Description
Technical Field
The invention relates to the technical field of tuning, in particular to a method, playing equipment, a server and a system for loading tuning parameters.
Background
The loading method of the tuning parameters in the prior art generally stores the tuning parameters in the form of a hexadecimal digital bin file in the playing device.
When the tuning algorithm module loads the corresponding tuning parameters from the bin file, it does not know which line of the corresponding tuning parameters in the bin file, but is specified by a developer when writing a program. For example: the parameters corresponding to the first tuning algorithm module may be pre-specified as the 1 st byte to the 20 th byte of the bin file, and the parameters corresponding to the second tuning algorithm module may be specified as the 21 st byte to the 40 th byte of the bin file.
However, the relationship of the tuning parameters to the tuning algorithm module is implicitly fixed in the program of the playback device. While this implicit relationship is non-stationary. In the above example, if the byte number of the tuning parameter corresponding to the first tuning algorithm module is changed from 20 bytes to 16 bytes, the positions of the parameters corresponding to all the subsequent tuning algorithm modules will be changed. The relation previously solidified in the program is not effective any more, so that the tuning algorithm module needs to be correspondingly changed, and the coupling between the tuning parameters and the tuning algorithm module is high. When the data structure of the tuning parameters needs to be modified, the tuning algorithm module needs to be matched and modified. This creates unnecessary work.

< first embodiment >
< method >
In this embodiment, a method for loading tuning parameters is provided, which is implemented by a playback device.
The playing device may be any electronic device having a speaker, a processor and a memory, for example, a mobile phone, a tablet computer, an MP3, a sound box, a notebook computer, etc. In one example, the server may be the playback device 1200 shown in FIG. 1.
The method for loading tuning parameters, as shown in fig. 2, includes: step S2100.
And step S2100, acquiring a conversion file reflecting the corresponding relation between the tuning parameters and the tuning algorithm modules and the tuning sequence of the tuning algorithm modules.
The tuning algorithm module can adjust the gain of the corresponding frequency band of the audio signal input to the tuning algorithm module by loading the corresponding tuning parameters, so as to make up for the frequency band with too high or too low frequency in the frequency response curve.
Specifically, the conversion file may be obtained from the server in a wired or wireless manner. For example, the conversion file stored in the server may be actively copied to the playback device by the developer. Or the server transmits the conversion file to the playing device.
In one example, after the server generates the converted file, the server encrypts the converted file according to a preset encryption algorithm. Then, step S2100 may further include steps S2110-S2120 as shown in fig. 3:
step S2110, an encrypted conversion file is acquired.
The encrypted conversion file is obtained by encrypting the conversion file by the server according to a preset encryption algorithm. The step of obtaining the encrypted conversion file may refer to the step of obtaining the conversion file, and is not described herein again.
Step S2120, the encrypted converted file is decrypted according to a preset key, and the converted file is obtained.
Specifically, the preset secret key corresponds to an encryption algorithm for encrypting the converted file in the server, and according to the secret key, the encrypted converted file obtained by encrypting through the corresponding encryption algorithm can be decrypted to obtain the converted file.
Step S2200 is to analyze the conversion file to obtain the tuning parameters corresponding to each tuning algorithm module and the tuning sequence of the tuning algorithm modules.
Specifically, the tuning parameters corresponding to each tuning algorithm module can be obtained by analyzing the conversion file according to the label and the key value thereof, wherein the tuning parameters corresponding to each tuning algorithm module can be hexadecimal numbers. And according to the label sequence, obtaining the tuning sequence of the corresponding tuning algorithm module.
For example, the conversion file may be a JSON file, and the contents in the JSON file may be: "threshold _ low": 38, "ratio _ low":100, "knee _ low":0, "makeup _ low":3, 1. This indicates that the tuning parameter corresponding to the tuning algorithm module "thres _ low" is-38, the tuning parameter corresponding to the tuning algorithm module "ratio _ low" is 100, the tuning parameter corresponding to the tuning algorithm module "knee _ low" is 0, and the tuning parameter corresponding to the tuning algorithm module "makeup _ low" is 3, 1. Parsing the conversion file may include converting the tuning parameters corresponding to each tuning algorithm module into hexadecimal numbers.
