How to Reduce Unwanted
Electrical and Acoustical
 Noise When Recording
       Assignment 4
       Mahta Moattari
Introduction
O Hi, my name is Mahta. I¡¯m from
 Fredericton, NB, Canada. In this
 assignment I like to talk about how to
 reduce unwanted electrical and acoustical
 noise when recording. I hope you find it
 useful.
Unwanted noises
O We have two type of noise when we
  record music:
  O Acoustic noise: noise of the space and
    everything that comes into it
  O electrical noise: noises that the gear itself
    creates
O There are different strategies to avoid
  these noises while recording
Recording and space
O Whenever you are recording you need to
  remember, you are recording instrument
  in the space.
O The more noise free space will result in a
  cleaner record.
O The cleaner the record the more option
  you have to work with
Find that noise
O Listen carefully to find the different noise
    resource and somehow isolate them, for
    example:
O    To avoid computer¡¯s fan noise, move
    farther away
O    Put a blanket or a pillow against the
    window
O   Heat, air conditioning and TV cause noise
    too
O   Before recording, listen and try to reduce
    all those different types of noise
Find that noise
O Every piece of gear makes some kind of
  electrical noise
O The self-noise specification can be found
  in manual
O To reduce that noise, use as few pieces
  of gear as possible
O Also use short cables and use balanced
  cables, like XLR cables or TRS cables as
  much as possible
Find that noise
O The power system of your studio can also
  cause electrical noise
O Turn off the dimmers and light dimmers
O Use high quality gear
O Reduce the amount of noise by mike
  placement, also by not turning the mike
  pre-up and instead get the mike closer to
  the source
Find that noise

O Mike polar pattern also can have an
  impact on noise
O A directional microphone will focus on the
  source and reject the sound of the room
Tools that can reduce noise
O In the post production process we have
  some tools that can reduce noise
O We should not try to fix the noise in the
  mix
O But these tools are important because
  noise can be useful musically
