Display a color for each audio file?

[M22878]

I have this little program I made that randomly plays audio files. Does anyone know the easiest way to display a full-screen hex background color in the terminal for each sound file that plays? I want a specific background color attached to each file, so that the color is displayed every time the file plays. I want the terminal just one solid color, no text or anything else.

#include <iostream>
#include <windows.h>
#include <mmsystem.h>
#include <string.h>
#include <stdio.h>
#include <vector>
#include <random>
#include <algorithm>

using namespace std;

int main() {
    string e2 = "e2.wav";
    string a2 = "a2.wav";
    string d3 = "d3.wav";
    string g3 = "g3.wav";
    string b3 = "b3.wav";
    string e4 = "e4.wav";
    auto ints = vector<string> { "e2.wav", "a2.wav", "d3.wav", "g3.wav", "b3.wav", "e4.wav" };

    auto rng = default_random_engine {};
    while ( true ) {
    shuffle(ints.begin(), ints.end(), rng);

    for (auto i : ints) {
        PlaySound((LPCTSTR) i.c_str(), NULL, SND_SYNC);
    }
}
}

But your choice of colours is somewhat limited.

But you might be able to synthesis some other colours by dithering f/g and b/g with

U+2591 ░ Light shade
U+2592 ▒ Medium shade
U+2593 ▓ Dark shade

As for picking colours from filenames, perhaps a hash

@M22878,

IMO it might be easier to create a bare-bones Win32 API window, changing the client area's background color is easy vs. doing it in a command prompt console window.

Especially since your app isn't taking any input from the user. Just launch and listen.

@Furry Guy Okay, I will try that. But how do I assign each color to an audio file? Would I do that with a loop of some kind? Like, if g3.wav then background color is #FF0000 or something like that?

You have a list of WAV files to play, you create a list of the colors you want.

Best I can suggest is find some tutorials that will step you through the basics of Win32 API programming.

theForger's may be old, but it still will give you the basics.

If you want the assignment of colour to file to be done inside your C++ code, I'd use a std::map, using the filenames as keys, as the colours as values. Then, then you display a particular filename, you can easily obtain the appropriate colour from the map.
