About DPS Profiles

The process of customizing the DPS algorithm for a particular device is called “tuning”.  To make this easier, the DPS Profile Creator connects to the DPS library to modify the audio processing parameters.  When customization is complete, the data set is exported to a “DPS profile”.

A DPS profile may be formatted differently depending on the platform.  This is a list the profile formats supported by the DPS Profile Creator:
