Audio-to-Image and Image-to-Audio Transformation - DCT | IDCT

This code demonstrates a process of transforming audio signals into images using the Discrete Cosine Transform (DCT) and then reconstructing the audio signals from the images using the Inverse DCT ...

idct normalization unexpected? #3677

Is there interest in changing this behavior for scipy.fft? I think that it's an obvious inconsistency with the other FFT functions. It's also worth noting that FFTW doesn't do any normalisation for ...
