Professional audio systems are gradually becoming intelligent.Bar lighting speaker Vendor

　　Professional audio equipment friends who are engaged in audio work will encounter problems with system debugging and equipment use. For a set of professional audio equipment to produce a sound system, it must go through the link of system debugging. Audio system debugging is mainly to check the working status, level matching, sound pressure level setting and system frequency response of the system, the starting point of the compressor, the delay, and the adjustment of the feedback suppressor. Most of the work is tedious and requires the person in charge of debugging to have the corresponding technical foundation and experience, otherwise it will be difficult to complete.

　　Is there such a device that can automatically set the relevant parameters intelligently according to the on-site conditions, and easily handle the system debugging? We did not dare to have such a luxury before, but now we can boldly propose it and look forward to the early popularization of this kind of smart audio equipment application.

　　In fact, artificial intelligence has already been applied in many fields. Among them, the most sensational effects can be regarded as auto-driving cars and intelligent robots. And sometimes, intelligent machines can defeat the human brain. For example, the famous "Deep Blue" computer defeats chess masters. , Has been talked about by people.

　　The current audio equipment has long abandoned analog and digital circuit technology. Large-scale integrated circuit technology makes it easy to implant the CPU into the device. And this kind of microcomputer-like chip implantation can undoubtedly not only improve the equipment. This kind of comprehensive performance, while making audio equipment smart is no longer so far away.

　　But the question is, do our R&D personnel in the audio industry have such awareness. 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 intelligent. To say that automation is actually just some There is no intelligent data mode call. Nevertheless, such devices are pitiful, and so-called application scenarios are also pitiful. This makes a large number of debugging and use things that only a few people can complete, and it also severely restricts the performance of a large number of high-end equipment in large theaters and performing arts venues and the high-frequency and high-level use.

　　It must be pointed out that the research and development of smart machines has also gone through a detour. In the past, most smart machines were theoretically used by R&D personnel to exhaustively store actual applications in the machine, and then the actual application and storage at the time. Compare the scenes in the memory to find a similar or suitable mode to start. Facts have proved that this kind of thinking quickly entered a dead end in the research and development of intelligent machines. On the one hand, it is difficult to exhaust the application scenarios in reality, that is, no amount of storage modes can satisfy practical applications; on the other hand, this exhaustive thinking cannot give play to the advantages of computers-numerical calculations. . Therefore, the research and development of smart machines can only go another way, which is to continuously use the data collected by various sensors to compare with the benchmark data, adjust the output (action), and then calculate and compare the data collected by the sensor with the benchmark data to correct the output ( Action), this process is very fast, enough to achieve a reaction action similar to the human brain. Calculations and judgments are the strengths of computers. This makes machine intelligence out of a dead end and has a bright future.

　　Obviously, the intelligentization of audio equipment must also follow this path, such as audio system frequency equalization, pressure limit adjustment, feedback suppression, reverberation adjustment, etc. Those tedious and complicated tasks can be simplified to the degree of one-click solution. Isn't it a revolutionary change? Of course, the author does not mean to belittle the subjective ability of technicians, nor does it involve the artistic creation of senior tuner, just as automatic driving technology does not involve the extraordinary driving skills of superb racing drivers.