The tuning sequence can be tuning algorithm module "thres _ low", tuning algorithm module "ratio _ low", tuning algorithm module "knee _ low", and tuning algorithm module "makeup _ low".
And step S2300, controlling each tuning algorithm module to load the corresponding tuning parameters, and carrying out tuning processing on the input audio signals according to the tuning sequence.
Specifically, the parsed tuning parameters corresponding to the at least one tuning algorithm module may be provided to the corresponding tuning algorithm module. For example, a first tuning parameter corresponding to a first tuning algorithm module may be provided to the first tuning algorithm module, a second tuning parameter corresponding to a second tuning algorithm module may be provided to the second tuning algorithm module, and a third tuning parameter corresponding to a third tuning algorithm module may be provided to the third tuning algorithm module.
Under the condition that the tuning sequence is a first tuning algorithm module, a second tuning algorithm module and a third tuning algorithm module, the first tuning algorithm module can load a first tuning parameter to carry out tuning processing on an input audio signal to obtain a first tuning signal; the second tuning algorithm module loads a second tuning parameter to carry out tuning processing on the first tuning signal to obtain a second tuning signal; and the third tuning algorithm module loads a third tuning parameter to perform tuning processing on the second tuning signal to obtain a third tuning signal and outputs the third tuning signal to sound production components such as a loudspeaker for playing.
Under the condition that the tuning sequence is the second tuning algorithm module, the third tuning algorithm module and the first tuning algorithm module, the second tuning algorithm module can load a second tuning parameter to perform tuning processing on the input audio signal to obtain a fourth tuning signal; the third tuning algorithm module loads a third tuning parameter to perform tuning processing on the fourth tuning signal to obtain a fifth tuning signal; and the first tuning algorithm module loads the first tuning parameters to carry out tuning processing on the fifth tuning signal, so that a sixth tuning signal is obtained and is output to sound production components such as a loudspeaker to be played.
In one example, the server may perform format conversion processing on an identification code of a pre-authorized playback device as an authorized identification code into a conversion file. Then, the method may further include steps S4100-S4300 as shown in fig. 4:
step S4100, obtain the current identification code of the playback device.
The current identification code may be a MAC address or serial number that uniquely identifies the playback device.
In step S4200, the authorized identification code is acquired.
Wherein, the authorized identification code is the identification code of the preauthorized playing device.
The authorization identification code may be obtained when the conversion file is parsed, acquired from a server, or pre-stored in the playback device, for example.
The authorized identification code may be an identification code of each pre-authorized playback device, or may be a range of identification codes of a plurality of pre-authorized playback devices.
Step S4300, compare the current identification code of the playback device with the authorized identification code.
In an embodiment where the authorized identification codes include the identification code of each preauthorized playback device, the identification codes of the preauthorized playback devices may be traversed to compare with the current identification code of the playback device, and if the current identification code is included in the authorized identification codes, indicating that the current identification code matches the authorized identification code, the playback device may be determined to be preauthorized. If the current identification code is not included in the authorized identification code, indicating that the current identification code does not match the authorized identification code, it can be determined that the playback device is not pre-authorized.
For example, the authorized identification code is 1, 3, or 5, and if the current identification code is any one of 1, 3, or 5, it can be determined that the current identification code matches the authorized identification code, and the playback device is pre-authorized. If the current identification code is an identification code other than 1, 3, and 5, for example, 2, it can be determined that the current identification code does not match the authorized identification code, and the playback device is not pre-authorized.
