Will filtering a signal through multiple bandpass filters, where each filter is passed the complete signal, and then combining the output have the same result as a parametric EQ?
What if the signal is passed into a series of bandpass filters?
Are there any performance issues or optimizations that can be made when EQing a signal this way?
After reading the answer in this question which-filter-for-an-audio-equalizer it seems splitting the signal through a filter bank (in parallel) is the correct way.
The answer explains how the bands need to blend together to avoid audio issues, how is this calculated if each bandpass filter can have a varied bandwidth?
