LECTURES
All lectures completed in Video Sound Production - Exercises

The mixing of the sound elements below creates an audio setting that supports the action and engages the spectators.
  1. Speech
    - Dialogue: Conversation between characters in the movie.
    - Voice Over: The voice of an unseen narrator speaking.

  2. Sound effects
    - Ambience: Audio refers to the background noise present at a given scene or location.
    - Hard or "Cut" Effects: Almost every sound we hear at the movies that isn't dialogue or music. E.g. sliding door opening and closing, footsteps, train moving on tracks, ambience in train etc.

  3. Music
    - Enhance the dramatic narrative and the emotional impact
Dubbing: or Automated Dialog Replacement (ADR), is the process of re-recording dialogue after the filming process to improve audio quality or reflect dialogue changes
Foley: Sound effects technique for synchronous effects or live effects. Named after Jack Foley, a sound editor at Universal Studios.

PROJECT 1: Audio Editing

Exercise 1: Sound Dubbing
In Exercise 1, we were tasked to do audio dubbing (speech and sound effects only, no music) to a muted clip from the movie "Munich". We will need to record the dialogues and find sound effects for the clip, then edit the audio to match the clip. 
  1. Watch the video on the Premiere Pro timeline
  2. List down each scene on a spreadsheet
  3. List out each sound effects for each scene
  4. Record voice with the phone, and search sound effects online.
  5. Place audio files on the timeline, and sync them with video.
Sound effects can be found online from:

Notes:
- Dialogue: Audio tracks 1-4 - one character one track (-6dB to -12dB)
  Hard Sound Effects: Audio track 5-7 (-6dB to -20dB)
  Ambience Sound: Audio track 8-10 (below -20dB)
- Edit voice from female to male, male to female, human to cute animal/adult to kid:
  Premiere Pro → Audio Effects → Pitch Shifter → Semi tones
- Do not include any music

Spreadsheet with Audio and Dialogue
We had to prepare a sheet with all the audio: sound effects found online and dialogue recordings. Below is Exhibit A and B of reasons I hate myself. I mainly got the sound effects from Pixabay and YouTube. The same sound effects are used in multiple scenes, so I just reused them.

Editing in Premiere Pro
Once all the audio was gathered, I placed the dialogue, hard sound effects and ambience together in Premiere Pro. Before doing so, I made a sequence with a timeline having 10 audio tracks. Throughout the editing process, I went back to find more audio as I realized some sound effects did not match the clip and some were missing.

I used the pitch shifter to change my voice, e.g. decreasing the semitone to get a female-to-male voice, as well as increasing the semitone to get the young kid's voice. The dialogue in scene 11, is spoken through a telephone. I edited the voice by applying Essential Sound presets - Dialogue: From the Telephone.

This is my first final version of the audio dubbing. Mr. Martin advised me to make the ambience louder and fade from indoor to outdoor ambience in one scene. I also forgot to add the fade-in and fade-out for the audio clips, so I went ahead and corrected it.

Exercise 2: Sound Shaping
In Exercise 2, we were tasked to do sound shaping, which includes recording our own audio and shaping it into the assigned sound effects listed below:
  1. Voice of phone call
  2. Voice coming from inside of the closet
  3. Voice of toilet/bathroom
  4. Underground cave
  5. Alien/ Orc voice
I recorded my own voice for over 5 seconds, then imported the audio into Adobe Audition. To start editing audio: create a Multitrack session → name and save it.

Sound Shaping in Adobe Audition
Phone Call Sound Effect
I used the parametric equaliser to edit the audio track (Effect rack → Filter & EQ → Parametric Equalizer). For a phone call effect, bring down BASS, TREBLE, and raise MID RANGE between 500Hz  to 2kHz.

Muffled (Voice From Inside the Closet) Sound Effect
This sound effect is also edited with Parametric Equaliser. A muffled sound is made by remaining BASS, bringing down TREBLE and raising MID RANGE to the top. 

During my first attempt, the voice did not sound muffled, I had no idea what I was doing wrong. From following this YouTube tutorial, I then realized I had to bring down the treble (high frequency) more.

Reverb Sound Effects
Reverb is sound in SPACE, an echo caused by the reflection of sound waves from a surface. (Create a new Multitrack → apply Reverb). 
  • Decay Time: Specifies how many milliseconds the reverb takes to decay 60 dB. Longer values give longer reverb tails.
  • Pre‑Delay Time: Specifies how many milliseconds the reverb takes to build to its maximum amplitude.
  • Perception: Simulates irregularities in the environment
  • Dry: To add subtle spaciousness, set the Dry percentage higher; to achieve a special effect, set the Dry percentage lower. 
  • Wet: To add subtle spaciousness to a track, keep the Wet percentage lower than the Dry percentage. 
Voice from Inside a Bathroom
From listening (eavesdropping) to feedback in tutorial class, I learned there should be an echo, hence the reverb, but it should not be too strong. A bathroom is usually small, which absorbs more sound therefore there is minimal echo.

Voice from an Underground Cave
I edited two audios for the underground cave sound effect. The first was just specifically using 'Reverb'.

I wanted to play around with more settings which is how I got the second sound shaping for the underground cave, which uses 'Convolution Reverb'. Following the below tutorial made the sound effect more realistic.

Alien/ Orc Voice
The last sound effect was quite challenging. In my mind, an "alien voice" can be anything as long as it does not sound human. I wanted the voice to be unrecognizable and distorted. At first, I tried to edit the voice by just using the pitch shifter, reverb and Parametric Equalizer, but that did not really do anything.

I shifted the pitch, adjusted the flanger and added reverb and distortion. It was more or less slapping any effect possible to make it sound strange, but still able to hear what was being said.

FEEDBACK
WEEK 4
Good work on the sound dubbing. It can be improved by making the ambience louder and fading from indoor to outdoor ambience in one scene. Add fade-in and fade-out for all audio. 



REFLECTION
Exercise 1: Audio Dubbing
The audio dubbing exercise gave me a better appreciation of the importance of sound and audio in a scene. Before this, I always thought what we see on the screen makes the whole scene, well... A SCENE. Now when I watch movies or TV shows I pay attention to how the audio is crucial to the experience, without it, it's just a silent film. Every sound effect from footsteps to wind blowing to a loud explosion contributes to the overall atmosphere. It requires lots of attention and patience to make the sound realistic: too loud of an ambience sound volume, not synchronized footsteps, and the wrong type of explosion sound, can more or less break the scene. I spent hours (and lots of storage space) finding the right sound effect and fine-tuning each audio clip to sync with the video. This exercise has given me a massive understanding and appreciation of the importance of sound effects in a scene. 

Exercise 2: Sound Shaping
With the second exercise, I spent more time focused and paying attention to how each audio sounds - little details like echos, pitch, etc. Using Adobe Auditon to try out different sound effects other than Parametric Equalizer and Reverb. While I did overall prefer the previous exercise more, alongside the tediousness of it, I found this exercise to be quite enjoyable and experimental. It was interesting to see how one audio clip can transform into various voices in various scenarios.
