TAS5713 GUI

Other Parts Discussed in Thread: TAS5713

Hi

I want to use the Equalizers in the chip for tone control of an Active speaker in real time. I can simulate my needs in the GUI but I don't see what register I need to change when I change the Gain on each filter. Do I have to calculate the Whole EQ function of the chip? If so can I get the equations how this software is generating the data for the EQ.

Thanks

Naftali

    Hi Naftali,

    There are upto 9 Bi-Quads available per channel on TAS5713, that are programmable independently (i.e. not required to calcualte whoe EQ function of all)

    As indicate in the block-diagram of the datasheet, these are are register's x29 through x2F & x58,x59 for left channel. Similaraly for the Right channel these are x30 through x26 & x5C,x5D. Note that each of these is a 20-byte register.

    Hi Ravi

    I will explain my question.

    I want to use the Bi-Quads for tone control. I simulate the needed filters in the GUI and I have saved the Registers setting via the GUI. But then I realized that this setting has constant gain and I  need to change the gain of the filters in real time, So my question is how do I find which register from the Bi-Quad  has the Value of the gain, OR how to calculate the Biquad parameters in real time. I didn't find in the data sheet the equations for the filters that exist in the GUI so if you can send me the source code of his PC software that make the calculations of the Biquad from the unput parameters like filter type , frequency , bandwidth etc. 

    Thanks
