First, a sound effect debugging method provided by the embodiment of the invention is described below.

As shown in fig. 1, the audio debugging system includes a vehicle-mounted host 110 and a terminal 120, the vehicle-mounted host 110 includes a processing chip 111, an audio processing chip 112 and a built-in power amplifier chip 113, the terminal 120 is in communication connection with the processing chip 111, and the processing chip 111, the audio processing chip 112 and the built-in power amplifier chip 113 are electrically connected in sequence.
When the vehicle-mounted host plays audio after being put into formal use, the audio processing chip processes audio data according to the adjusted audio parameters, and then plays the processed audio data after power amplification is carried out through the built-in power amplifier chip. The processing chip may also be electrically connected to the built-in power amplifier chip to control initialization of the built-in power amplifier chip, adjust audio playing volume, perform diagnosis, and the like, which is not limited herein. In the sound effect debugging process, the audio parameters of the audio processing chip need to be adjusted, so that a better audio playing effect can be achieved when the vehicle-mounted host plays audio after being put into formal use.
As shown in fig. 2, a sound effect debugging method is applied to a processing chip in a vehicle-mounted host included in an audio debugging system, and the method includes:
s201, sound effect debugging data sent by the terminal are obtained;
and the sound effect debugging data is determined by the terminal according to the adjustment data input by the user based on the interface displayed by the terminal.
S202, processing the sound effect debugging data and determining an adjusting parameter;
and S203, sending a debugging instruction to the audio processing chip to enable the audio processing chip to adjust audio parameters according to the adjustment parameters, so that when the vehicle-mounted host plays audio, the audio processing chip processes audio data according to the adjusted audio parameters, and then plays the processed audio data through the built-in power amplifier chip.
And the debugging instruction carries the adjusting parameter.
It can be seen that in the scheme provided in the embodiment of the present invention, the processing chip may obtain the audio debugging data sent by the terminal, where the audio debugging data is determined by the terminal according to the adjustment data input by the user based on the interface displayed by the terminal, process the audio debugging data, determine the adjustment parameter, and send the debugging instruction to the audio processing chip, so that the audio processing chip adjusts the audio parameter according to the adjustment parameter, so that the audio processing chip processes the audio data according to the adjusted audio parameter when the vehicle-mounted host plays the audio, and then plays the processed audio data through the built-in power amplifier chip, where the debugging instruction carries the adjustment parameter. By adopting the scheme, the user can input the adjustment data in the interface displayed by the terminal, the processing chip can acquire the sound effect debugging data sent by the terminal, and then determines the adjustment parameters and sends the adjustment parameters to the audio processing chip to adjust the audio parameters.
The terminal may be a computer, a mobile phone, a tablet computer, and the like, and is not limited specifically herein. In order to conveniently debug the sound effect, sound effect debugging software can be installed in the terminal in advance, so that when the sound effect debugging is needed to be carried out on an audio processing chip of a certain vehicle-mounted host, the terminal can be in communication connection with the processing chip in the vehicle-mounted host so as to transmit data.
In an embodiment, the terminal may be in communication connection with a processing chip in the vehicle-mounted host through a UART (Universal Asynchronous Receiver/Transmitter) port by using a serial port, and since the UART port is an inherent interface of the vehicle-mounted host, the terminal may also recognize a port number thereof, which may facilitate communication between the terminal and the processing chip in the vehicle-mounted host. The processing chip may be electrically connected to the audio processing chip through an SPI (Serial Peripheral Interface) port, which is a synchronous Serial port for communication between the processing chip and the Peripheral device. The processing chip and the built-in power amplifier chip can be electrically connected through an IIC bus, and the audio processing chip can be electrically connected with the built-in power amplifier chip through a TDM (Testing Data Management/Technical Data Management, time division multiplexing mode) port.
Specifically, the processing chip may be electrically connected to the audio processing chip through an SPI bus, which is a full-duplex synchronous serial bus. The IIC bus is a simple, bi-directional two-wire synchronous serial bus for transmitting data between devices connected to the IIC bus. The audio processing chip can be electrically connected with the built-in power amplifier chip through a TDM bus, wherein the TDM bus is mainly used for transmitting audio data of more than two channels on the same data line.
The vehicle-mounted host can be connected to the whole vehicle environment through the plug-in, and the whole vehicle supplies power to the vehicle-mounted host through the wiring harness and the plug-in. After the processing chip is powered on, the UART port and the SPI port can be initialized. The processing chip can call the driving component of the audio processing chip, and initialize the input interface and the output interface of the audio processing chip and the volume configuration of the sound source, the main channel, the navigation channel and the telephone channel. The processing chip can also call the IIC driving component to initialize the input interface, the output interface, the volume configuration and the like of the built-in power amplifier chip so as to conveniently debug the sound effect of the audio processing chip.
