|Title:||DESC9115 Final Proposal|
|Abstract:||Because of the good performance of vocoder and the potential value of time and pitch shifting, this paper attempts to create a phase vocoder APP through MATLAB, which is used for teaching or research in the initial stage. The main expectation of this APP can achieve sound, Window type, Spectrogram and Waveform real-time contrast and the diagram (or sound) fast switching. Later stages can be developed as a stand-alone vocoder, or as a Third-party plug-in. Hence, there are three problems in here. Firstly, what is the principle of the phase vocoder? Then, how to implement it in MATLAB? Finally, how to integrate these function into the GUI interface. The results show that GUI interface as expected, waveform, spectrogram, sound and window functions can appear simultaneously, and switching speed as expected. The drawback is that the overall design of the interface is not very intelligent, so it needs to be improved in the future.|
