Project 1: Sound Dubbing & Sound Shaping

Project 1: Audio Dubbing
We were given a clip from the movie Munich (2005) where the sound is completely removed. This is because the task is for us to fill in audio through the use of sound effects and dubbing with voice lines for the characters. 



Fig 1.1 - Empty Audio Clip



Fig 1.2 - Sequence progression

After analyzing the scene, the starting sequence has a bunch of sound effects which is layered over one another such as the man walking on concrete, street ambience which is not shown on screen but important to add the feel of atmosphere to the clip, the sound of the car rolling was placed before it enters the scene as audio can be used to signal its arrival, the footsteps of the girl outside. These audio files are first obtained from websites such as Freesound, Pixabay or various smaller sound effect websites. Then they were arranged in the sequence presented above, with each attempt adding another layer over each sound effect to mold it to a realistic outcome matching with the clip that I was satisfied with. Tracks A1-A4 is used for voice lines dubbing, while tracks A3-A8 is used for layering sound effects and blending it well together. I made sure to time the audio track to follow extremely closely to the visuals displayed on the screen. 

These same analysis tactics were used throughout the audio dubbing project to find, place and edit the sound effects to be in the desired locations along the tracks.


Fig 1.3 - Sound levels

Some clips had their decibels increased to fix soft sound effects that are downloaded. A few attempts were made to test the output of the sound until it reaches the perfect level of audio I needed for the clip. In this case, I increased the sound level of the sound effect for the girl walking on a carpet.


Fig 1.4 - Pitch Shifter

The audio clip has a few characters speaking where voice lines are required. Thus, I recorded my own voice by saying that character's dialogue and imported it into the audio track. However, I need to change how my voice sounds to suit the characters. That's where pitch shifter comes in, with this effect, I was able to create a deep sounding voice for the man, while a high pitch voice for the girl. This is possible by arranging the Semi-tones and Cents for the selected audio file. Lower Semi-tones and higher Cents leads to a deeper voice, while higher Semi-tones and low Cents leads to a high pitch voice. The same procedure was used to edit the voice for other characters in the clip through playing around with the number values of Semi-tones and Cents until I was satisfied with the voice. One thing I found difficult is that its hard to change the pitch of my voice to make it realistically sound like a girl as it still sounds funny after trying the pitch shifter.

Here is the final result of the Project 1's Audio Dubbing exercise.

Project 1: Sound Shaping
This exercise dives into the app of Audition and teaches us how to alter the effects from a sound clip to make it have different feel for it. The audio can be crisp and enhanced to sound like audio from a cinema, or it can sound soft and low quality like a voice from a telephone. 

The task is for us to edit a given audio clip while shaping its audio to fit these scenarios:
  1. Voice on phone call
  2. Voice coming from inside of closet
  3. Voice of toilet/bathroom
  4. Underground cave

Fig 2.1 - Parametric Equalizer

By using the Parametric Equalizer effect, the audio was edited to sound like a phone call by editing the wavelength of the effect.


Fig 2.2 - Convolution Reverb

Convolution reverb allowed me to tweak the settings from the presets to create the effect of being in a toilet. 


Fig 2.3 - Echo

After trying the effects from Parametric Equalizer and Reverb, I did not manage to find an echo effect for the cave that I was satisfied with so I decided to search on YouTube on how to create an echo in Audition. That's when I learnt the Echo effect, by editing the values of Echo Level and Successive Echo Equalization, I managed to create a echo that slowly dwindles as the clip goes on to mimic the echoes that can be produced in a cave.

Gameplay has some accessibility through allowing multiple options for movement by either using WASD or Arrow Keys. The sound effects fits smoothly with the visuals along with the background music fitting for the visual themes of the game, contrasting the enraging nature of the actual gameplay. About the gameplay, the initial level design is cool, slowly introducing more controls to help ease the player into the mode. However, having only 1 HP from terrain elements raised the difficulty of the game. It is as critical as avoiding any mistake from touching terrain elements, which ...

To understand websites better, we are tasked to analyze TWO websites from this link . A brief summary of analyzing 2 websites was written so we can take note and improve our understanding of the design,  layout, content, and functionality, strengths and weaknesses about websites. The websites I chose to analyze were Simply Chocolate and Torgerson Design Partners .  Here is my analysis for each website. Simply Chocolate Landing page looks clean and gives an easy introduction. The big white text is clear and readable but the smaller texts of white can be harder to see as the background is also of light color. The menu texts on the side are placed sideways, making it harder to read quickly or rep...
