Hi

I want build a multiband ( 10 band) 2-channel audio equalizer with FIR or IIR
filters. Can you suggest any sample project or ready library for that purpose ?

Regards,
Akin Ocal

Akin --

Go to freescale.com and search for two Application Notes, AN2110 (stereo 
10 band EQ with code for 563xx ICs). There is an earlier version 
covering the same application, but limited to 56xxx earlier chips and I 
don't have the APP Number handy/

Best

Just be aware that the graphic EQ in the freescale app note may not give
reciprocal boost/cut filter responses.  I implemented their grapic EQ from their
original app note APR2/D "Digital Stereo 10-Band Graphic Equalizer"
about 12 years ago and it worked but the boost vs. cut transfer  functions are
not reciprocal and therefore have different filter shapes (non-reciprocal
filters).  See my post about 2 months ago regarding how to derive reciprocal EQ
transfer functions.

Gene
