Equaliser based on approximate brick-wall filtering
Illustrates the use of the Brick-wall 8-band Equaliser block for performing 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: 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.