In an embodiment where the authorized identification code is a range of identification codes of multiple pre-authorized playback devices, it may be determined whether the current identification code is within the range. If the current identification code is within the range, indicating that the current identification code matches the authorized identification code, it may be determined that the playback device is pre-authorized. If the current identification code is within the range, indicating that the current identification code does not match the authorized identification code, it may be determined that the playback device is not pre-authorized.
For example, the range is 1-5, and if the current identification code is any one of 1, 2, 3, 4, and 5, it can be determined that the current identification code is within the range, and the playback device is pre-authorized. When the current identification code has another value, for example, 6, it can be determined that the current identification code does not match the authorized identification code, and it can be determined that the playback device has not been preauthorized.
In one example, the step S2300 is performed when the current identification code matches the authorized identification code.
In one example, the playback device may store, in advance, the tuning sequences of the partial tuning algorithm modules and the initial tuning parameters corresponding to each of the partial tuning algorithm modules. The initial tuning parameters corresponding to one of the tuning algorithm modules may be different from the tuning parameters corresponding to the tuning algorithm module contained in the conversion file.
And under the condition that the current identification code is not matched with the authorized identification code, controlling the part of tuning algorithm modules to call the corresponding initial tuning parameters, and carrying out tuning processing on the input audio signal according to a preset tuning sequence. That is, under the condition that the playing device is not authorized in advance, the tuning parameters and the tuning sequence contained in the conversion file acquired by the tuning algorithm module cannot be controlled to perform tuning processing on the input audio signal. But only part of the tuning algorithm modules can be controlled to call the corresponding initial tuning parameters to carry out tuning processing on the input audio signals according to the preset tuning sequence.
In the case that the current identification code does not match the authorized identification code, step S2300 may be performed within a preset time limit. The period may be, for example, 1 month. The usage time of the playback device can then be determined by a timer in the playback device. If the service time exceeds the time limit, the tuning algorithm module can not be controlled to call the tuning parameters contained in the conversion file to carry out tuning processing on the input audio signal. Further, when a preset time limit is exceeded, the partial tuning algorithm module is controlled to call the corresponding initial tuning parameters according to a preset tuning sequence to perform tuning processing on the input audio signal.
In one example, the method may further include steps S5100-S5200 as shown in fig. 5:
in step S5100, an event that the conversion file is modified is detected.
Specifically, the server may send a modification notification to the playback device when the conversion file is modified, so that the playback device detects that the conversion file is modified. The playing device may also inquire the server whether the converted file is modified according to a preset frequency.
In step S5200, the modified conversion file is obtained from the server and updated according to the detection result of the event.
Specifically, when an event that the conversion file is modified is detected, the modified conversion file may be retrieved from the server for updating. The updating step may include re-analyzing the modified conversion file, and providing the analyzed tuning parameters corresponding to each tuning algorithm module and the new tuning sequence to the corresponding tuning algorithm module, so as to control the tuning algorithm module to perform tuning processing according to the new tuning sequence when the audio signal is input again.

< second embodiment >
< method >
In this embodiment, a method for loading tuning parameters is provided, which is implemented by a server.
The server may be any electronic device having a processor and a memory, for example, a desktop computer, a blade server, a cloud server, etc. In one example, the server may be the server 1100 shown in FIG. 1.
The method for loading tuning parameters, as shown in fig. 7, includes: step S7100.
And S7100, responding to the operation of carrying out format conversion on the preset tuning parameters, carrying out format conversion processing on the tuning parameters according to the corresponding relation between the preset tuning parameters and the tuning algorithm modules arranged in the playing equipment and the sequence of the tuning algorithm modules, and obtaining a conversion file reflecting the corresponding relation between the tuning parameters and the tuning algorithm modules and the tuning sequence of the tuning algorithm modules for the playing equipment to obtain.
