I am using 2.0.5 and am making a simpsons story and am wondering how I would be able to make bart and homer’s voices within audacity
As far as I’m aware, the voices of Bart and Homer are recorded without any effects - it’s Dan Castellaneta (Homer) and Nancy Cartwright (Bart) doing a thing called “acting”. The only software I know of that can come close to ding that is “Lyrebird” https://www.descript.com/lyrebird-ai?source=lyrebird
Nancy Cartwright, a short American lady once reduced a Buckingham Palace guard to rubbish by walking up to him and turning into Bart Simpson.
The acting part is rough. Interpretation, swing, emphasis and tone. All difficult to put in an effect, even if you do get the pitch and volume right.
You have 2 options, really:
Hire someone who can do a good impression of those characters (there are some talented people out there who can more or less replicate character voices) and have the lines you want recorded.
Find isolated dialog for these characters (various video games were made based on the series and tools exist which can convert the sound files to something more standard, such as WAV) and chop together the lines. This is a last-resort option since it’s not easy and will take a ton of time. That, and it will sound odd if you don’t have a boatload of lines at your disposal…
