Habe mir gerade mal auf Waves das manula zum Q10 angesehen, da ich das bundle morgen bekomme und ja eben auch einen Notch Filter möchte.
Also der Q10 hat eine Güte bis zu 100!! Diese Werte, so das manual, sind nicht gemäß der sonst üblichen engineering skala für den Q-Factor. Irgendwie ist der Algorithmus des Q10 anders aufgebaut....also er kann definitiv Notch und Spezialanwendungen.
Hier die Details:
About Q
Q is a way of expressing the frequency width of a filter in relation to the center frequency of the filter band and may be represented by the mathematical relationship: Fc/Fw (center frequency divided by frequency width at the traditional ‘-3dB point’, both in Hertz). For example, a Q of 2.0 at 1,000Hz gives a bandwidth of 500Hz (1000Hz divided by 2).
In the Q10, the filter design adopts a constant bandwidth rather than constant Q approach which means that the literal interpretation of Q is only strictly applicable at maximum boost setting. At other gain settings, the 6 Q10 Plug-in Manual width of the ‘bell’ is kept nominally the same as at maximum boost, not because we want to be awkward, but
because we feel that this approach makes the control of the equalizer more intuitive and more musical. In the Q10, when using small boosts and cuts, the Q value shown is approximately 5.5 times greater than the traditional engineering definition of Q. However, the basic principle of Q still applies; the higher the value of Q,
the sharper the filter and the narrower the range of frequencies that is affected.
For typical EQ applications, Q values of between 0.5 and 6 are typical, but for specialist applications, for example, notching out specific frequencies (such as hum), much higher values of Q (up to 100) may be used.
Figure 2 shows examples of both high and low Q settings. Note that because Q10 uses a variable Q filter topography, for most small boost/cut uses, these typical ‘engineering’ Q values of 0.5 to 6 would be shown as approximately 2.7 to 33 Q in the Q10.
