I recorded the video and brought it in to the video editor, then cut it all up and exported each of the sound effects separately as .wav sounds. Something I noticed is that the camera picks up a lot of audio noise. I turned off all electrical equipment to lower this but it seems to pick up high pitched noises regardless. To combat this I have imported all of the .wav sound files in to an external audio editing program, Audacity, and did 2 things. The first thing was to remove the noise, and the second was to export it as an MP3, which is a very compatible file type.
To remove the noise I opened the sound file in Audacity and selected Noise Removal under Effects.
You then have to select a sample of the noise that needs to be removed. Luckily I left some silence before and after each sound which was filled by noise so I was able to get a good selection. With the noise sample selected I click 'Get Noise Profile'. You can then adjust the slider for how much of it you want to remove. The noise is present even during the main sound, so the more you remove it, the more the sound is going to be effected and in some cases this really distorts the audio. Once I had refined it to sound as best as it could I clicked the remove noise button and was left with my sound, noise free.
You can see the difference in the waveforms:
I made a short video demonstrating the difference this has made to the quality of my sounds:
(I can't get the full video to upload, it cuts it off after 20 seconds, but you get the idea.)
