4.2 Microphone Techniques and Studio Etiquette

Microphone techniques are crucial for capturing high-quality audio. From choosing the right mic type to proper placement and handling, these skills can make or break a recording. Voice actors must also master techniques like breath control and articulation to deliver clear, emotive performances.

Troubleshooting common voice recording issues is essential. Addressing problems like plosives, sibilance, and background noise ensures clean audio. Proper studio etiquette and collaboration skills are equally important, fostering a professional environment where creativity can thrive and projects run smoothly.

1 of 3

• Microphone types
  • Dynamic microphones withstand high sound pressure levels making them suitable for live performances and broadcasts (Shure SM7B)
  • Condenser microphones capture detailed sound but require phantom power, ideal for studio recordings (Neumann U87)
• Microphone polar patterns determine sensitivity to sound from different directions
  • Cardioid picks up sound primarily from the front, reducing side and rear noise (Rode NT1-A)
  • Omnidirectional captures sound equally from all directions, useful for ambient recording (Earthworks TC30)
  • Figure-8 sensitive to front and rear, less to sides, suitable for interviews (AKG C414)
• Microphone placement affects sound quality and minimizes unwanted noise
  • Distance of 6-12 inches from mouth balances proximity effect and room noise
  • Slightly off-axis angle reduces plosives and sibilance
  • Pop filter minimizes plosives from hard consonants (P, B)
• Voice acting techniques enhance performance and clarity
  • Proper posture with straight back, relaxed shoulders, and grounded feet improves breath support
  • Deep diaphragmatic breathing supports voice and controls pacing
  • Clear articulation and enunciation increase intelligibility
  • Emotional delivery using tone, inflection, and pacing conveys intended mood (excited, somber)

Voice recording troubleshooting

• Plosives create popping sounds from hard consonants
  1. Adjust microphone angle
  2. Use pop filter
  3. Modify pronunciation
• Sibilance produces harsh, hissing sounds from "S" and "SH"
  1. Adjust microphone angle
  2. Use de-esser
  3. Modify pronunciation
• Background noise from environment degrades recording quality
  • Use acoustic treatment (foam panels, diffusers)
  • Choose noise-canceling microphones (Sennheiser MKH 416)
  • Remove noise sources (fans, air conditioners)
• Clipping distortion occurs when input signal exceeds maximum level
  • Adjust input gain
  • Use limiter to prevent peaks
  • Increase distance from microphone
• Proximity effect boosts bass when microphone is close to sound source
  • Maintain consistent distance of 6-12 inches
  • Use high-pass filter to reduce low frequencies

Studio Etiquette and Collaboration

Studio etiquette essentials

• Arrive punctually for sessions to respect schedules and studio time
• Prepare by familiarizing yourself with the script and project requirements
• Silence cell phones and devices to prevent disruptive sounds during recording
• Avoid food and drinks near equipment to protect from damage (coffee spills, crumbs)
• Handle studio equipment with care and follow instructions from engineers
• Communicate clearly and respectfully with all studio personnel

Collaboration in studio environments

• Understand roles and responsibilities for effective teamwork
  • Voice actor delivers performance per direction
  • Sound engineer manages technical aspects and ensures audio quality
  • Director provides guidance and feedback to shape performance
• Maintain open communication for a smooth recording process
  • Listen attentively to instructions and feedback
  • Ask clarifying questions when needed
  • Offer constructive feedback and suggestions respectfully
• Demonstrate professionalism to foster positive collaboration
  • Maintain respectful attitude towards all team members
  • Be receptive to constructive criticism and willing to adapt
  • Respect expertise and decisions of sound engineer and director
