WebAdding FFT using the FFTW3 library to the Qt audio input program. This program is based upon the earlier Audio input using Qt and QAudioInput text and adds a second QCustomPlot that will be displaying the discrete Fourier transform (DFT) of the audio in a 2 second sliding window. To compute the DFT, the FFTW3 library will be used. WebMay 30, 2024 · Arm recognizes that we and our industry have used language that can be offensive.
