Sprint 4 CAGD 495

 For this sprint, I was struggling to create Whoosh sound effect.
When I began that, I thought that it won't be Whoosh sound because the card described just "Fireball sound". That's one of the reason why I took a long time. Secondly, I was thinking that I cannot use free sound source because I was said to do myself. I noticed that I can use free sources when I was given some free sources from a manager 2 days ago.

I used free audio sources from Sonniss, SE and Ambient sounds for movie, video, and game creation. This free resources were distributed as free in 2020, I downloaded then. According to the license pdf, I have already checked that it is fine to use them as our project.

Since here, I'll talk about my work details AFTER using free resouce.

This is original Whoosh sound


I used this sound and created sound effect for shooting fireball sound.
My main goal was to make SE as "loop-able".
To proceed this goal, there are several processes.

1. Not to be hard patterned
2. Slice in 2 and exchange the order
3. Delete border by "Cross fade"


I was working on Audacity.
It is not finished audacity project, but whole process is generally same.
First, I clipped area which I want to loop.
Second, I made an extra audio track to avoid hard patterned sound.
In my other recent audacity project, I created 2 other audio tracks.
I noticed that the audio clip will be natural when it's looped if I used many audio track.
Before duplicating the audio clip, it is necessary to attach "fade out" and "fade in" for cross fade.
Audio will not sound like CHOPPED when you use Cross fade.

After creating natural continued clip, I mix them and separate in 2 and switch the order.
At this time, there are 2 ways to avoid chopped, make connection point on 0 volume, or cross fade.

I used cross fade for this time, but I sometimes do first choice, so it depends on the case.

If you've done that, you'll get the loop-able audio clip.

This is my final audio clip.

This is not first audio project, but that was challenging work for me.
I think this work will be helpful in the next sprint.

Sprint 2 CAGD 495

  I was working on creating SE. I used SWave, old and free software which was created by Japanese, so it's displaying Japanese texts on each tab. I created sound with changing the shape of wave, especially changing the shape of each cycle, pitch shift, and volume. There are several track and I can mix them up to one sound effect. After that, I edited it in Wondershare Filmora. I removed noise, edited with quick equalizer tool, and added filter,  I made second dig sound with recording real sound and editing it. Jumping sound Digging sound Collecting sound Select menu I was also working on the placing props in Unity scene and general mapping of collective items This placement is just temporal for the prototype, so I'll fix them later. I focused on the LOD when I placed them.  There is no low poly model (according to a producer, she does not plan to make it), so I edited vanishing distance of objects.

Sprint 5 CAGD 495

 For this sprint, I created 2 short loop sounds and 1 long loop sound. I took 1 week for creating a below audio. General process is same as a previous work of Whoosh, but I combined 2 audio sources, twinkle and wind sound. Icy spell sound In other week, I made Shadow spell sound and river stream sound Shadow spell sound River stream sound I left same explanation on my card, but I'll leave it here too. I was thinking that the audio source will be stick on the particle object and loopable because the audio will be back to the beginning when player fires the spell in short span. If the other sound is triggered during a first sound is playing, a sound will be unnatural. To avoid this, I thought an audio source will be attached in the particle prefab and is not involved in the other spell. The audio sounds differently if I created a completed whole sound track of the spell. If loopable, sound volume will decrease by spatial sound and sounds natural. I was also working on the creating o

Game Scene Final Project Post

  Final Post This project is “Animal Crossing track in Mario Kart 8”.  For this project, I was joining the final project as 3D modeler, texture artist, UI designer, programmer, VFX artist, and Audio environment designer. Through this project, I was always focusing on the exporting format. I focused on exporting the fbx file with triangulated and mesh combined. When I shared my work, I uploaded the Unity package with prefabs of textured 3D objects to make importing easier. I think I did many various things in this project. I was especially working hard on VFX because I only had a short experience of designing particle systems. I studied a particle system in Unity for this project and succeeded in creating good VFXs. When I created spark particles, I referred to an online tutorial. However, when I created a boost particle, I made an original particle and I believe that the spark tutorial was helpful to understand the particle system.  The other thing I challenged is a scrolling textu
