General recording instructions

Hardware:

Ideal recording setting:

• The ideal recording setting is a quiet and private space with minimal or no ambient noise. Some additional considerations for ensuring an ideal recording environment:
  • Switching off electronics that might emit low frequency sounds (lamps that buzz, thermostats, Desktop Computers, monitors, fans etc)
  • Carpeted place (if possible)
  • no vaulted ceilings and as deep into the house or building as possible (have less reverberation).
  • No windows
• If recording at home, we ask participants to identify a place that might meet these requirements.
