This example shows a series of filters centred at 500Hz with Q of 1, 2 and 5 and a +6dB gainįilters can be stacked to produce complex shapes

Therefore Q = 500/100 = 5Īnother example, if the centre frequency is 100Hz but we maintain the same 100Hz bandwidth then Q = 100 / 100 = 1 Q is defined relative to the centre frequency of the filter, it is the centre frequency divided by the bandwidth of the filter where the bandwidth is defined by the +/- 'half boost/cut' dB points.įor example, if the centre frequency is 500Hz, the filter cuts 6dB and the -3dB points are at 450 and 550Hz then we have a bandwidth of 100Hz. This type of filter is also known as a proportional Q filter in rePhase Understanding Q MC implements a type of filter known as an RBJ filter after the author Robert Bristow-Johnson who published the EQ Cookbook. There is no practical limit to the maximum Q allowed. Channels: the channels to apply the filter to.the boost or cut applied at the centre frequency Gain: the maximum boost or cut applied by the filter, i.e.Bandwidth (Q): specifies the frequency range over which the filter will boost or cut, the higher the Q, the narrower the range over which the filter operates.Frequency: the centre frequency of the filter.Such a filter provides a cut or boost which is centred on the specified centre frequency This option creates a 'Peaking EQ' filter, such a filter may also be known as: See Verifying DSP Studio for details of how to measure your configuration.Īll graphs in this section were created using the method described in that page.Īllows the user to perform their own custom mixing, e.g. This page provides an explanation of how each option works as well as some guidance on typical uses. PEQ can be used for simple tasks like equalization and channel routing as well as advanced tasks such as creating a crossover for active speakers, performing bass management and applying a compressor. Media Center's DSP Studio includes a powerful and flexible parametric equalizer (PEQ) that can be configured with any number of filters. 17 Remove Low Frequencies (high pass filter).16 Remove High Frequencies (low pass filter).13.1 Managing Digital Headroom when Mixing.3.1 What type of peaking filter is used?.
