I DID NOT MAKE THIS, i simply am sharing where i got the tutorial from. dis was made by: Ghost2187875 on gamebanana. all credit goes to them IF THE TUTORIAL IS REMOVED (for some reason-) HERES WHAT IT SAYS: "Hi you might be wondering how to make Null's Voice. well heres a tutorial!

1. open up audacity and put your HZ to 8000 and make sure your Microhphone settings are MONO and record your voice

2. Follow these effects top to bottom Distortion (Soft Overdrive) Distortion 100, Make up Gain: 56 Put it 6 - 10 Times until its all filled up into a square

3. For glitch sounds you can just import raw data by going into File > Import > Raw Data. and make sure you are importing it as a GSM 6.10

And you are done! you should have a voice like Null!"

if you wanna just do eggmans/alfreds voice, I used the unedited version on youtube. it starts at 1:23.

I downloaded it using a ytmp3 site, went on audacity, clicked on "file", pressed "open", selected the audio, and then went into distrotion. DISTORITION IS LOCATED INSIDE OF EFFECTS. It is below "delay and reverb", and above "special". THE BEEPS HOWEVER, i manually added from the classic, via the wiki.
