TAS2505: TAS2505 EQ settings

Part Number: TAS2505

Hi Audio expert,

        One of my customer is using the TAS2505. I found it integrate the audio processing function, but i didn't found any button which are related with EQ setting in TAS2505 GUI software. So my question is how to set the EQ in TAS2505. I also referred the TAS2505 application note, there are some sample code, that i found we already provide the coefficients to get some specific filter. If the customer want to get the other specific filter, how to calculate the coefficient. Could we provide tools to get it? Thanks. 

 

        

  • HI Gary,

    You can use the TIBQ application, this is a Coefficient Calculator for Biquad Filters. You can setup the filter response using the graphic interface and obtain the coefficients. Then you just need to add this coefficients to your initialization script:
