Question 2

When recording an audiobook with a condenser microphone, what phantom power voltage is typically required?

Accepted Answer

48V

Most large-diaphragm condenser microphones require +48V phantom power supplied by the audio interface or mixer.

Question 3

What is a 'breath edit' in audiobook post-production?

Accepted Answer

Removing or reducing loud, distracting inhale sounds between sentences

Answer

Breath editing involves attenuating or deleting audible inhales that would distract the listener, while preserving natural-sounding pacing.

Question 4

In audiobook production, what does 'stereo vs. mono' refer to when choosing a delivery format?

Accepted Answer

Whether the final audio file has one channel or two channels of identical content

Answer

Most audiobook distributors require mono files because spoken word narration offers no benefit from stereo imaging and mono halves file size.

Question 5

What is the role of a 'high-pass filter' (HPF) in audiobook recording?

Accepted Answer

It cuts low-frequency rumble and handling noise below a set frequency

Answer

A high-pass filter removes low-frequency content such as AC hum, floor vibration, and mic handling noise that muddies the vocal track.
