The following patch helps mess around with audio files by adding time delays, shifting pitch and adding feedback. This, of course, resulted in a lot of interesting experimentation.

The first video shows how the ‘chipmunk’ voice filter can be achieved. The pitch shift for heavy voices generally worked with 1.8x transposition factor and for lighter voices 1.4x usually gave a good chipmunk voice. The songs used in this video are Pillowtalk by Zayn and Hello by Adele. While experimenting, I also found a time delay from 50ms to 200ms usually complemented the original. You can see me messing around with feedback as well.

While experimenting with the pitch shift, I remembered a song, ‘Cinema’ by Skrillex, which had a kid-like voice before the dubstep drop. I decided to find out what the voice could have actually sounded like before it was modified and here it is. The first one is the original, followed by what I thought would be the actual voice-

Continuing on the path of exploration, I encountered a slight effect of reverb or concert while using feedback. I found out how the effect of slight echos are created-

In the end, I just had fun with the Iphone ringtone, creating drumbeats(may need to increase volume), really cool sounds and some other effects-
