|
|
| a negative side of compression is that it… because the signal-to-noise or signal-to-quantization error ratio is lower at smaller amplitudes and the compressor raises those levels of ampltude |

|
|
| this control of a dynamics compressor determines how quickly the companding ratio is applied or released once the input signal passes the threshold |
|
| attack/release (setting these numbers too low can make a compander sound artificial) |

|
|
| two reasons tonal balance by subtracting frequencies rather than boosting them is good are… |
|

|
|
| the four types of EQs are… |
|
1. Low-pass (High-cut)
2. Band-pass
3. Band-reject (notch)
4. High-pass(Low-cut) |
|
| this type of EQ filter attempts to let low frequencies through while attenuating high frequencies. |
|
|
| these types of EQ filters selectively cut or pass only a specified frequency band |
|
| band-reject (notch) and band-pass |
|
| this type of EQ filter allows high frequencies to pass while attenuating low frequencies |
|
|
| what are the type types of EQ configurations? |
|
|
| this type of EQ configuration allows control over the precise frequency you wish to change (the center frequency) and the selectivity of the filter to the surrounding frequencies on either side of the center |
|
|
| the frequency range where the response is of the filter within 3dB or 50 percent of the peak level, this also determines how broad or wide a parametric filter shape will be |
|
|
| the amount of frequency selectivity or resonance is also called… |
|
|
| larger values of Q indicates a ________ filter shape while a smaller value of Q indicates a _____________ filter shape |
|
|
| this type of EQ configuration provides a single attenuation or gain slider or know for a fixed set of frequencies |
|
|
| this parameter of EQ is the amount of boost or cut in amplitude applied to the original sound expressed in dBs |

|
| for a parametric EQ frequency is… |
|
| the point of maximum amplitude change |
|
| the range of frequencies effected by the EQ are |
|
|
these EQ parameters are the inverse of one another
Ex. is one is 2 the other is 1/2 and is expressed in octaves |
|
|
| the EQ parameter that determines the rate that the sound goes from the effected portion to the non-effected portion and is expressed in dB/octave |
|
|
| this type of EQ control effects a broad range of frequencies evenly and the only controls are gain and frequency |
