative process of 'production-listening-adjusting'.
Meanwhile, as mass platform and model adaptation are the great difficulty brought by mobile terminal market fragmentation to mobile product audio development, the host-client architecture of the manufacturing end and the mobile end can realize multi-machine simultaneous connection, realize real-time terminal switching under the same content, and greatly improve the model adaptation efficiency.
In one embodiment of the present application, the audio effect test terminal may be a device having an audio output function, and may also have a signal processing function, and may be a speaker for test, etc., in addition to a smart phone, a tablet computer, etc.
On the one hand, the application premise of the technical scheme of the embodiment of the application is that the main activities of audio production are carried out on the desktop end of the computer, namely, an audio production tool for music, movie and television animation and interactive entertainment industry is mainly desktop software, often called a digital audio workstation (Digital Audio Workstation), and the interactive mode mainly depends on computer peripherals (such as a keyboard, a mouse and the like). However, with the growth of mobile-side hardware and operating systems, and the growing reliance of users on mobile computing, many emerging audio vendors are always pushing mobile-device-based audio consumer software and small-sized professional software such as synthesizers and effectors, touch screen gesture interactions are the main interaction modes of these software, and voice interactions, AR (Augmented Reality )/VR (Virtual Reality) are also potential new interaction modes, so traditional professional audio vendors also start pushing mobile-side versions of desktop flagship products. Therefore, if the mobile device can be developed into an ecology integrating audio content production and consumption in the future, the audio playing terminal in the embodiment of the application can be a mobile terminal device capable of producing audio and playing audio, for example, the mobile terminal device can produce audio on a tablet computer device and then test the actual audio output effect on a smart phone.
