Adau 1467 6Band eq

Hello,

I will be able to create a project and send it to you if you can give me some details.

which block you are trying to use and what is the parameter you want to control from the pot?

Are you looking for an index selectable filter and want to select the filters with the pot?

There are a lot of projects in the forum with pot and eq control.

Please give me some info to assist you further.

Regards,

Harish

hello I need the sematic for adau1467 the bands should be

low shelf 45hz
Parametric 63hz
Parametric 240Hz
Parametric 400Hz
Parametric 800Hz
high shelf 6000hz

controlled with a potentiometer

I've tried something myself but it always cracks when turning

one potentiometer for each frequency

changeable -12 to 12db

Hello Lorenzo4711,

I can quickly think of a project with the Holters filter. Almost every filter block in sigma studio, you can't control a parameter individually since it is involved in the coefficient calculation. The gain value is also a part of the coefficient values. So, you can't control the gain parameter individually, all you can do is to calculate new coefficients for the new gain (sigma studio calculates and downloads it into the DSP as you change in the GUI).

However, this holters filter has an external control over the gain. Hence you can control it from a pot. I attached a project with 5 bands and gain will be controlled by 5 auxadc's. The logic for the gain limitation with auxadc's outputs are implemented in the hierarchy boards.
