Do you need to record something, but the microphone included into your computer makes the sound quality sound horrible? Or do you want to test a cheap external mic before buying your own?
Here is a quick fix: a Logitech USB microphone! Just plug in and record what ever you want. Hyper easy to use. The microphone filters the (constant) background noise extremely well: the fan of my own laptop makes horrible noise, but when I use this mic, it makes almost all the noise to vanish!
I warmly recommend downloading a free recording program named Audacity, if you want to hone the sound clip even clearer.
The mic is located in Otaniemi, and I can easily borrow it upon request. I can also give some tips for improving the sound quality.
