Podcast Recording Project

Summary

In this project I researched my favorite song, Friction by Imagine Dragons. I learned about its composition, as well as the meanings behind it. I then made a podcast about it, playing clips of the song and talking about what I researched.

Terms

  • Volume Fader
    • A sliding mechanism on a mixer that adjusts volume
  • Pan (Stereo Image)
    • A knob that moves sound to he left or right on speakers or headphones
  • Clipping
    • When the amplitude is too high and causes distortion
  • Equalizer (EQ)
    • A device that controls frequencies to alter sound
  • Bus Track
    • A track that can send signals to other tracks
  • Automation
    • Setting up volume and pan to automatically change during playbak
  • Audio Compression
    • Louder parts made softer and soft parts made louder
  • Bass
    • Lower range of sounds
  • Treble
    • Higher range of sounds
  • Reverb
    • A device that can make a sound source sound as if it were in a room or hallway

Audio Mixed Podcast

What I Learned

Doing this project I learned a lot about my favorite song. I also learned how to make a podcast using a song and a voice over. A problem I had with this project was getting all of my talking to line up with the song at the right times and how to get the volume to stay consistent throughout the whole podcast. I solved this by going slowly through the whole podcast to make sure that everything lined up correctly.

Microphones and Recording Project

Summary

In this projects we learned how microphones work and got some experience using them. We tested out many popular microphones to see which ones made our voices sound best and what the qualities of those microphones are.

Microphone Audition Podcast

My Favorite Microphone Specifications (AKG C1000S)

  • Sensitivity – 6 mV/Pa
  • Impedance – 200 Ω
  • Voltage – 9 to 52 V
  • Pick up pattern – Cardioid
  • Self Noise level – 21 dB
  • Frequency response – 50 Hz
  • Transient response – fast

Terms and Concepts

  • Dynamic Mic.
    • Diaphragm connected to coils held by a magnet
    • When spoken into sound waves move coils
    • Good for loud noises, bad for quiet
  • Condenser Mic.
    • Fixed plate and diaphragm plate
    • Diaphragm plate moves creating electrical signals
    • Sensitive
  • Omnidirectional pattern
    • Can pickup sound from all directions
  • Cardioid pattern
    • Picks up what it in front of the mic
  • Bi-directional pattern
    • Picks up sound from 2 opposite directions
  • Transduction
    • The process of changing one form of energy to another
  • Voltage
    • Amount of electricity measured in volts
  • Phantom Power
    • Power from the mixer to the microphone
  • Sensitivity
    • Voltage output at a certain sound level
  • Frequency Response
    • Range of sound microphone can reproduce
    • How sensitive the mic is at a distance
  • Transient
    • An abrupt change in volume level
  • Placement
    • Where the microphone is so that it captures different sounds
  • Proximity Effect
    • When the microphone is close to the source and cuts out background noise
  • Output
    • Where the sound leaves the system
  • Characteristics
    • The Relative Response and Frequency in hertz graph that shows the quality of the microphone
  • Noise Rating
    • The signal to noise ratio
  • Mic. Clip
    • Holds microphone to the stand
  • Mic. Stand
    • Holds up the microphone so the speaker doesn’t have to
  • Windscreen/Pop Filter
    • Covers the microphone to reduce breathing noises
  • Direct Box
    • Connects amplified instruments to mixers

What I Learned

Doing this project I learned about the basics of recording with microphones. I learned that my voice sounds best with cardioid condenser microphones, especially the AKG C1000S. A problem I solved was when the microphones produced louder and quieter sounds, I changed the volume levels on GarageBand so the entire audition was at the same volume.
