How to Conduct a Recording Studio Test This methodology shows you how to conduct a test on your recording studio to prepare an audio clip for analysis. 1. Set up your mic and recording system as normal with popshield in place. Record with your mouth directly aiming at the mic capsule and 6 inches away from the front of the mic itself. 2. Find some dialogue to read – just a small paragraph will do, and project it (volume) slightly above normal speech, as if you’re talking to someone about 10 feet away. 3. With this level of projection, set your recording input gain so that the highest peaks of your dialogue’s waveform are between 4 to 6db. 4. With this level set, start the recording (at 48kHz, 24 bit wav) and leave the booth or recording area so that there is no interference from yourself in the recording. Record the room silence for one minute. 5. Whilst still recording, reenter the booth and go back to the mic position as normal, then record the paragraph at the same projection level. 6. Clap your hands once near the mic. This will invariably clip the recording, so do it again quieter until the recording doesn’t clip. 7. Repeat step #6 at various points around the studio to capture the different reflections around the studio, especially near any reflective surfaces you may have, such as glass. Your clip is then ready for analysis. You will then be able to analyze the noise floor in the 1minute silence, hear the room when talking and measure the reverberancedecaytail of the claps at the end of the clip.

How  to  Conduct  a  Recording  Studio  Test    This  methodology  shows  you  how  to  conduct  a  test  on  your  recording  studio  to  prepare  an  audio  clip  for  analysis.      

1. Set  up  your  mic  and  recording  system  as  normal  with  pop-­‐shield  in  place.  Record  with  your  mouth  directly  aiming  at  the  mic  capsule  and  6  inches  away  from  the  front  of  the  mic  itself.  

2. Find  some  dialogue  to  read  –  just  a  small  paragraph  will  do,  and  project  it  (volume)  slightly  above  normal  speech,  as  if  you’re  talking  to  someone  about  10  feet  away.    

3. With  this  level  of  projection,  set  your  recording  input  gain  so  that  the  highest  peaks  of  your  dialogue’s  waveform  are  between  -­‐4  to  -­‐6db.    

4. With  this  level  set,  start  the  recording  (at  48kHz,  24  bit  wav)  and  leave  the  booth  or  recording  area  so  that  there  is  no  interference  from  yourself  in  the  recording.  Record  the  room  silence  for  one  minute.    

5. Whilst  still  recording,  re-­‐enter  the  booth  and  go  back  to  the  mic  position  as  normal,  then  record  the  paragraph  at  the  same  projection  level.    

6. Clap  your  hands  once  near  the  mic.  This  will  invariably  clip  the  recording,  so  do  it  again  quieter  until  the  recording  doesn’t  clip.    

7. Repeat  step  #6  at  various  points  around  the  studio  to  capture  the  different  reflections  around  the  studio,  especially  near  any  reflective  surfaces  you  may  have,  such  as  glass.    

 Your  clip  is  then  ready  for  analysis.  You  will  then  be  able  to  analyze  the  noise  floor  in  the  1-­‐minute  silence,  hear  the  room  when  talking  and  measure  the  reverberance-­‐decay-­‐tail  of  the  claps  at  the  end  of  the  clip.
