E N D
HEADPHONES • Remember Various Types • How does noise-cancelling work
Types of EQ • Know the differences between Graphic and Parametric • Understand Fixed vs. Variable
Types of Compression • Know what a Limiter and Brick-wall limiter is • Understand Attack and Release • What is a noise gate?
Reverb Parameters • Direct vs. Reflected Sound • Reverb Time • Reverb Types (analog & digital)
Dynamic Range • 16-bit CD: 96dB • 24-bit: 144dB • Know HEADROOM
S/N RATIO • Signal to Noise Ratio • Same concept as Dynamic Range
Pink & White Noise • WHITE is ‘Flat’ or ‘Linear’ across the spectrum • PINK has a 3dB drop per octave
DITHER • Intentionally adds NOISE • Increases perceived dynamic range • Deals with the LSB (least significant bit)
DISTORTION • CLIPPING: Digital Distortion (hard clipping) • Analog Distortion: Warmth or overdrive
NOISE • Low-Level hiss and hum • Generated by equipment or interference • Different from Distortion
NORMALISING • Increasing the sound to the maximum level • All sound levels stay the same in relation to one another
PSYCHOACOSTICS • SUBJECTIVE HUMAN HEARING • Beat Frequencies: Two very close pitches • MASKING: sounds hiding one another
LAST WEEK’S PROJECT • Types of Microphones • Polar Patterns and stereo setup • Any issues encountered
LISTENING SECTION • Pinpointing Frequencies • Frequency Cutoff • Reverb Types • Gain Levels • MP3 Compression • Song Analysis
