Podcast Production Audio Engineering & Mixing 2 — Questions and Answers
Question 1: What does bit depth determine in digital audio recording?
- The dynamic range and resolution of the audio (Correct answer)
- The sample rate of the recording
- The file format used for export
- The number of audio channels
Correct answer: The dynamic range and resolution of the audio
Bit depth determines the dynamic range of digital audio; 16-bit provides 96 dB of dynamic range while 24-bit provides 144 dB.
Question 2: What is the ideal gain staging practice when recording podcast vocals?
- Set input levels to peak around -12 to -6 dBFS (Correct answer)
- Set input levels to hit 0 dBFS consistently
- Record as quietly as possible and boost in post
- Use automatic gain control (AGC) for all recordings
Correct answer: Set input levels to peak around -12 to -6 dBFS
Recording with peaks around -12 to -6 dBFS provides sufficient headroom to prevent clipping while maintaining a strong signal-to-noise ratio.
Question 3: What is 'de-essing' in podcast audio production?
- Reducing harsh sibilant 's' and 'sh' sounds in a vocal track (Correct answer)
- Removing echo from a recording
- Lowering the bass frequencies in a mix
- Cutting the high frequencies above 8 kHz
Correct answer: Reducing harsh sibilant 's' and 'sh' sounds in a vocal track
A de-esser is a frequency-specific compressor that targets and attenuates harsh sibilant sounds like 's' and 'sh' that can be painful on headphones.
Question 4: Which stereo field technique is most commonly used when mixing a multi-host podcast?
- Panning each host slightly left or right to separate voices (Correct answer)
- Using mono for all tracks to ensure compatibility
- Adding reverb to each track for spatial depth
- Applying heavy compression to collapse the stereo field
Correct answer: Panning each host slightly left or right to separate voices
Panning hosts to slightly different positions in the stereo field helps listeners distinguish between voices and creates a natural conversational feel.
Question 5: What is the purpose of multiband compression in podcast mastering?
- To compress different frequency ranges independently for a balanced final mix (Correct answer)
- To remove all frequencies below 100 Hz
- To increase the stereo width of the recording
- To synchronize multiple audio tracks
Correct answer: To compress different frequency ranges independently for a balanced final mix
Multiband compression allows control over each frequency range separately, preventing one part of the spectrum from dominating and creating a polished, broadcast-ready master.
Question 6: What does 'room tone' refer to in podcast production?
- The ambient background sound of a recording space recorded without speech (Correct answer)
- The acoustic reverb characteristics of a studio
- The tonal quality of a microphone's frequency response
- The hum from electrical interference in a recording space
Correct answer: The ambient background sound of a recording space recorded without speech
Room tone is a few seconds of ambient silence recorded in the recording space, used by editors to fill gaps and maintain consistent background noise throughout the episode.
