What do many audio interfaces have built-in to allow direct connection of guitars or basses without additional hardware?
Instrument Inputs
Apart from analog connections, what other type of outputs do many audio interfaces have for connecting to corresponding digital inputs?
Digital Outputs
What is the purpose of using closed-back headphones by performers in recording situations?
To minimize sound reflections in the recording space
What is the role of sound absorption panels in a recording space?
To minimize sound reflections bouncing off walls
How can the proximity effect affect a recording?
By disproportionately increasing low frequencies as the source gets closer to the microphone
What is one reason why it might not be practical to install sound-absorbing foam on the walls of a home studio?
It may not be logistically feasible
Why are pop filters recommended when recording vocals?
To reduce reflected sound from nearby walls
Which type of microphones are not affected by the proximity effect?
Omnidirectional microphones
What is the purpose of preamplification in the context of recording audio?
To boost the low voltage signal from microphones to a usable level
What is a common solution to the low voltage issue when using dynamic microphones?
Connecting to an audio interface with built-in microphone preamps
Which type of microphone works by moving a coil of wire around a magnet or vice versa?
Dynamic microphone
What is a disadvantage of dynamic microphones compared to other types?
Capturing nuances in performance poorly
Which microphone type is known for being affordable, sturdy, and suitable for recording louder sounds like guitars and drums?
Dynamic microphone
What feature distinguishes condenser microphones from dynamic microphones?
They need power to operate
Neumann U87 is mentioned in the text as an example of which type of microphone?
Condenser microphone