Specifically, one or more tuning algorithm modules may be disposed in the playback device. The server may store tuning parameters corresponding to at least one tuning algorithm module in the playback device in advance. For example, a first tuning algorithm module, a second tuning algorithm module and a third tuning algorithm module may be provided in the playback device. The server is pre-stored with tuning parameters corresponding to the first tuning algorithm module and tuning parameters corresponding to the second tuning algorithm module, or with tuning parameters corresponding to the first tuning algorithm module, tuning parameters corresponding to the second tuning algorithm module, and tuning parameters corresponding to the third tuning algorithm module.
The tuning parameters corresponding to the at least one tuning algorithm module may be stored in the server in the form of a bin file. Each tuning parameter may be a hexadecimal number.
The operation of format conversion of the preset tuning parameters may be performed by a developer.
The correspondence between the tuning parameters and the tuning algorithm modules provided in the playback device may be specified by a developer. Specifically, the input may be input by a developer through a device such as a keyboard, a mouse, or a touch screen of the server.
In one example, the correspondence between the tuning parameters and the tuning algorithm modules provided in the playback device may be a byte range corresponding to each tuning algorithm module in hexadecimal numbers contained in the bin file. For example, the correspondence between the tuning parameters and the tuning algorithm modules provided in the playback device may include: the tuning parameter corresponding to the first tuning algorithm module is the 1 st byte to the 20 th byte in the bin file, and the tuning parameter corresponding to the second tuning algorithm module is the 21 st byte to the 40 th byte in the bin file.
And a plurality of tuning algorithm modules in the playing device can perform tuning processing on the input audio signals according to the corresponding tuning sequence.
For example, when the tuning sequence is the first tuning algorithm module, the second tuning algorithm module, and the third tuning algorithm module, the first tuning algorithm module may perform tuning processing on the input audio signal to obtain a first tuning signal; the second tuning algorithm module is used for carrying out tuning processing on the first tuning signal to obtain a second tuning signal; and the third tuning algorithm module is used for tuning the second tuning signal to obtain a third tuning signal and outputting the third tuning signal to sound production components such as a loudspeaker and the like for playing.
Under the condition that the tuning sequence is the second tuning algorithm module, the third tuning algorithm module and the first tuning algorithm module, the second tuning algorithm module can perform tuning processing on the input audio signal to obtain a fourth tuning signal; the third tuning algorithm module is used for carrying out tuning processing on the fourth tuning signal to obtain a fifth tuning signal; and the first tuning algorithm module is used for tuning the fifth tuning signal to obtain a sixth tuning signal and outputting the sixth tuning signal to sound production components such as a loudspeaker for playing.
And carrying out format conversion processing on the tuning parameters according to the corresponding relation between the pre-designated tuning parameters and the tuning algorithm modules arranged in the playing equipment and the sequence of the tuning algorithm modules to obtain a conversion file reflecting the corresponding relation between the tuning parameters and the tuning algorithm modules and the sequence of the tuning algorithm modules. The conversion file can comprise labels corresponding to the names of the tuning algorithm modules, the key value of each label is the tuning parameter of the corresponding tuning algorithm module, and the sequence of the labels represents the tuning sequence of the corresponding tuning algorithm modules.
The format conversion processing is performed on the tuning parameters, and the bin file of the tuning parameters may be converted into a JSON file, or may be converted into an XML file.
In one example, the conversion file may be a JSON file, and the contents of the JSON file may be as follows: "threshold _ low": 38, "ratio _ low":100, "knee _ low":0, "makeup _ low":3, 1. The "thres _ low", "ratio _ low", "knee _ low", and "makeup _ low" are labels corresponding to the tuning algorithm modules, and may be names of the corresponding tuning algorithm modules. -38 is the tuning parameter of the tuning algorithm module corresponding to the label "thres _ low"; 100 is a tuning parameter of a tuning algorithm module corresponding to the label "thres _ low"; 0 is a tuning parameter of the tuning algorithm module corresponding to the label "knee _ low"; and 3,1 is the tuning parameter of the tuning algorithm module corresponding to the label 'makeup _ low'. "thres _ low", "ratio _ low", "knee _ low", "makeup _ low" characterize the tuning sequence of the corresponding tuning algorithm module. The tuning algorithm modules corresponding to the "thres _ low", "ratio _ low", "knee _ low", and "makeup _ low" may perform tuning processing on the input audio signals in sequence, and then output the audio signals to sound production components such as speakers for playing.
