FFT and IFFT of audio signal - la.mathworks.com
https://la.mathworks.com/matlabcentral/answers/328481-fft-and-ifft-of-audio-signal
What does class() of the audio data show? If it is one of the integer classes like uint16, then the fft will be type double and the ifft of that would be type double, not the original data type. When you have data of type double that is outside of the range -1 to +1 then if you use one of the audio file writers then the data will be clipped.
numpy - ifft(fft(audio)) is just noise - Stack Overflow
https://stackoverflow.com/questions/14574208/ifftfftaudio-is-just-noise
whether i just nest them ( iff (fft (audio))) or try window-by-window ( window the audio, do the fft, do the ifft, then invert the window, replacing zero with eps, then merge the samples back (trying abs here and there in the pipelines)) i get only noise. i know the ifft is only inverse to the fft with infinite precision arithmetic, infinitely ...

Help with Audio Signal noise removing using FFT and IFFT ...
https://dsp.stackexchange.com/questions/66101/help-with-audio-signal-noise-removing-using-fft-and-ifft-in-matlab
I dont understand why my modified fft of a audio signal returns complex values after ifft. I modified my signal by zeroing out all the unnecessary freq. FFT: Fast fourier transfrom. IFFT: Inverse fast fourier transform. Heres the matlab code and graph
Frequency Domain Audio Synthesis – With IFFT and ...

Even with the “Fast Fourier Transform” (FFT), that is a huge number of bins and would take a long time to calculate. One way to deal with this would be to have fewer bins than audio samples that you want to end up with, use IFFT to generate the audio samples, and then use interpolation to get the audio samples between the ones generated by ...

Proper FFT / IFFT missing · Issue #248 · WebAudio/web ...

taking the FFT output, manipulating it in some way, and sending it out to an IFFT block to get back an audio signal. At that point, the ScriptProcessorNode could do the FFT/IFFT itself, perhaps somewhat more slowly. And don't forget that an FFT block can do the IFFT if you feed it the conjugate of the transformed data. More or less.
audio - Accuracy of IFFT(FFT(X)) unit transformation ...
https://dsp.stackexchange.com/questions/27764/accuracy-of-ifftfftx-unit-transformation
To do that, I need to get a handle on the fundamental accuracy of the FFT() and IFFT() algorithms available. My idea is to look at IFFT(FFT(X)) which should be a unit transformation. I want to get the maximum difference between the input and output data down below the region of 1 part in 10^8 or even 10^9.
