Apparently I made this for my animation which supposedly a parody of sitcom shows...and since I find the laugh tracks in the internet a little too "cliche" (and I've used it a bunch of times in my videos already), I decided to make my own.
So, all I did was record my voice doing different kinds of laughing (mostly giggles or chuckles since I somehow can't force out a fake laughter by the time of recording) in my normal and falsetto voice for at least 1 minute. Then I edited it all out in Audacity. I also resampled older recordings of my fake laughters and pitched down the duplicated tracks so that it would sound "bigger".
Please credit me as LittleRainySeasons if you're going to use them. Thanks :)
