1. PREP WORK - EQ What hardware FX units did you find?
What was the features of them?
Did anyone famous use them?

2. A2 - EQUALISATION
LEARNING OBJECTIVES: To RECOGNISE VARIOUS WAYS IN WHICH EQ CAN BE USED TO CREATIVELY EDIT AN AUDIO WAVEFORM

3. THE BIGGER PICTURE…

4. So… what is EQ used for? Bandwidth is…?
EQ is used to adjust the frequency of a sound through the use of various filters…
EQ gives us better analysis of frequency ranges and bandwidth’s of instruments.
Bandwidth is…?

5. WHAT TYPES OF FILTERS ARE THERE?
ONE AT A TIME, COME UP TO THE BOARD, LABEL THE AXIS’S AND DRAW A FILTER THAT YOU KNOW OF… There are 4 in total…

7. WHAT DO THEY SOUND LIKE? THIS FILTER IS CALLED A… HIGH PASS FILTER
LOW PASS FILTER
BAND-PASS FILTER
IF A BAND PASS FILTER _______________ THE FREQUENCIES, A BAND-STOP MUST _________ THE FREQUENCIES.

8. RECAP – EQ CAN BE USED TO…
MAKE RECORDINGS SOUND LESS MUDDY
MAKE RECORDINGS SOUND BRIGHTER
BOOST LOW FREQUENCIES TO MAKE INSTRUMENTS SOUND FATTER, SUCH AS BASS GUITAR
CUT LOW FREQUENCIES TO MAKE INSTRUMENTS SOUND THINNER

9. TASK – RECOGNISING FREQUENCIES WORKSHEET

10. So.. We’ve covered different types of filters… Now let’s cover different types of EQ

11. USING GOOGLE, RESEARCH ‘GRAPHIC EQ’… WHAT DO YOU NOTICE?
GRAPHIC EQ CONSISTS OF MULTIPLE SLIDERS FOR CONTROLLING THE BOOSTING AND CUTTING OF SPECIFIC BANDS OR FREQUENCIES…
A TYPICAL FIVE-BAND GRAPHIC EQ WILL HAVE SLIDERS OF FIVE FIXED FREQUENCIES:
30Hz (Low Bass)
100Hz (Mid-Bass)
1kHz (midrange)
10kHz (Upper midrange)
20kHz (Treble or high-frequency)
QUESTION: WHAT DO YOU THINK THIS ALLOWS FOR BETTER?
Answer: Tone Control

12. LET’S GET MORE COMPLEX… PARAMETRIC EQ
A MORE COMPLEX TYPE OF EQ IS PARAMETRIC EQ, WHICH CONTROLS MORE PARAMETERS OF THE SOUND THAN A GRAPHIC EQ.
A PARAMETRIC EQ CAN CONTROL THREE ASPECTS OF EACH FREQUENCY:
Level (Boost or Cut)
The centre of the primary frequency featured
Bandwidth range of each frequency
SO… What do we think the benefit of using a parametric EQ is?
Answer: Allows more detailed control of the sound and permits finer frequency adjustments

14. TASK – COMPLETE THE A2 Topic Sheet on EQ
The bottom right section (SOS 2008) requires you to type in ‘What’s the frequency sound on sound 2008’ into google to load up the article.
On this section you are listing specific frequencies for each instrument
