Tools for Interactive Audio Signal Analysis based on Sliding DFT
This article describes an application the author developed in order to compare analysis and synthesis of musical audio signals through Short Time Fourier transform (STFT), Constant Q and Sliding Discrete Fourier Transform (SDFT). This software is the basis for applications of SDFT and Constant Q to other consolidated synthesis techniques. By itself, it is a stand alone instrument for calculating and quickly comparing spectrum analysis and synthesis of musical signals. No expertise is required and it can for example be easily used by music composers without in depth knowledge of DSP processing tools.
