WEEK 5 : INTRODUCTION TO AUDIO : UNIT 1

In the Beginning of this lesson we learned how 60 per cent of film is by audio. We learnt how Microphones give all sorts of different qualities and sound effects.

We had certain kinds of tasks in which we grab sounds from the interior and the exterior. like grabbing the sound of rain or a spaceship or even footsteps.

We even saw a couple of intriguing and compelling clips of Documentaries of sophisticated sound composers providing the sound pieces for it’s film they are required to do.

We were also shown 3 different types of microphones.

Microphones are suited to handle high volumes levels such as from certain musical elements and instruments or amplifiers.

Condenser Microphone:

Condenser Microphone requires power from batteries or an external source. The audio signal from this microphone is stronger than that from a Dynamic microphone.

More Sensitive/responsive than Dynamic mics so well suited to capturing subtle nuances in sound. Not ideal for high volumes as sensitivity makes them prone to distort.

POLAR PATTERNS.

Picks up audio equally well in all directions.

USES : Recording ambient sound, recording more than one person talking or singing at once e.g. Choirs, orchestras,debates etc.

CARDIOID.

Heart shaped pattern, can also be considered unidirectional.

HYPER CARDIOID.

Slightly narrower pick up pattern than cardioid with slight rear pick up pattern.

hyper cardioid microphones are similar to cardioid but have a tighter 100 degree.

SUPERCARDIOID.

Supercardioid microphones give a much more narrower pickup than cardioid and a greater rejection of ambient sound. However they also pick up a small amount of ambient sound. For this reason it is important to place the speakers on the dead spots.
