Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.In addition, technical characteristic involved in each embodiment of invention described below is only
Not constituting a conflict with each other can be combined with each other.
In the embodiment of the present invention one, as shown in Figure 1, the present invention provides a kind of program sum numbers for saving audio processing
According to the method in space, comprising the following steps:
S1, audio data is obtained；
S2, audio format is obtained according to audio data, parsing is carried out according to the audio format and obtains the audio data
Corresponding decoding table；
S3, the corresponding decoding table of the audio data is only loaded to memory progress audio processing.
Between the step S1 and step S2, further includes: initialize the audio data.
In a specific embodiment of the present invention, initialization space can be multiplexed when carrying out audio processing.
It in a specific embodiment of the present invention, can also include: that release initializes the audio before the step S3
Data the space occupied.I.e. in the present invention, when handling audio data, directly initialization memory space can be answered
It writes, can also first discharge the initialization space, then carry out audio data processing.
In a specific embodiment of the present invention, by taking WMA is decoded as an example.Audio data is obtained first, is obtained according to audio data
Obtaining audio format is WMA, and a complete WMA decoding needs 6 huffman tables, and the title of these tables is " Huffman- respectively
RLC-16 ", " Huffman-RLC-44Q " and " Huffman-RLC-44O " divide 3 groups, and every song only chooses one group of table, often
Group has 2 tables, can be used for solving monophonic per a wherein table, L channel, right channel, merges sound channel, another table is used for guards escorting prisoners
Divide sound channel.During initialization, parsing can be carried out according to audio format and obtains the corresponding decoding table of the audio data, i.e.,
It can determine that the corresponding decoding table of the audio data is Huffman-RLC-16, Huffman-RLC-44Q, Huffman-RLC-
44O which, so as to only load this table to memory, other tables do not need to load, and can save always disappear in this way
The memory and resources of chip of consumption.
The code of initialization also occupies certain memory simultaneously, after initialization, due in decoding process, needing to export
Decoded result or decoded audio PCM data, the occupied sky of initial code before these data can be directly used
Between, total code consumption can be saved.
In the embodiment of the present invention two, as shown in Fig. 2, the present invention provides a kind of program sum numbers for saving audio processing
According to the device in space, comprising:
Data acquisition module 1, for obtaining audio data；
Decoding table obtains module 2, for obtaining audio format according to audio data, is parsed according to the audio format
Obtain the corresponding decoding table of the audio data；
Data loading module 3 carries out audio processing to memory for only loading the corresponding decoding table of the audio data.
The device of the program and data space for saving audio processing further includes initialization module 4, for initializing
State audio data.
The device of the program and data space for saving audio processing further includes Multiplexing module 5, for carrying out audio
Multiplexing initialization space when processing.
The device of the program and data space for saving audio processing can also include Free up Memory device, for discharging
Initialize described audio data the space occupied.
Wherein, the output end of the data acquisition module 1 connects the input terminal of the initialization module 4, the initialization
First output end of module 4 connects the input terminal that the decoding table obtains module 2, and the decoding table obtains the output end of module 2
The input terminal of the data loading module 3 is connected, the output end of the data loading module 3 connects the of the Multiplexing module 5
One input terminal, the second output terminal of the initialization module 4 connect the second input terminal of the Multiplexing module 5.
It is described the present invention provides a kind of electronic equipment, including memory and processor in the embodiment of the present invention three
The method that processor is used to execute the program and data space for saving audio processing.
In the embodiment of the present invention four, the present invention provides a kind of computer readable storage medium, the computer can
It reads storage medium and is stored with computer program, the computer program realizes the saving audio processing when being executed by processor
The step of method of program and data space.
Because audio processing generally requires certain initialization and model selection and parameter configuration, then execute again main
Flow processing, therefore, the present invention are mainly to utilize the characteristic of audio processing, some resources are multiplexed, to reach saving audio processing
Total resources occupy.The occupied space of the code wherein initialized can release, as the processing of subsequent main flow
Caching.In addition, decoding for WMA, have 3 huffman tables it can be selected that primary 3 tables of load, will unusual occupied space, but
If determining which the table of song selection is after initialization, then only needing to load this huffman table, then can save
It saves and loads other dead codes.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
