            When I get your question right, you want to reconstruct the real/imaginary spectrum from your magnitude values. You will need the phase component for that, then its all simple complex number arithmetic. You should be aware that the output of an STFT is an array of complex numbers, and the amplitude is the absulute value of each number, while the phase is the angle of each number

            Here´s an example of a time-domain signal transformed to magnitude/phase and back without modifying it:

            np.argmax gives you the index of the maximum element in the Fourier frequency, not the actual frequency. The relation to obtain the frequency from the index is frequency = index*rate/len(Fourier). So, applying this in your case should give you the desired frequency:

            The failed prop type errors are due to not passing the correct props to the Sound component.

            If you take a look at the README, you can see that the values you are assigning to ref.current can be passed as props to the component:

            IDirectMusicPerformance8 - MIDI only, or WAV?
            Asked 2021-Jun-07 at 19:14

            I'm trying to work with an old version of DirectX (8.1) and I'm finding the documentation more than a little confusing. It feels like the IDirectMusicPerformance8 interface is for MIDI playback, as it has various MIDI-related methods on it, but various parts of the documentation suggest that it can be used to play back WAV data as well. For instance, the tutorial says that you call InitAudio on the performance, and it states "Wave files require only a single performance channel, and MIDI files require up to 16".

            So is it for MIDI or can it be used for WAV?

            If it can be used for WAV, I'm even more stumped, because I'm initializing it, running performance->PlaySegment(segment, 0, 0, NULL), getting a success response, but the audio is silent.

            Answered 2021-Jun-07 at 19:14

            OK, I figured it out. Apparently I had been using IDirectMusicPerformance instead of IDirectMusicPerformance8, which I guess is some kind of old compatibility thing that is missing various new DirectX 8.1 methods. Once I switched to that (along with the associated '8' versions of the loader and segment interfaces), used their new InitAudio and LoadObjectFromFile methods, called segment->Download(performance) before playing, then played with the new PlaySegmentEx method, it worked and played the WAV.

            Lately @MrWhite gave us another, better and simple solution - just add DirectoryIndex index.html to .htaccess file will do the same.

            From the beginning I wrote that DirectoryIndex is working but NO! It seems it's working when you try prerender.io, but in reality it was showing website like this:

            and I had to remove it. So it was not issue with .htaccess file, it was coming from the server.

            What I did was I went into WHM->Apache Configurations->DirectoryIndex Priority and I saw this list

            and yes that was it!

            To fix I just moved index.html to the very top second comes index.html.var and after rest of them.

            I don't know what index.html.var is for, but I did not risk just to remove it. Hope it helps someone who struggled as me.
