AUTOMATIC EQUALIZER - Theo Medeiros - Jan 27 18:07:00 2005




I am trying to design an automatic equalizer using phase correction. 
The goal is to come up with a FILTER that can do phase correction 
over wide range of frequencies. Anyone has an idea of which filter I 
can use? Thanks.

Tee.

I thought of using adaptive filtering, but since it's a pahse coerrection. It might not be that easy. I plan on doing this using offline filtering. I just have to calibrate it once. Then I can play the CD/Audio component. I will need to write a linear IIR filter to correct the non-linear phase from the speaker. If you have an adaptive linear phase correction filter in mind, please feel free to share it. I would love to explore that as well. Thanks
