This is a presentation I created for my The Technology of Music Production class by Berklee Online on Coursera. I didn't know anything about musicology, sound-making devices or instruments but just started from "0" and I'm enjoying it! (presentation created using Canva, pictures are the free ones from there).

3. WHAT IS A
MICROPHONE?
Microphone is a transducer device that
converts one form of energy (sound, air
pressure) to another (digital form,
voltage variation - binary information).
There are two types of microphones;
DynamicMicrophone
CondenserMicrophone

4. DYNAMIC
MICROPHONE
Typically used on live stage
Less sensitive, rugged, less prone
to feedback (less frequency
response)
Shure SM58

5. DYNAMIC
MICROPHONE
Shure SM58
Frequency response of a
microphone is how sensitive the
microphone is across the human
hearing range.

6. CONDENSER
MICROPHONE
For studio use
More sensitive, accurate
Typically have a better high end
frequency response

7. CONDENSER
MICROPHONE
AKG C414 XLII
Useful in a wide range of
situations and it picks things up
very accurately.

8. POLAR
PATTERNS
The polar pattern of a microphone
is a diagram that shows from what
directions the microphone is
sensitive

9. POLAR
PATTERNS
Useful for isolating a sound source
from its environment
DIRECTIONAL
MICROPHONE

10. POLAR
PATTERNS
Good for capturing the sound of
an environment
OMNIDIRECTIONAL
MICROPHONE

11. POLAR
PATTERNS
Have a focus sound in
a focused recording
that doesn't include
much of the room.
CARDIOID
DIRECTIONAL
MICROPHONE
Cardioid microphone also has supercardioid and
hypercardiod, and there just kind of flavors of
directional, and maybe bring in a little bit outside
of that directional space.

12. MICROPHONE
PLACEMENT
How the sound changes is going to
really tell you where you should place
the microphone.

In a recording studio setting, these voltage variations travel
through a wire to be processed in the Analog to Digital
Converter, then the computer, and then through a
speaker.
