Description

The most important core device in music recording studios was the large audio system (condole) before nineties of the last century. Beginning in the 90 s, as digital recording and Avid Pro Tools HD systems evolve, the use of large audio systems gradually decreases, but instead adopts microphone-preamplifier-audio effector-AD conversion-computer mode recording; the ITB (In the Box) mode can be used in the audio mixing part, and only the computer and DA mode can be used in the audio mixing part, and only the AD/DA conversion is needed when the hardware sound processing effect is needed to be inserted. In recent years, with the roll of antique climax, classical sounds of an audio system are reminiscent of more and more audio workers, and most recording booths resume using the audio system as a working center for recording and mixing sounds. The hardware effect of the audio system is generally limited to the traditional basic modules of equalization, compression and limitation, and the effects of dynamic EQ, noise gate, complex delay and the like still need a plug-in to be realized. Also, audio systems typically have a limited number of audio effectors, and Hybrid modes in combination with plug-ins are more convenient to operate. However, today audio systems are not ideally combined with digital plugins, and we cannot insert software effectors on any node of the audio system. Thus, there is a need for a device that can be an extension of the audio system to accommodate the current hybrid operating mode: the plug-in can be conveniently called for processing under the advantages of high-quality hardware of the sound console, pleasant classical dyeing and high dynamic allowance summation.

Detailed Description
Most of the existing servers based on the DSP operation audio effect plug-in units have no i/o interface and digital-to-analog/analog conversion, and are required to be expanded additionally; or part of the operation servers are provided with i/o interfaces and analog-to-digital conversion, but the operation servers cannot be independently used, which is equivalent to the externalization and independence of sound cards in computers, and the operation servers cannot be independently used when separated from the computers, and can exert complete functions only through a series of protocols, so that the mode has great binding requirements with digital audio workstation software in the computers, and the operation servers are inconvenient and concise to use.
In view of the foregoing, the present invention provides a sound processing operation server and a sound processing operation method suitable for an audio system, and specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The following description of the exemplary embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses. Techniques and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but should be considered part of the specification where appropriate.
For illustrating the sound processing operation server suitable for the audio system provided by the invention, fig. 1, fig. 2 and fig. 3 show exemplary sound processing operation servers suitable for the audio system according to the embodiment of the invention; fig. 4 illustrates an exemplary method for performing an acoustic processing operation for an audio system according to an embodiment of the present invention.
As shown in fig. 1, fig. 2, and fig. 3 together, the sound processing operation server 100 suitable for an audio system provided by the present invention includes an input module 101 and an output module 102 that can be connected with the audio system in hardware, an analog-to-digital conversion module 103 connected with the input module 101 and the output module 102, an operation module 104 connected with the analog-to-digital conversion module 103, and a general system module 105 controlling the analog-to-digital conversion module 103 and the operation module 104; wherein,,
the input module 101 is configured to receive sound data (also referred to as a sampling signal or sampling audio) output by the audio system;
the general system module 105 is configured to select a sound processing plug-in applicable to the sound data from the operation module according to the pre-acquired user intention data, and determine whether analog-to-digital/digital conversion is required for the sound data according to the sound processing plug-in; in this embodiment, if the sound data is an analog signal, the analog-to-digital conversion unit 1031 in the analog-to-digital conversion module 103 needs to transmit the sound data to convert the analog signal into a digital signal point, and if the sound data is directly in the form of a digital signal, the sound data in the form of the digital signal is directly transmitted to the operation module 104 to directly perform operation;
the analog-to-digital conversion unit 1031 in the analog-to-digital/digital-to-analog conversion module 103 is configured to convert the sound data to be analog-to-digital converted into discrete digital signal points according to the clock frequency of the sound data;
the operation module 104 is configured to perform tuning calculation corresponding to the sound processing plug-in according to the digital signal points and the sound processing plug-in, so as to generate a tuning signal;
the digital-to-analog conversion unit 1032 in the analog-to-digital/digital-to-analog conversion module 103 is configured to convert the tuning signal into an analog signal;
the output module 102 is configured to transmit the analog signal to the audio system to perform digital processing on the audio data in analog form.
