摘要:
针对安卓系统原生Audio Effect 框架不支持32 bit 音频的问题，提出了采用FFmpeg 开源音视频框架自定义新的Audio Effect 框架。选用高阶音频参数多波段均衡器算法的巴特沃斯部分作为滤波，对该算法进行分析、验证和应用测试。仿真和测试结果显示，该方法可以提高均衡准确性，达到设计要求。
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.
