`Analysis`

The playback speed is too high.
So lets reduce the speed.

Now the speed is fine.
But the lyrics is not recognizible.
So let's try to reverse it now.
We may or may not get anything even if we reverse.
But let's try to do it.

Now if we play the audio, we shall hear the numbers and text.
This is where the audio should be listened carefully.
Initially I got 3b27641fc580.
But this is not the flag.
Some texts look like texts, but it's actually Numbers.
Reference is in YouTube.

After refering this I understood that H --> eit ( 8 ).
