1. On first hearing the “AccessCode.wav”, ([Download the audio clip here.](https://clyp.it/jr0neooz)) I had a hunch that this sound might be representing Morse Code in an audio format.
2. After scouring the internet for a while, I came across a site named - [Morse Code Adaptive Audio Decoder](https://morsecode.scphillips.com/labs/audio-decoder-adaptive/)
3. My assumption was correct. I uploaded the “.wav” file and the Adaptive Audio Decoder Site analysed the file to give the following output.

4. On submitting the following decoded message to the challenge, I was able to retrieve the Flag.
