Research and Development of APP and HCI based on Audio Data Feature Extraction

Research and development of the string music auxiliary training APP based on audio data feature extraction is presented in this article. Mobile platform-based APP testing mainly considers the APP installation and uninstallation testing, functional testing, UI testing, core compatibility testing, cross-event testing, security testing. This article combines the novel framework design pattern to construct the novel methodologies. A core hierarchical two-step segmentation algorithm is used to segment the audio stream into audio units with large differences between the segments and small differences within segments. The experiment has proven the performance of the proposed framework.
