Every project contains the little boring jobs that you have to do before you can get down to the exciting stuff. Today I’ve been editing a sound recording I made of my clock ticking.
First it was too quiet so I used Audacity to amplify it, but then all the background noises were amplified too and there was a lot of hissing in the background. Audacity has a filter for removing background noise – it doesn’t always give great results (because sound is a very complicated thing) but it has cleaned it up enough for what I want, and it’s still recognisable as a ticking sound.
In the video I am removing the last bits of background noise that the programme didn’t get, which was actually caused by me moving as I was doing the recording! The blue blobs you can see on the screen are the where the ticks are, and I’ve zoomed right in so I can highlight the areas between each one where there’s a bit of extra noise and then remove it.
A very boring job but it will make for a much nicer piece of audio in the end!
