Podcast Recording Equipment 5 — Questions and Answers
Question 1: What does 'SPL' stand for, and why is it an important microphone specification?
- Signal Processing Level — how much EQ the mic applies
- Sound Pressure Level — the maximum loudness a mic can handle before distorting (Correct answer)
- Stereo Pan Level — how wide the stereo image is
- Sample Per Loop — how many samples are in a buffer
Correct answer: Sound Pressure Level — the maximum loudness a mic can handle before distorting
Sound Pressure Level (SPL) measures acoustic pressure; a microphone's maximum SPL rating indicates how loud a source it can record before the capsule or electronics clip and distort.
Question 2: A podcaster wants to record a co-host across the table without the microphones picking up each other. What microphone placement technique helps most?
- Point both microphones toward the ceiling
- Use cardioid mics aimed at each host with the null (rear) of each mic facing away from the other host (Correct answer)
- Use omnidirectional mics pointing at each other
- Wrap microphone cables around the stands
Correct answer: Use cardioid mics aimed at each host with the null (rear) of each mic facing away from the other host
Cardioid microphones reject audio from the rear (null point), so positioning each mic with its back facing the other host minimizes bleed between channels.
Question 3: What is 'clipping' in a podcast recording, and how can it be prevented?
- Clipping is when audio is cut too short; prevented by recording longer
- Clipping is when audio exceeds the maximum recordable level, creating distortion; prevented by reducing gain (Correct answer)
- Clipping is interference from radio signals; prevented by shielding cables
- Clipping is headphone bleed; prevented by using closed-back headphones
Correct answer: Clipping is when audio exceeds the maximum recordable level, creating distortion; prevented by reducing gain
Clipping occurs when an audio signal exceeds 0 dBFS (the maximum digital level), producing harsh distortion; it is prevented by setting gain so peaks stay below –6 dBFS.
Question 4: What type of microphone uses a thin metallic ribbon suspended in a magnetic field to generate an audio signal?
- Condenser microphone
- Dynamic microphone
- Ribbon microphone (Correct answer)
- Carbon microphone
Correct answer: Ribbon microphone
Ribbon microphones use a thin corrugated metal ribbon as both the diaphragm and the element that generates an electrical signal when it moves within a magnetic field.
Question 5: What is 'latency' in the context of podcast recording with an audio interface?
- The time it takes to export the final audio file
- The delay between a sound being made and when it is heard through monitoring headphones (Correct answer)
- The sensitivity range of the microphone capsule
- The amount of compression applied to the signal
Correct answer: The delay between a sound being made and when it is heard through monitoring headphones
Latency is the processing delay between the audio input and output; low latency is critical for real-time headphone monitoring so hosts don't hear a distracting echo of themselves.
Question 6: Which of the following best describes the difference between a 'large-diaphragm' and 'small-diaphragm' condenser microphone?
- Large-diaphragm mics are always omnidirectional; small-diaphragm mics are always cardioid
- Large-diaphragm mics have a warmer, more colored sound often preferred for vocals; small-diaphragm mics are more accurate and consistent off-axis (Correct answer)
- Large-diaphragm mics use XLR; small-diaphragm mics use USB
- Large-diaphragm mics do not require phantom power; small-diaphragm mics do
Correct answer: Large-diaphragm mics have a warmer, more colored sound often preferred for vocals; small-diaphragm mics are more accurate and consistent off-axis
Large-diaphragm condensers tend to add warmth and character, making them popular for podcast vocals, while small-diaphragm condensers offer a flatter, more accurate response suited to instruments and room recording.
Question 7: A podcaster records outdoors and hears heavy wind noise. Which accessory is specifically designed to reduce wind noise on a microphone?
- A reflection filter
- A windscreen or dead cat (furry wind muff) (Correct answer)
- A shock mount
- A DI box
Correct answer: A windscreen or dead cat (furry wind muff)
A windscreen (foam) or 'dead cat' (furry windshield) wraps around the microphone to break up airflow before it hits the capsule, drastically reducing wind noise in outdoor recordings.
