In the current sound modification circle, DSP power amplifier in many upgrade scenarios, has replaced the host, power amplifier, has become a sharp tool to modify, improve and enhance the sound source, sound field. A multi-purpose cost-effective, simple and easy to produce results, these advantages make the DSP power amplifier a new favorite of the store, the owner's favorite.
Tuning around the DSP has not come out of the experience area of relying on hearing and tuning parameters, for many skilled mixers, without exception, they are through the software to adjust the DSP's EQ, delay, filter and other three-plate axes to optimize the sound field in the car to meet the individual needs of customers.
The problem is that there are a variety of models on the market, there are SUVs, cars, MPVs, etc., the horn and space acoustic characteristics are different, the tuner for their own unfamiliar models, can not understand the acoustic characteristics of the model and the sound characteristics of the horn in time, it is bound to spend a lot of time to explore, repeatedly do different settings, audition, but it is difficult to target the precise tuning.
Experience is not always reliable, and if the tuner is in a bad mood today, or if the master takes a leave of absence today to change people, it will affect the tuning effect. Car owners are not satisfied, affecting the reputation of the store. How to make the tone change tuning become a well-founded scientific setting process, so that all the mixers in the store are proficient, so that the tuning becomes standard and reliable?
As the industry's oldest DSP solution provider (founded in 2010, it is the behind-the-scenes "sound" of many popular brands in the market). Based on scientific algorithms, the DSP intelligent tuning assistant was launched for the first time, which can help the mixer accurately and quickly understand the acoustic characteristics of each horn in a specific position in each specific car, so that the tuner can quickly and accurately help the owner to optimize the soundstage, greatly improve the installation and debugging efficiency, and greatly improve the satisfaction of the owner.
It is understood that after years of research, Gelosheng has developed a set of algorithms that automatically test the characteristics of loudspeakers and spatial sound frequencies, and can display the sound frequency curves of each horn, so that the tuner can accurately understand the acoustic characteristics of each horn in the car and provide a scientific basis for its accurate tuning.
The principle is: some specific noise sequences are generated by the DSP, and the acoustic response from the speaker is retrieved by the microphone back to the DSP, which is analyzed by the DSP, and the sound frequency characteristics of each speaker are displayed on the PC display in the form of a curve as an objective basis for the tuner's accurate tuning. At the same time, DSP can calculate the compensation curve of the horn according to the obtained sound frequency response characteristics, optimize the volume and delay of the speaker, etc., which can be used as a reference scheme for the tuner to optimize the setting of the sound field, on this basis, the tuner can then meet some personalized customization needs of the owner through fine tuning. The whole process only requires the user or rear speaker to connect the delivered microphone during debugging, place the microphone in the target best listening position, and then press the button, after a few minutes of testing and calculation, and then complete. In this process, if it is found that the horn is not connected or the polarity is reversed, the tuner will be prompted to check or automatically correct it through the DSP software.
If the tuner or owner has their own customized special audio characteristic curve requirements, you can also adjust the 31-segment EQ before the test to complete the target curve setting, and then perform the test and automatic optimization process. There is no doubt that with the GRAM SOUND DSP intelligent tuning assistant algorithm, stores and mixers no longer need to buy expensive debugging test instruments to quickly and easily accurately understand the sound and frequency characteristics of each horn of each car, greatly improving the efficiency of installation and debugging, shortening the delivery time, and improving service satisfaction.
Functions and features of Gelosheng Intelligent Tuning Assistant:
1. Detect the characteristic curve of the horn, accurately identify the frequency cutting point of the three-way horn, and facilitate the tuner to understand the characteristics of the horn.
2. Automatically detect the polarity of the horn to prevent the sound abnormality caused by the reverse phase of the horn during the modification process.
3. Automatically detect the delay of the driving position and the distance between the horns (the error is less than 1cm), and the sound field of the emperor can be reached without measurement.

Summary: If tuning is regarded as the creation of a work, the Gelvote DSP intelligent tuning assistant is to use advanced tools to complete the routine basic work in a more scientific and efficient way. According to his understanding of music and his grasp of customer needs, the tuning done by the tuner is the finishing touch. The Gryonic DSP Tuning Assistant frees the tuner from tedious routine work, allowing more time and energy to focus on the real needs and preferences of customers and improve customer satisfaction to a greater extent.
