Audio for eLearning Simplified:
Noise, Distortion, & Gain


   presented by Robert Hershenow
    Monday May 21, 8:30-9:30 AM
ISE      NOISE
        is any sound
         other than
NO

         what you’re
          trying to
            record
NOISE is
like a weed...
it might be
    pretty!
      —
but not if it’s
in the wrong
     place
N   O    DISTORTION
       RTI
                      is a
               misrepresentation
    TO


                 of the sound
DIS
DISTORTION
   can be friendly


(technically speaking,
tone controls distort
  the audio signal)
DISTORTION
 can be unfriendly


  (like when you
   overload the
       input)
IN        GAIN
       is a measure of
         amplification
GA
too little

GAIN
  invites

NOISE
too much

  GAIN
   invites
DISTORTION
how do you get it
JUST RIGHT?
Come to the
Education Progression
 Monday May 21, 8:30 AM
   Find out about noise, distortion, and gain, why
    they’re so important in recording, and how to
        deal with them - all in simple terms.
