A method and system for converting two-dimensional artwork into three-dimensional models. The disk body has two sides, an outer periphery, a central hole, multiple through holes and multiple curved grooves. The audio signal processing unit is utilized for determining a total number of audio channels corresponding to the individual audio interfaces and generating a first output audio signal with a first number of audio channels according to an input audio signal and the total number of audio channels when the audio signal processing apparatus is operated under a first operational mode. By thrust bearings attached in holes in the annular plate on body axial sides of the inertial mass body and by a journal bearing attached in a recessed groove in the inner periphery of the inertial mass body, the inertial mass body is supported both axial sides and radially and disposed for peripheral rotation in the sealed chamber. The content is stored in the second memory device and the memory device and the second memory device are configured to be removably coupled to a computing device. A report is provided to the client device based on the determination.
