Sound equipment will develop to intelligence

Those who are engaged in audio work will encounter problems in system debugging and equipment use. A sound system to play a good effect, must go through the system debugging this link. Audio system debugging is mainly to check the working state, level matching, sound pressure level setting, system frequency response, voltage limiter starting point, time delay, feedback suppressor setting and so on. Most of the work is tedious and requires the person in charge of debugging to have corresponding technical foundation and experience, otherwise it is difficult to complete.

Is there such a device that can automatically and intelligently set the relevant parameters according to the site conditions and easily complete the system debugging? In the past, we did not dare to be so extravagant, but now we can boldly put forward the hope that this kind of intelligent audio equipment will be popularized and applied as soon as possible.

In fact, artificial intelligence has already been applied in many fields. Among them, the most sensational ones are auto driving and intelligent robots. Sometimes, intelligent machines can defeat the human brain. For example, the famous "dark blue" computer defeats the chess master, which has been talked about with relish.

Today's audio equipment has long abandoned analog circuit and digital circuit technology, large-scale integrated circuit technology makes CPU easy to implant into the device, and this kind of chip implantation similar to microcomputer, no doubt, can not only improve the comprehensive performance of the equipment, but also make the audio equipment become smart is no longer so far away.

But the question is whether our R & D personnel in the audio industry have such a perception. At present, most of the equipment in the audio industry is very low in intelligence, and most of them are still at the level of equipment. Networking and informatization seem to have just begun, let alone intellectualization. To say automation, it is just some data mode calls without intelligence. However, there are very few such devices and so-called application scenario patterns. This makes a large number of sound system debugging, use become only a few people can complete things, but also seriously restricted those large theater, performance venues a large number of high-end equipment performance and high-level use of high-frequency.

It must be pointed out that the research and development of intelligent machines has gone through a tortuous road. In theory, most of the intelligent machines used to store the actual application situations in the machines exhaustively. Then, they compared the actual application situations with those in the memory to find out the similar or appropriate mode to enable. It has been proved that this kind of thinking will soon come to the dead end of intelligent machine development. On the one hand, it is difficult to exhaust the application scenarios in reality, that is, no amount of storage mode can meet the actual application; on the other hand, this exhaustive thinking can not give full play to the advantages of the computer numerical calculation. Therefore, the research and development of intelligent machines can only take another way, that is, continuously use the data collected by various sensors, compare with the reference data, adjust the output (action), and then correct the output (action) by calculating and comparing the data collected by the sensor with the reference data, so as to correct the output (action). This process is very fast, and can realize the reaction action similar to the human brain. Calculation and judgment are the strengths of the computer, which makes the machine intelligence out of the dead end and has a bright future.

Obviously, the intellectualization of audio equipment must also take such a road, such as frequency equalization, voltage limit adjustment, feedback suppression, reverberation adjustment, etc. if those tedious and complex tasks are simplified to the level of one button solution, would it not be a revolutionary change. Of course, the author does not mean to belittle the subjective ability of technical personnel, nor does it involve the artistic creation of senior tuners, just as the automatic control technology does not involve the extraordinary driving skills of superb racing drivers.

Fortunately, the author's idea has been verified by an automatic feedback suppressor. It is the use of new machine intelligence principle, through this intelligent feedback suppressor to suppress feedback whistling in real time and on the spot.

"A single spark can start a prairie fire", although it is only an intelligent audio peripheral equipment, but it brings us immeasurable enlightenment. Therefore, audio equipment must develop to intelligence!
