Stereo Equaliser based on approximate brick-wall filtering
Illustrates the use of the Brick-wall 8-band Equaliser block for performing stereo equalisation over 8 octave frequency
bands. The block is implemented by approximate brick-wall filtering in the frequency domain (i.e. by directly weighting the
FFT data by the chosen gain values across the frequency range). This simple technique is highly efficient but introduces
spectral distortion and artefacts. However, for many musical purposes, the distortion is not noticable... or may even be
useful when creating special effects!
Experiment with all settings to explore the behaviour of this versatille component. Note that you have full independent
control over the left and right channel equalisation. For example, the default settings in this DrawingBoard are different for
the left and right channels.
Note: if you need to perform accurate equalisation without adding spectral distortion, you can build elaborate equalisers
from WaveWarp's wide range of Digital Filters and Multi-rate components.
