| Abstract: | In response to the problem that native Audio Effect framework of the Android system does not support 32-bit audio, a new Audio Effect framework was proposed by using the FFmpeg open source audio and video framework. The Butterworth part of its high-order audio parameter multi-band equalizer algorithm was used as the filter, and the algorithm was analyzed, verified and tested in application. Simulation and test results show that this method can improve the accuracy of equalizer and meet the design requirements. |