The user can input the adjustment data in the sound effect debugging software interface displayed on the terminal according to actual needs, and the user can be a technician such as a disc-jockey and the like without specific limitation. The adjustment data may include a frequency point, a frequency, a Q value, a gain, and the like of the audio processing chip.
The main channel of the audio processing chip generally supports adjustment of gains of 9 frequency points, for example, if the 1 st frequency point needs to be adjusted, adjustment data corresponding to the frequency point may be set to 1. The frequency is a frequency value corresponding to a certain frequency point, for example, the frequency value of the 1 st frequency point needs to be adjusted to 200Hz, and then the adjustment data of the frequency can be set to 200. The Q value is a quality factor, and the larger the Q value is, the steeper the frequency response curve corresponding to the audio processing chip is; the smaller the Q value is, the flatter the frequency response curve corresponding to the audio processing chip is. The gain (Gdb) is the DB (Decibel) value that is added or attenuated for a certain frequency.
For example, the adjustment data set in the sound effect debugging software interface displayed by the terminal by the user is the frequency point: 1, frequency: 200, Q value: 2.5, gdb:3. the terminal can acquire the adjustment data, and then determine sound effect debugging data based on the requirements such as the communication format between the terminal and the processing chip, and send the sound effect debugging data to the processing chip, and the processing chip can acquire the sound effect debugging data.
The processing chip may be a chip capable of processing sound effect debugging data, such as an MCU (Micro Control Unit), and is not specifically limited and described herein. After the processing chip obtains the sound effect debugging data, the processing chip may execute the step 202, that is, process the sound effect debugging data, and determine the adjustment parameters.
Due to the limitation of communication format and the like, the data format sent by the terminal to the processing chip may be different from the data format which can be identified and processed by the audio processing chip, so that in order to enable the audio processing chip to smoothly and accurately analyze the data sent by the processing chip, the processing chip can process the sound effect debugging data to obtain the adjustment parameters which can be smoothly transmitted to the audio processing chip.
In step 203, the processing chip may send a debugging instruction to the audio processing chip, where the debugging instruction carries the adjustment parameter. Therefore, after the audio processing chip receives the debugging instruction, the audio parameters can be adjusted according to the adjustment parameters, so that after the vehicle-mounted host is formally put into use, when the audio is played, the audio processing chip can process the audio data to be played according to the adjusted audio parameters, and then the processed audio data is played through the built-in power amplifier chip, and a good audio playing effect is achieved.
In the scheme provided by the embodiment of the invention, the audio parameter adjustment is not directly carried out on the audio processing chip, so that an upper computer is not needed, technical personnel support of an audio processing chip manufacturer is not needed, and the efficiency of the audio debugging process of the audio processing chip can be improved.
As an implementation manner of the embodiment of the present invention, as shown in fig. 3, the step of processing the sound effect debugging data and determining the adjustment parameter may include:
s301, analyzing the sound effect debugging data to obtain analyzed debugging data;
after the processing chip acquires the sound effect debugging data, the sound effect debugging data can be analyzed according to the communication format requirement between the processing chip and the terminal. In one embodiment, the Q value and the gain may be floating point numbers, and the terminal may amplify the two values by 10 times and send the amplified values to the processing chip in an integer form. The processing chip may parse the received sound effect debugging data, and in particular, may restore the Q value and the gain to floating point numbers.
S302, the analyzed debugging data is converted into a register value corresponding to a register of the audio processing chip and used as an adjusting parameter.
Since the audio parameter adjustment of the audio processing chip is realized by adjusting the value of the register, in one embodiment, the processing chip may perform calculation according to a formula required by a manual of the audio processing chip or a formula provided by an audio processing chip manufacturer, convert the analyzed debugging data into a register value corresponding to the register of the audio processing chip, and use the register value as an adjustment parameter.
Therefore, in this embodiment, the processing chip analyzes the sound effect debugging data to obtain analyzed debugging data, and then converts the analyzed debugging data into a register value corresponding to a register of the audio processing chip, which is used as an adjustment parameter. Therefore, after the audio processing chip receives the adjustment parameter, the audio parameter can be accurately and quickly adjusted.
As an implementation manner of the embodiment of the present invention, a manner of adjusting the audio parameter by the audio processing chip may include:
and writing the register value into a corresponding register to adjust the frequency response curve of the audio output by the audio processing chip.
