EQ

 

- Sound Design - "Equalization & Microphone Types"

What is the difference between dynamic and condenser microphones? In terms of sensitivity, condenser mics are more sensitive compared to dynamic mics. Dynamic mics also require no power, while condenser mics require a battery or phantom.

What is directionality? It is the "pickup pattern" of a microphone in which your microphone can pick up sound from a particular direction. There are three basic types such as omnidirectional, cardioid, and super-cardioid. Omnidirectional can pick up sounds equally from all directions, while cardioid is more sensitive to sounds from the front. 



Why would you use a lavalier? A shotgun? A dynamic? It all depends on the scene's situation. Lavaliers and shotguns are better used when the subject needs their hands free in the shot for things such as hand movements and presentations. Shotgun microphones are also ideal for scenes in which the subject is farther away from you due to its range. However, lavaliers and dynamic mics are also far more sensitive compared to dynamic mics, so dynamic mics may be ideal for situations in which there is a lot of background noise that the microphone can pick up.




What is EQ? It is the changing of balance between different frequency components in an audio signal.



How does an instrument or voice's timbre affect how we EQ? Different instruments and voices have the same fundamental frequency, but different timbre. This means that there is a possibility of overlapping between the two sounds, which can be nullified through the use of EQ.

How does masking affect recordings with multiple sounds? Masking makes it harder to identify individual sounds, creating an overlapping effect. 

How can you use filters to improve audio quality? Filters can be used to change the spectrum of the sound. including things such as low-pass, high-pass, and bell filters. These affect the shape of the bands, allowing you to manipulate sounds to achieve better quality.



Explain Additive and Subtractive EQ? Additive EQ boosts frequencies, whereas subtractive EQ cuts off offending frequencies.

On The Spot Post-Production

On The Spot - Post Production This was definitely the most time-consuming project out of all of them this year. Besides that, however, it was a lot of fun getting to film things outside of the classroom and put some own creative spin on my own work.  Choosing The Right Music I was inspired by a few things from the videos shown in class. For one thing, I learned just how important sound is as the actual video itself. The sound is able to captivate the audience by following a certain tone that is easy for the viewer to understand. This was the hardest thing for me to do as it required a lot of thinking on my part in order to captivate this same feeling- I couldn't just slap any random music and call it a day. The search for the right kind of music was the most annoying part of this project for me because of this. I would play some songs found on bensound over my project, but none of them worked out. A silly thing I found out was that Jazz songs actually fitted well in the background

The Camera - Aperture & Iris

Image
  - The Camera - "Aperture & Iris"                What is aperture?   It is essentially the "pupil" of a camera lens, in which the lens "open" and can be shrunk or enlarged in order to allow more or less light into the camera sensor.                  How does it affect exposure?   It changes the amount of light that is able to reach the camera sensor. Large, wide openings of the aperture will result in brighter photos because more light is passed. A smaller, tight opening of the aperture will result in darker photos because less light is passed. How does it affect depth of field?  A large aperture will yield greater background blur, whilst a small aperture will yield little background blur. How do you pick the right aperture for your scene?  When capturing photos in bright/dark environments, a smaller/larger aperture may want to be used since aperture affects exposure. This allows for less light on sunny photos, or more light on photos taken at night.
