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 ...
FFT and IFFT of audio signal - MathWorks
https://www.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.
Frequency Domain Audio Synthesis – With IFFT and ...

What is the IFFT? Audio samples are considered samples in the “time domain”. If you instead describe sound based on what frequencies they contain, what amplitudes they are at, and what phase (angle offset) the sinusoid wave starts at, what you have is samples in the “frequency domain”.

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
Real time fft/ifft processing - Signal Processing Stack ...
https://dsp.stackexchange.com/questions/22493/real-time-fft-ifft-processing
when manipulating a live stream of audio data in the frequency domain, I've heard you need to do fft / ifft in small chunks, say 256 samples at a time. I've also heard you need to somehow employ a window function but I'm not sure the details on that.