If the tuning parameters of any tuning algorithm module need to be modified, the key values of the labels corresponding to the tuning algorithm module can be modified. Moreover, addition and deletion of the tuning parameters can also be realized.
The order of the labels and their key values can be adjusted if modifications to the tuning sequence are required. For example, the file content is converted into: "threshold _ low": 38, "ratio _ low":100, "knee _ low":0, "makeup _ low":3, 1. The tuning sequence at this time is "thres _ low", "ratio _ low", "knee _ low", and "makeup _ low". If the tuning sequence needs to be changed to "knee _ low", "thres _ low", "makeup _ low", or "ratio _ low", then the sequence of the corresponding labels and key values may be adjusted in the content of the conversion file to change to: "knee _ low":0, "" thres _ low ": 38," makeup _ low ":3,1," ratio _ low ": 100.
The obtained conversion file can be directly sent to the playing device, or can be transmitted to the playing device in a wired or wireless manner when receiving the operation of transmitting the conversion file.
The operation of transferring the converted file may be triggered by a developer or a playback device.
The format conversion processing is carried out on the tuning parameters to form conversion files, so that the tuning parameters and the tuning sequence corresponding to each tuning algorithm module can be more visually indicated. The byte number and the tuning sequence of the tuning parameters corresponding to each tuning algorithm module are not required to be preset in the tuning algorithm. Therefore, when the tuning parameters and the tuning sequence of any one tuning algorithm module are modified, the tuning algorithm does not need to be modified at the same time. Therefore, the process of modifying the tuning parameters and/or the tuning sequence is simpler and is easy to realize. Moreover, the workload of developers can be reduced, and the development cost can be reduced.
In one example, the method may further include step S7200: and encrypting the converted file according to a preset encryption algorithm.
Since the conversion file easily leaks the algorithm details of the tuning algorithm module and is easily reversely deduced out of the algorithm frame, the algorithm of the tuning algorithm module is cracked, and therefore the conversion file can be encrypted in the embodiment.
The Encryption Algorithm may be any one or more of DES (Data Encryption Standard, symmetric Algorithm), 3DES (triple DES), RC2 and RC4 (symmetric Algorithm), IDEA (International Data Encryption Algorithm ), RSA (asymmetric Algorithm), AES (Advanced Encryption Standard, symmetric Algorithm of Advanced Encryption Standard).
In one example, the method may further include the following steps S7300-S7400:
step S7300, acquiring an identifier of a pre-authorized playback device as an authorized identifier.
The identification code is used to uniquely identify the playback device, and may be, for example, a MAC address or a serial number of the playback device.
The authorized identification code may be an identification code of each pre-authorized playback device, or may be a range of identification codes of a plurality of pre-authorized playback devices.
The authorized identification code may be pre-stored in the server, or may be input into the server by the developer during the execution of step S7300.
Step S7400, format conversion is performed on the authorization identification code to a conversion file, so as to allow the playing device that obtains the conversion file to perform authorization verification.
Specifically, by storing the result of the format conversion processing of the authorization identification code in the conversion file, the playing device that acquires the conversion file can compare the identification code of the playing device with the authorization identification code stored in the conversion file, so as to verify whether the playing device that acquires the conversion file is authorized in advance.
In this way, the tuning parameters can be prevented from being used by unauthorized playback devices.

Those skilled in the art will appreciate that the server 800 may be implemented in a variety of ways. For example, the server 800 may be implemented by an instruction configuration processor. For example, the server 800 may be implemented by storing instructions in ROM and reading the instructions from ROM into a programmable device when the device is started.
