Up the Audio
the production, questions are asked and answered in regards
to the audio equipment. What sound do we need - Interview,
background, ambiance? What mic do we need to bring?
are mics for each of these.
Lav is short for a lavalier microphone. This is a
tiny mic that hooks to the persons shirt or collar. The
mic is very directional and is used for interviews.
Handhelds are mostly used for news. They are held in the
hand and can be used during interviews or for stand up comments
by the newsperson.
Boom or shotgun mics
These are very directional microphones used to pick up voices
or noises. They sit on top of the camera or are held by
the audio person. Some people do not like the look of the
lav mic and so they will use a boom mic to record
interviews or sound bites.
Each of the mics above can be Wireless or Hardwired. The
wireless mics use a VH or UVH signal to transmit the audio
back to the camera. Hardwires use an audio cable to send
the signal back to the camera. Wireless allows for freedom
of movement but may have crackles and the batteries may
run down. The hardwire ties the subject to the camera but
is the safest and cleanest sound.
is a general list of items to consider for audio:
Mic - What microphone to use?
Mic placement - Where to put or hold the mic?
Cable or wireless - Does the person on camera need to be mobile?
If so, we use a wireless set up. if not, we use a cable
to go from camera to mic.
Lav or shotgun - Do we use a lav or a shotgun mic?
Purpose - What is the sound going to be used for? How is
it going to help tell the story?
