- Pitch
- Loudness
- Timbre
(Obj.-Subj.)
Frequency{Hz}
Pitch
(Obj,-Subj.)
Amplitude
Loudness
(Obj.-Subj.)
Harmonic Content {Spectral Content}
Timbre
(Obj.-Subj.)
Dynamic Envelope {ASDR}
Timbre
Equalization/EQ
Enables the ability to adjust the volume level of a frequency(or range of frequencies) within a sound giving it the feel, tone, and character you want.
Sweepable EQ (Semi-parametric)
A convenient and flexible EQ that lets you sweep a certain range of frequencies w/a sweepable mid frequency
Parametric EQ
The most flexible type of EQ, gives you more control, bandwidth or Q
Where are Parametric EQ’s most commonly found?
in DAW’s
Graphic EQ
The most visually graphic and at a glance you can see what frequencies are boosted or cut
What are the shaped tools used to process the spectra content w/a Parametric EQ?
- Filters (High/Low pass)
- Shelves (High/Low shelves)
- Bell Curves
- Notch Filters
- Band-Pass Filters
What parameters are used to process spectral content w/a Parametric EQ?
- Frequency (sometimes referred to as Cut-Off Frequency)
- Gain (Amplitude)
- Quality Factor, or Q (width of the band)
- Slope: dB/Octave (for filters and shelves)
High Pass Filter/”HPF”
Allows high frequencies above the cutoff frequency to pass
Cutoff Frequency
The frequency at which the signal is attenuated 3dB
