*Answers:

 

 

1. False

 

2. d

 

3.

1) Reduce (or eliminate) unwanted signals (or leakage of sounds) (such as unused Mics on stage or channels on a console)

2) Reduce Amp hiss after finish of guitar solo

 

4. De-esser

 

5. An EQ on a compressor of side chain will boost HF (5k ~ 20k); then compressor will only work with HF compressing sibilant sounds such as ’s’, ‘c’, ‘sh’, and ‘ch’. (reduce these (sibilant) sounds) The attack and release time are very short.

 

6. d

 

7. c

 

8. d
