Are the formulas for the coefficients available outside Cirrus' offices? I have a mac, and don't want to pay for a windows license + vmware (nor pirate them)

You can set the Parameters for the EQ Coefficients by the instruction

amixer${Bequiet} -D${Card} cset name='EQ1 Coefficients'

followed by the 38 decimal values comma seperated from the registers EQX_3 to EQX_21, you can easily generate the values with the wisce Software, but be careful, if the simulated eq curve not correct, the eq won't work, especially frequencies below 100Hz!

Marki555,

Have you had a chance to load the EQ registers? I looks like you would need to enter a string of 42 Hexadecimal or integer values for each of the Right and Left channels.

Have you produced a script for Playback using the EQ. I would be interested in what that looks like.

Thanks
