sound 

human 20hz-20000hz is what we can hear and it gets less as you get older
(elephants have herds and super herds because they use lower frequencies)

wavelengths / waveform= sign wave

there are two channels l and r (left and right)

we record l and r and voice

always use two microphones the on board microphone and the external microphone (shotgun mic)(416) directional mic all of this goes of the boom

you record with two microphones because you get sound from different areas

the on board mic will record ambient sound and voice and thee mic is only the voice an Don background ambient sound
and you use two incase one gets broken or corrupted but mic os also a lot better quallity
so then you have close up voice and ambient so that you could create and mix to give a good effect so that when you coming then you give a story and understand whats going on with out having to watch visuals as well as the audio person will record wild track and ambient sound only so then you have everything you have to build
a soundscape

vu meter (virtually useless)
Image result for vu meter

ppm meters

Image result for ppm meter

voice should peak at 5.5pm
sound effects are at 3ppm               - audio level
music are at 4ppm / programs

but for adds they are at 6ppm          - peak


on timeline in the top left there is 00:00:00:00 is called time code
                                                        h  m   s    f
time code counts to 0 to 24
and then we learnt how to start a time code which all you do is you go file black video and then you go and go to the menu next to time and then go to start time and set that time to what you want
