What are the different types of sound capturing devices and how do they work? (Must discuss Dynamic and comdensor microphones, Direct Input devices as well as one other form of sound capturing)
Condenser Microphone
Dynamic Microphone
Direct Input (DI)
Sound Waves: "a longitudinal wave in an elastic medium, especially a wave producingan audible sensation." -Dictionary.com, it can also be described as a compression and rareification of air particles that creates a wave of pressure and displacement through the air.
​
Front Plate: The front plate acts as a diaphragm, it moves when struck by moving air particles recreating the compression and rareification of air particles by changing the distance between the front and back plate in a similar way to the air particles which in turn changes the capacitance.
Back Plate: The back plate is a fixed plate that will change the capacitance as the front plate moves closer and further away from it. This plate is charged by the battery or phantom power.
Battery: The battery provides the voltage that the plates need to pick up sound. This power can alternativley be provided by phantom power

Diaphram: The diaphram moves when hit my sound waves which in turn moves the wire coil
Coil: An electrical current is generated when ever a wire coil is moved close to a magnet, when the diaphram moves it pushed the coil closer and further away from the magnet.
Magnet: When the diaphram moves the wire coil interacts with the magnet generating an electric current.
Wire Carrying audio signal: The wires take the signal generated by the wire coil and takes it to a jack.
-15dB Pad: This switch will reduce the input level coming from the instrument to prevent the sound from distorting
"Thru": This allows the signal to pass straight through the DI to connect to an amp without its impedence being changed
1/4" Input: This is where the instrument is plugged in using a 1/4" unbalanced jack
XLR Out: Outputs a balanced 600 ohm output so that it can be connected to a PA system
Ground: This lifts the first pin to stop humming and buzzing caused by ground loops. Can also be used to provide a grounded connection to passive instruments.
I would chose the Beta 52a because of its frequency response designed more towards the rock and pop genres, it is also versatile in the way the frequency response changes based on the distance from the source. For example the further from the source the less low ends the mic picks up, this makes it useful for a wider range of genres during a recording or live performance.
​
I would choose the NT-55 because of its flat frequency response designed for use on snares. It's head plate can be changed allowing for a larger cardioid pattern, this means it picks up the snare better with limited bleed.
​
I would choose the NT-5 because of its flat frequency response making it suitable for a wide range of situations including overhead drum microphones. They are also suitable for stereo recording which makes them perfect for left and right overheads
​
I would choose a DI because you can plug the guitar directly into it which means you get no bleed from other instruments in your signal. It will also easily produce a clean signal which combined with no bleed makes post production very easy on that track
​
I would choose the Beta 58a for male vocals as their frequency response is suited towards deeper tones such as those from a male. Their super cardiod pattern allows for less bleed from other instruments
