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.

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
Adjust microphone angle
Use pop filter
Modify pronunciation
Sibilance produces harsh, hissing sounds from "S" and "SH"
Adjust microphone angle
Use de-esser
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
