Reading and Writing

Chapter 8

Vibrating bodies create spherical sound waves

  • “Every sound, whether it be a human voice or a tree falling in the forest, is caused by something vibrating” (91, Schroeppel).
  • Every microphone has a diaphragm which vibrates whenever it is hit by sound waves.
  • Frequency: the closeness of the waves
    • The higher the frequency the number of waves (cycles per sound) or shriller the sound
    • The lower the frequency has a lower or deeper sound.
  • Amplitude: the size of the waves (what we think is loudness)

Microphones

  • Two types of microphones: dynamic and electret condenser
  • Dynamic Microphone
    • “The vibrating diaphragm moves a coil of wire inside a permanent magnet, creating an electric current” (95, Schroeppel).
  • Electret Condenser
    • “The diaphragm of an electret condenser microphone is actually one plate of a condenser, or capacitor” (95, Schroeppel).

Microphone Pickup Patterns

  • This is the area where the mic is most sensitive to incoming sound waves
  • Omnidirectional pickup pattern
    • Picks up sound equally well from every direction
  • Cardioid pickup pattern
    • Looks like a heart and picks up the greatest sensitivity from the front of the microphone

Types of Microphones

  • Lavalier: small, electret condenser mike, normally designed with an omnidirectional pickup patter. They’re designed to be worn on the chest of the speaker, either by a cord or attached by a clip.
  • Hand Mike: the most versatile and widely used mike in the industry. It can be either a dynamic or condenser with either an omnidirectional or a cardioid pickup pattern.
  • Super cardioid or shotgun mike: great mike to use for distant sounds or in uncontrolled situations, like television news coverage.

Sound Waves Bounce

  • Reverberation: the total effect of the reflected sound waves

Wild Effects

  • Sync effects: recorded at the same time as the picture
  • Wild effects: any noticeable sound effect from a scene (car door slamming, car starting), should be recorded up close without picture.

Recording Voices and Presence

  • Sync sound: sound recorded in synchronization with the camera (person talking on camera)
  • Voice-over: a narrative voice heard over the picture but not seen
  • Presence (ambience): the sound of a location without any single sound predominating. For example, if you’re in a lab, have the beeps of lab equipment.

Voice-slate and keep a sound log

  • A voice-slate is a recorded description of everything you record. It’s like a normal slate used in video, but there’s no physical video of it.

“Record your voices, sound effects, and presence separately and cleanly. This will give you maximum flexibility in your mix” (110, Schroeppel).

Research to Inform

I really like this Podcast as I am a Packers fan and I try to find every possible Packers related article or video. This one definitely stood out to me, because in most of the podcasts I’ve seen you never actually see the person talking. You do with this one and it gives it a more personal feeling. A lot of emotion and feelings are conveyed through facial expressions and hand movements, and those can’t be seen if it’s just audio. You can really tell how passionate Pour Another is about the Packers.

I really like H3H3’s regular YouTube channel, so it only makes sense that I also enjoy his podcasts as well. Like Pour Another, you see everyone on this podcast. What’s different however, is that Ethan Klein brings on guests to interview. In this specific episode, he brought on my favorite YouTuber Videogamedunkey. Ethan Klein also uses images in the podcast to not only explain what he’s talking about but show it as well. I do think that the audio could be a little louder.

This is the first podcast of the three that I’ve chosen that doesn’t include any video of the people talking. I don’t think that takes away anything from it though. Even though there’s no video, there is a visual aspect to the podcast. This podcast seems to just be two friends talking about the NBA, and I really enjoy that. Last semester I did a Packers podcast with one of my good friends and I had so much fun doing it.

Create

I chose this topic, because I found it incredibly interesting and an amazing feat in the scientific world. I had originally thought about doing a sports podcast as I had done one in the past, but I decided to do one that more people would be interested in. This is definitely a difficult topic to talk about on a podcast, as I don’t really know much about it. It required a lot of research on my part to find out everything I could. I do think it will be difficult to find sound effects for this type of podcast, as it’s more of a narrative and informative podcast. It also seems a little inappropriate to add sound effects to a podcast talking about HIV/AIDs.
