Flanger 7 of 27 subtle 'simmering' effect? Phaser 8 of 27 what is cut-off freq? frequencies that will pass unaffected and which freq. will be cut 9 of 27 what is centre freq? the point at which a band-pass or notch filter will have most effect. 10 of 27 what is gain? how much cut or boost is applied to the effected freq. 11 of 27 what is resonance or Q control? determines bandwidth of frequencies that are affected- a high value will affect 12 of 27 what is slope? determines how quickly the filter will act at its cut-off point. 13 of 27 what is an LPF? Reduce the level of freq. above cut off freq. Let the freq. below this value pass through. 14 of 27 what is an HPF? Reduce level of freq. below cut of, allows high freq. un-affected. 15 of 27 What are band-pass filter? frequencies outside the scope of lpf/hpf pass unaffected. Graph- resembles bell curve. 16 of 27 what is a notch filter? band-pass with a very high Q value- used to cut particular frequency 17 of 27 what is a shelving filter? work at either end of the freq. spectrum. Cut/Boost freq. beyond a specfic frequency 18 of 27 what is equalisation? combination of various filters used in conjunction with eachother. 19 of 27 what is parametric EQ? EQ circuit based on band-pass filters with access to the parameters of the filters. 20 of 27 graphic EQ? seires of band-pass filters, sections with equally spaced center freq's organised according to musical intervals (8ve) 21 of 27 what is compression? reduces the dynamic range, making it more suitable for recorded media and broadcasting 22 of 27 explain limiting compressors with extreme settings, used to prevent signals increasing beyond a certain level 23 of 27 what is multi-band compression? allows the user to compress specific parts of the freq. range e.g. bass drum 24 of 27 what is de-essing? multi band compression for 's' 'sshh' 't' and 'ch' sounds 25 of 27 explain expansion? reduce the level of signals that fall belowe a set threshold, thus expanding drynamic range not reducing 26 of 27 and gating? noise gates = extreme expanders. reduces any signal below threshold to silence 27 of 27
