Geocache Description:


The cache is not at the published coordinates. Thanks to Wandafree for making the container. Bring tweezers.

The real coordinates are: N54° **.*(*-4)* W000° **.(*-1)**

The missing digits are contained somehow in an audio file linked below the next paragraph. It is not necessary to download the file to solve the puzzle, but it might be convenient. In case you do, a disclaimer:

Alert: You are about to download a file that contains details needed to find this geocache. As the geocache owner, I ensure that this file is safe to download. It has not been checked by Geocaching HQ or by the reviewer for possible malicious content. Download this file at your own risk.
Cache Audio File

It is not necessary to sign up to Dropbox to listen to or download the file; if you are prompted to do so, you can just close the sub-window. You can adjust the playback speed with the cog icon at the bottom. Of course, downloading it and opening it in a decent audio editor will give you the most options for visually inspecting and playing the audio at your desired speed.

To save you counting, a note is played 371 times. This number has a special property that will help you correctly interpret the audio.
Also, to save more time once you figure out the significance of this audio, I will leave you with: wide, not tall.


OPTIONAL
When you figure out what to do with the audio, if you want to save yourself time and effort, you may message me to tell me precisely what you would otherwise do with it. If you are correct, I will then reply with the result as if you had carried out the steps yourself. This is not at all necessary to solve the puzzle, but I am happy to do this nonetheless. Do not consider this cheating. It won't make the puzzle any easier; just quicker.


As with any puzzle of mine, feel free to message me if you want help with any aspect of this puzzle.

Congratulations to marions27 and cabbagepatchkids for FTF.