Specifically, in this embodiment, the sound data is an output signal of an effector plug-in point of the audio system, that is, the connection is established between the input module and the output module in this embodiment and the audio system, then the input module receives the output signal of the effector plug-in point sent by the audio system, and then performs sound effect processing on the output signal of the effector plug-in point, where it is to be noted that, because the output signal of the effector plug-in point is an electrical signal, when the general system module determines whether to perform analog-to-digital/digital conversion on the sound data according to the sound processing plug-in, it is often determined that analog-to-digital/digital conversion is required; unless the sound data is not an electric signal or an analog signal, or the selected sound processing plug-in unit can directly process the analog signal without analog-to-digital conversion, the current sound processing plug-in units cannot process the analog signal or the electric signal, so that digital-to-analog conversion is required to process tuning.
More specifically, the signal of the plugging point of the effector of the vector audio system enters the input module of the embodiment, and then enters the analog-to-digital conversion unit of the analog-to-digital/digital-to-analog conversion module, and the continuous analog electric signal is sampled into discrete digital signal points according to the clock frequency; next, the digital signal enters an operation module, and the operation module carries out related operations such as convolution operation according to the sound data and the added plug-in and the adjusted content; the signal of the operation result is returned to the digital-to-analog conversion unit in the analog-to-digital conversion module to restore the digital signal into an analog signal, and then the processed and restored signal is returned to the audio system through the output module. Operations such as track or plug-in point selection, plug-in addition/deletion/modification and the like are required to be performed in the universal system module by a user, so that the universal system module can acquire user intention data of the user, and further control the work of other modules.
In this embodiment, the sound processing plug-in is a sub-plug-in the DSP algorithm, and even if the DSP algorithm is used as a core, the cost is easier to control than that of the general CPU, the technology is more mature, and the DSP includes many sub-plug-ins for performing sound effect processing that are already mature, so in this embodiment, the DSP is selected as the core processor of the sound processing plug-in.
In this embodiment, the general system module 105 needs to be equipped with a general CPU for performing various data operations, and is further connected with an operating system, an application program, and a software rendering unit, so as to render an operation interface of a user in the operating system through the software rendering unit, and process data input by the user by configuring the application program to obtain intent data of the user; specifically, the software part includes an operating system, application programs, a software rendering unit, and the like, and the hardware part includes a memory, a central processing unit, a graphics processor, a storage device, and the like. After a user logs in the sound processing operation server suitable for the audio system in the embodiment, the user can use various application programs to add/modify various effect device plug-ins (sub-plug-ins) for the audio system and control the operation of the other two modules; wherein the graphic rendering of the software interface is operated by a graphic processor, and the opening of the software requires the operation of a central processing unit and a memory.
And the operation module 104 performs tuning calculation corresponding to the sound processing plug-in according to the digital signal points and the sound processing plug-in to generate tuning signals, namely performing operations such as convolution of digital quantized audio according to plug-ins and parameters added or modified by a user in the control application program, and transmitting a rendered operation result to a digital-to-analog conversion unit in the analog-to-digital conversion module.
In addition, it should be noted that the DSP does not participate in the operations of controlling the software interface and other functions, and the sound processing operation system needs to be compatible with plug-ins of multiple manufacturers such as mainstream waves, UAD, plug in Alliance, etc.; meanwhile, the acoustic processing operation is performed on the digital signals, the analog signals acquired by all nodes of the audio system are required to be converted into digital signals, and accurate sampling of each node is ensured, so that the digital-to-analog conversion has to have high sampling precision (for example, 32 bits are adopted), and the sampling rate can be adjusted. And a very high-precision clock is required to be built in, for example, the JetPLL II double-precision clock technology of Avid, so that the synchronization of each sampling point is ensured.
In this embodiment, the operation module, the general-purpose system module, the operating system, the application program, and the software rendering unit are integrated in a central processor.