After the audio processing chip receives the debugging instruction sent by the processing chip, the debugging instruction is analyzed, so that the adjusting parameter carried by the debugging instruction, namely the register value, can be obtained. Furthermore, the audio processing chip can write the register value into the corresponding register, so that the frequency, the Q value and the gain of the corresponding frequency point are adjusted, and the purpose of adjusting the frequency response curve of the audio output by the audio processing chip is achieved.
It can be seen that, in this embodiment, the audio processing chip may write the register value into the corresponding register to adjust the frequency response curve of the output audio. Therefore, the playing effect of the audio can be simply and quickly adjusted, and the sound effect debugging efficiency is higher.
As an implementation manner of the embodiment of the present invention, as shown in fig. 4, the step of sending the debugging instruction to the audio processing chip may include:
s401, packaging the adjustment parameters to obtain packaged data;
after the processing chip determines the register value corresponding to the register of the audio processing chip, i.e. the adjustment parameter, the adjustment parameter can be encapsulated to obtain encapsulated data. For example, the adjustment parameters may be encapsulated to obtain a frame of data.
S402, sending a debugging instruction to the audio processing chip according to the communication format between the processing chip and the audio processing chip.
Furthermore, the processing chip can send a debugging instruction to the audio processing chip according to the communication format between the processing chip and the audio processing chip, wherein the debugging instruction carries the packaged data. In an embodiment, the processing chip and the audio processing chip communicate with each other through the SPI port, so that the processing chip may send a frame of data, which is the encapsulated data, to the audio processing chip as a debugging instruction according to a communication format corresponding to the SPI port.
As can be seen, in this embodiment, the processing chip may package the adjustment parameter to obtain packaged data, and then send a debugging instruction to the audio processing chip according to a communication format between the processing chip and the audio processing chip. Therefore, the processing chip can accurately and smoothly send the packaged adjustment parameters to the audio processing chip, and the accuracy and efficiency of sound effect debugging are ensured.
As an implementation manner of the embodiment of the present invention, as shown in fig. 5, a manner of determining the sound effect debugging data by the terminal may include:
s501, acquiring adjustment data input by a user based on an interface displayed by the terminal;

The user may enter adjustment data in the interface that requires adjustment.
For example, as shown in fig. 6, the sound effect debugging interface may include an adjustment data input box, which may specifically be a frequency point input box 610, a frequency input box 620, a Q value input box 630, and a gain input box 640. The user may input corresponding values in the frequency point input box 610, the frequency input box 620, the Q value input box 630, and the gain input box 640, and the terminal may acquire the values input by the user as adjustment data.
S502, processing the adjusting data according to the communication format between the terminal and the processing chip to obtain the sound effect debugging data.
After the adjustment data is obtained, in order to ensure that the adjustment data can be successfully and accurately sent to the processing chip, the terminal can process the adjustment data according to a communication format between the terminal and the processing chip to obtain sound effect debugging data.
In one embodiment, the communication format between the terminal and the processing chip can be as shown in the following table:
| frame header | Frequency point | Frequency of | Q value | Gain of | Checksum |
| 4Byte | 1Byte | 2Byte | 1Byte | 1Byte | 1Byte |
The frame header is in a fixed format, and may be "echo" or the like, for example. The frequency point range, the frequency range, the Q value range and the gain range can be determined according to the hardware parameters of the audio processing chip. In one case, the frequency bin range may be 1-9, the frequency range may be 20Hz-20KHz, the Q range may be 0-9.9, and the gain range may be-9.9 DB-9.9DB.
As an embodiment, the checksum may be an accumulated sum of a frequency point, a frequency, a Q value, and a gain, so as to facilitate the verification. Since the Q value and the gain may be floating point numbers and are generally in a one-decimal format for convenient transmission, the terminal may amplify the Q value and the gain by 10 times and transmit in an integer format. If the gain is negative, then it may be sent in complementary format.
For example, the adjustment data input by the user is frequency point: 2; frequency: 30Hz; q value: 3.7; gain: 5.9DB. The terminal may determine the sound effect debugging data as follows:
| frame header | Frequency point | Frequency of | Q value | Gain of | Checksum |
| echo | 2 | 30 | 37 | 59 | 128 |
Therefore, in this embodiment, the terminal may obtain the adjustment data input by the user based on the interface, and further process the adjustment data according to the communication format between the terminal and the processing chip to obtain the sound effect debugging data. Therefore, smooth communication between the terminal and the processing can be ensured, the audio debugging data can be accurately sent to the processing chip, and the accuracy and efficiency of the sound effect debugging process are ensured.
As an implementation manner of the embodiment of the present invention, as shown in fig. 7, the step of acquiring the sound effect debugging data sent by the terminal may include:
