The patch used for this audio visualization system is similar to the one made in class. As documented in the following Youtube video, you can see me experimenting with how different shapes react to a song. Later in the video, I decide to modify the helper patch into using the phases in the fft to modify the shapes. As you can see, it creates interesting patterns. The pattern seemed to be resembling consistent randomness. So I decided to compare it with the patterns that the shape creates with noise amplitudes. Turns out, it gives a similar effect but is more widely spaced(probably something to do with the magnitude of the values). Here is documentation followed by the main patch and helper patch.

The main patch-

Song used-

Kina- Can we kiss forever?

Patch used and modified upon- Meshy patch developed in class

When you are given a convolution patch and an infinite number of sounds, there is a lot you can explore. When I started exploring, I was expecting a lot of unique outcomes, which was true but didn’t sound as well as I would imagine. So I found the best 4 IRs. The first video shows me using Impulse Response recordings of popping a balloon in the elevator of Cohon Center, as well as the Morewood Multipurpose room(which had quite a lot of echo as you would see in the video in the second demonstration). The third demonstration shows me using the inbuilt sound ‘arctic.wav’. After experimenting with all the inbuilt sound files, this one sounded the best with the instrumental part of the song as we can observe in the video-

For the fourth IR, I tried out different songs to see what effects it would have. I tried one of my favorite song’s(Kina – Can we kiss forever?)  part with the climax as the IR. It turned out to create a really magical soothing sound if the volume is controlled well enough. However, the original song can barely be heard anymore. The way the song fades out is pretty clean. The first video is the IR recording used and the second video is the outcome.

Songs used-

Ed Sheeran- Shape of You

Kina- Can we kiss forever?

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-
