Audio Scrambler code to create unintelligent audio

The code i created is below

stars = audioread('stars.mp3');

Mono = (stars(:,1)+stars(:,2))/2;

fs = 44100;

frame_duration = 0.1;

frame_len = frame_duration*fs;

N = length(Mono);

num_frames = floor(N/frame_len);

frames = cell(num_frames,1);

   for k = 1 : num_frames
      frames{k} = Mono( (k-1)*frame_len + 1 : frame_len*k);
   end

scramble = [(frames{4});(frames{6});(frames{5});(frames{1});(frames{3});(frames{2});(frames{7});(frames{8});(frames{9});(frames{10});
      (frames{14});(frames{15});(frames{16});(frames{11});(frames{12});(frames{13});(frames{17});(frames{18});(frames{19});(frames{20});
    (frames{24});(frames{25});(frames{26});(frames{21});(frames{22});(frames{23});(frames{27});(frames{28});(frames{29});(frames{30});
    (frames{34});(frames{35});(frames{36});(frames{31});(frames{32});(frames{33});(frames{37});(frames{38});(frames{39});(frames{40});
    (frames{44});(frames{45});(frames{46});(frames{41});(frames{42});(frames{43});(frames{47});(frames{48});(frames{49});(frames{50});
    (frames{54});(frames{55});(frames{56});(frames{51});(frames{52});(frames{53});(frames{57});(frames{58});(frames{59});(frames{60});
    (frames{64});(frames{65});(frames{66});(frames{61});(frames{62});(frames{63});(frames{67});(frames{68});(frames{69});(frames{70});
    (frames{74});(frames{75});(frames{76});(frames{71});(frames{72});(frames{73});(frames{77});(frames{78});(frames{79});(frames{80});
    (frames{84});(frames{85});(frames{86});(frames{81});(frames{82});(frames{83});(frames{87});(frames{88});(frames{89});(frames{90});
    (frames{94});(frames{95});(frames{96});(frames{91});(frames{92});(frames{93});(frames{97});(frames{98});(frames{99});(frames{100});
    (frames{104});(frames{105});(frames{106});(frames{101});(frames{102});(frames{103});(frames{107})];

sound(scramble,44100)

the code works fine but the thing is i want to give the frames an order to skip the typing of the order of the scramble, Do you think i can use a for loop or something to order it properly so that i can reorder it easily to get the original signal from my scramble audio?

Please help,

Thanks

Thanks.

order = [4, 6, 5, 1, 3, 2, 7, 8, 9, ....];
scamble = vertcat( frames{order} );

Thanks a lot, If i want to use with the random generator how can i do that?
