Tools - Frequency Analysis (FFT and TFFT)
http://help.nchsoftware.com/help/en/wavepad/win/frequencyanalysis.html
This tool calculates an FFT analysis over time (TFFT), and uses color to display the intensities of the spectral information. To use it, select an area of the audio waveform you would like to analyze and select Tools -> Temporal Frequency Analysis. In the window that opens, you should see a graph displayed, known as the TFFT graph.

Advanced Audio Analysis Features. Perform a spectral analysis of audio at any one point in time, or across an entire duration. FFT has ability to zoom in on either x-axis or y-axis to see graph in more detail. TFFT has zoom ability as well as a color intensity specifier to choose the intensity at which colors are represented in the graph.

Although .wav is widely used when audio data analysis is concerned. Once you have successfully installed and imported libROSA in your jupyter notebook. You can read a given audio file by simply passing the file_path to librosa.load() function. librosa.load() —> function returns two things — 1. An array of amplitudes. 2. Sampling rate.
FFT - NTi Audio

The "Fast Fourier Transform" (FFT) is an important measurement method in science of audio and acoustics measurement. It converts a signal into individual spectral components and thereby provides frequency information about the signal. FFTs are used for fault analysis, quality control, and condition monitoring of machines or systems. This article explains how an FFT works, the …

FFT is a high-resolution audio analysis tool available as an in-app purchase in AudioTools. It uses the Fast Fourier Transform (see below) to analyze incoming audio, and displays a very detailed graph of amplitude vs. frequency. NOTE: This information applies to the FFT module available within AudioTools.

FFT Scaling for Noise - Audio Precision
https://www.ap.com/technical-library/fft-scaling-for-noise/
FFT Scaling for Noise. In Audio Precision analyzers, FFT spectra are scaled so that the amplitude axis gives the correct reading for discrete tones. This makes sense, because most often we are characterizing the performance of a DUT using sine waves.The amplitude axis, however, cannot be used to indicate the level of a spectrally non-discrete ...
numpy - ifft(fft(audio)) is just noise - Stack Overflow

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 ...
