Embodiment
Below preferred embodiment of the present invention is described in detail.
The invention provides a kind of apparatus for processing audio, as shown in Figure 2, it is arranged in the digital audio processor circuit, described digital audio processor circuit comprises that one connects the power amplifier of audio amplifier, and the processor unit that this power amplifier is provided audio signal, this processor unit can adopt PC or embedded processing systems, in described processor unit, be provided with the control module that is used to control described audio amplifier frequency response curve characteristic, this digital audio processor circuit integral body is provided with level password to be controlled, can be used for field adjustable, and, described control module is realized the modification of sound box parameter operation interface is limited by the secondary cipher control, can be used for the setting of audio amplifier producer.Described audio process circuit can be used for controlling power amplifier and the operation level state of audio amplifier and the Frequency Response curve rectification of audio amplifier etc. on its output channel.
So the time to the parameter adjustment of processor unit, to be limited by the secondary password the adjustment interface of sound box parameter, promptly only professional audio amplifier designer or manufacturer, can not change sound box parameter easily, prevent from the process of revising audio frequency supple-settlement parameter, disorderly to change the hardware parameter of audio amplifier thus, cause the damage formula of equipment is used.
In the apparatus for processing audio of the present invention, during to the interface limitations of described control module, can before the input of described secondary password is correct, hide and do not show or Fuzzy Processing, to prevent that interface parameter is identified and to imitate the appearance situation that prevents to cause palming off audio amplifier easily.
In the apparatus for processing audio of the present invention, described digital audio processor circuit has adopted the digital audio processor of ARM system management and DSP signal processing double-core framework, so system of the present invention has superstability, has ensured the generation of audio discontinuity that sound in the use is not subjected to system's reason and causes, problem such as noiseless.
Simultaneously, described digital audio processor circuit comprises input, route, output three parts, wherein
That described importation comprises is quiet, input gain, equalizer (31 sections diagram is balanced and parametric equalizer is optional) and delayer;
Described routing section comprises and the signal of input channel can be routed to output channel arbitrarily that route proportional quantities and phase place (0-180 °) are turning;
Described output comprises that output gain, the logical control of band, parametric equalizer, compressor, delayer and passage are quiet.
Another bright spot of apparatus for processing audio of the present invention is that freedom is organized into groups debug function easily, and input, output channel can select to organize into groups uniting and adjustment by numeral or symbol, have saved the trouble that passage duplicates, pastes.Simultaneously, secondary password setting function is another bright spot of product of the present invention after the route, can hide frequency response, frequency division, the pressure of system and limit sound box parameters such as data.
Apparatus for processing audio of the present invention adopts liquid crystal display, and adopts Chinese and English interface, so that more meet domestic users' use habit.
The present invention provides the audio-frequency processing method of described apparatus for processing audio simultaneously, and as shown in Figure 3, it may further comprise the steps:
