Frequency relates to how often a sound wave repeats itself over a fixed period of time, with lower frequencies having slower vibrations and higher frequencies having faster vibrations. Frequency is measured in Hertz (Hz), with 1 Hz equaling one cycle per second. The human ear can detect frequencies between 20-20,000 Hz, with young children and women able to hear slightly higher frequencies. Timbre refers to the combination of frequencies that make up a sound. Equalizers, or EQs, are audio tools that can manipulate frequencies and timbres.

2. What is Frequency
 Frequency can be define as how often
wave repeats within a fixed amount of
time. It relates to how fast sound is
vibrating. Therefore low frequency will
have slow vibration while Higher
frequencies will vibrate faster.
 In music production Frequency is what a
computer can read while to human
hearing it is perceived as pitch.

3. How is Frequency Measured
 Frequency is measured in Hertz/ Hz.
With 1 Hz = Once per Second
 2hz = Twice per second
 10hz = 10times per second

4. Human Hearing + Frequency
 The human ears are able to hear things
ranging from
 20Hz – 20Khz/ 20,000hz
 Young children and Women tend to able
hear higher frequency up to 20,000hz

5. What is Timbre?
 Timbre can be define as a collection of
sounds at multiple frequencies.
 This then brings us to music production
tool which manipulates or edit
frequencies & Timbre.
 This Tool is called an Equalizer or EQ (A
filter effect tool

6. EQ / Filter Effect
Logic Pro X : Channel EQ
Comes equip with a Spectrum analyzer giving users eyes for
frequencies. Showing the amplitude and how the sound is
propagating .
