TASK 1

2. Sound is vibration moving through the air. Acoustics are everywhere, they are surfaces that sound reflect off. When you
are recording in the studio the sound is nice because it is a small place where there is not a lot of time to reflect, this is
called a controlled environment. If the surface is hard it will reflect but if the surface is soft the sound will die quickly
and sound better, for example if you have sound absorption which is soft in a studio the sound will be clear.
Reverberation is the time the sound takes to die out. Reverb prolongs the sound, you can have a long reverb or short
reverb, the reverb would be longer if you are in a sound reflective place like a bathroom with titles everywhere. Its
shorter if you are in a smaller space with no reflective materials. It wouldn’t be good to record outside because there
will be too many sounds to block out recording inside the studio for the best audio. You can simulate acoustics on
different software's such as audacity and logic, it will be under tools and effects. If you were to record out side in a
urban atmosphere you would have to have a wind shield so the wind doesn’t pass through in the audio.
Studio walls have odd patterns to make it harder for the sound to travel through, its important, that sound cannot travel
through walls, as it cause sound leaking, disruption of recording etc. this can be tricky as sound waves travel frequently,
they eventually hit obstacles, the percentage of the sound is reflected and the rest is absorbed, and passed through
whatever the material is. An echo or reproduction of the sound can be heard if the sound reflects off a smooth flat
surface, this is why. It is designed for the sound to be captured and absorbed in.
Reverberation is the left over sound in a particular area or space a period after the original sound has been produced.
Reverberation is caused by sound being produced in a bounded space or area, resulting to a large number of echoes to
compile up and then slowly decease due to the walls or air absorbing the sound.
Task 1 Indoor and some outdoor

3. Outdoor
It is important you know exactly where you need to record depending on what you would like
to record. For example, if you want to record a scene within a food shop you cannot record in
the woods as the background atmosphere is different as there are different noises. Unwanted
noise is the noise in the background of a recording or audio track, that shouldn’t be there, for
example vocals recorded on the street may be occasionally be interrupted by noisy individuals
or moving transport, unwanted noise can be avoided by recording in a controlled and
extremely silent room like a studio.
When recording with a microphone (especially outdoors)using a wind shield is a key method to
avoiding wind interruptions, the microphones that are specially built for this are called boom
microphones.

TASK 2

5. Dynamic microphones are great when you want to capture sound which is loud and close, They also have the benefit of being
tough and inexpensive. They also don't require phantom power or batteries.
Capacitor microphones are great at responding to very high audio frequencies, and are a lot more sensitive than their dynamic
mics. they require less amplification than dynamic models to produce the same output level from the same signal source,
making them more suitable for quieter or distant sound sources.
background sounds will not be heard with the lavalier mic. It is designed best for lecturers, TV performers, interviewers or
interviewees. It has a integral 80 Hz high-pass filter that provides easy switching from a flat frequency response to a low-end
roll-off.
A ribbon microphone is a type of microphone that uses a thin aluminium, duralumin or Nano film ribbon placed between the
poles of a magnet to generate voltages by electromagnetic induction. Ribbon microphones are typically bidirectional, meaning
they pick up sounds equally well from either side of the microphone.
Electric condensers are a stable dielectric material with a permanently embedded static electric charge. it is a type of condenser
microphone, which eliminates the need for a polarizing power supply by using a permanently charged material.
radio microphones, have a small, battery-powered radio transmitter in the microphone body, which transmits the audio signal
from the microphone by radio waves to a nearby receiver unit, which recovers the audio
Cables: 3-pin XLR connectors are mainly used for balanced audio signals. Using a balanced signal reduces the risk of inference.
There are two types of 6.5mm Jacks: Mono and stereo. The mono jack has a tip and a sleeve, the stereo jack has ring, a tip and a
sleeve.

TASK 3

7. There are different editing software's for audio such as Audacity and logic. Mono indicates the
use of a single channel. Mono includes the use of a single microphone used to record a sound,
which is then played through a single channel through a speaker. Mono recording was used
before the development of stereo recording. The advantages of Mono recording are that file sizes
are around half the size of their stereo counterparts, High resolution files can be recorded with
relatively low file sizes, It is much easier to mix mono sounds than it is with stereo and mono
sounds are much easier to manipulate in editing programmes.
Mono recording has one independent audio channel, stereo has two channels. Signals that are
reproduced through stereo recording have an exact correlation with each other, so when the
sound is played back through either speakers or headphones, the sound is a mirrored
representation of the original recording. Stereo recording would be useful in situations that
require the use of sound perspective, for instance the clear location of instruments on a stage.
Editing is Using software to clean up unwanted background noise and add sound effects. You can
do this with different programmes such as logic or audacity. When recoding with a camera you
can use a fixed or detached mic for better sound. If you are away from the camera detached is
better but if your close you should fix it on the camera
