Method adds module 53, for respectively in described Dolby COPP equipment and described DTS COPP equipment
Add described Dolby post-processing algorithm and described DTS post-processing algorithm；And parsing module 54, use
In the Dolby post-processing algorithm added and DTS post-processing algorithm are resolved.
Preferably, described configuration file modified module 51 can utilize the audio alignment that Qualcomm provides
Described configuration file revised by instrument, i.e. QACT.By amendment configuration file so that utilize high pass to put down
The COPP of Dolby and DTS it is added on the display interface of the terminal (such as, mobile phone) of platform system
Menu option, so that Dolby post-processing algorithm and DTS post-processing algorithm can be added to
In high-pass platform system.And by the configuration file modified module 51 amendment to configuration file, with regard to energy
Enough making cannot be by the most integrated in integration phase Dolby post-processing algorithm and DTS post-processing algorithm
Problem has been resolved.
It addition, the Dolby COPP equipment that equipment creation module 52 is created is located after can running Dolby
Adjustment method；The DTS COPP equipment that equipment creation module 52 is created can run DTS post processing and calculate
Method.Wherein, Fig. 4 shows establishment COPP equipment (such as, Dolby COPP equipment and DTS COPP
Equipment) Operation interface diagram.
Preferably, described parsing module 54 can by the parsing of DSP file structure to being added
Dolby post-processing algorithm and DTS post-processing algorithm resolve, so, the Dolby added
Post-processing algorithm and DTS post-processing algorithm just can be identified for can using in high-pass platform system
Suitably post-processing algorithm carries out post processing to audio signal.Such as, described parsing module 54 can lead to
Cross the parsing to described DSP file structure to identify the mark of described Dolby post-processing algorithm and described
The mark of DTS post-processing algorithm, so locates after employing is integrated with Dolby post processing and DTS simultaneously
The high-pass platform system of reason just can be by the mark of post-processing algorithm when audio signal carries out post processing
Select Dolby post-processing algorithm or DTS post-processing algorithm.
