It is useful when the sound source is close and not too loud.

It is suitable for recording sound which pitch is

predominantly bass or mid-range, for example, the Pop

concert or rock n roll. It can be used to record sound

produced by musical instrument such as the percussion,

guitar and used in video camera. The output volume is low,

it is robust (tough) and its price is relatively cheaper as

compared to the other types of microphones.

Condenser microphones This type of microphone is quite sensitive and more fragile.

It is able to pick up high frequency signals and distant

sound. It is able produces louder output.

It is suitable to be used for studio recording and for

orchestra performance.

Unidirectional microphones Able to pick up sound from one direction only. Normally it

receives sound signal from the front part of the microphone.

Its pickup pattern can either be cardioids and Hyper

cardioids. It is useful when we need to eliminate the noise

from the surrounding environment.

Bi-directional microphones It can pick up sound form the opposite direction, which is

ideal for dialogue or for meeting.

Omni directional microphones It picks up sound from all direction and is ideal when there

is only one microphone to be shared by many speakers. It

may also be hang from the ceiling to receive sound signals

PLANNING & PREPARATION

1. Identify the objectives and learning outcomes By referring to syllabus and standards, we can identify the objectives and standards, scopes of

the contents, the types of learning activities, and values which should be included in theaudio presentation.

and elaboration which may effectively capture the students attention, arousetheir interest and convey the essential massage successfully.

3. Obtain the information (The topic, skills, content)and the relevantresources (sound effects, background music, CDs, etc.)

4. Preparing the script

Clearly define the sequencing of the content, the relevant sound effects for aparticular scenario, when and how the background music should come in,when to pause, phrases which needed emphasis and alike.

The script is a guide for the producer, the talents as well as the productioncrews. It helps the team to visualize how to act out a scene, to pin point theappropriate time to dub in the background music and/ or the sound effectsand so on and so forth.
