Having spent alot of time experimenting with a microphone I have come to the conclusion that capturing the actual sound of an environment is near impossible. Numerous times I have tried to record the sound of the sea, but among technical difficulties I found it was extremely difficult to capture sounds in the same way that the human ear does.
In this I realised that the best way to give the impression of the sound you are trying to record is to substitute the sound of other objects then master them. For the sound of the sea I managed to find something to recreate the sound of crashing waves in my bedroom by rustling a sleeping-bag. I then dubbed this over whitenoise to give some depth, and the result I have posted below:
