TLV320AIC3120: Needs more information about Purepath AGC Component parameters

Part Number: TLV320AIC3120

Hi all,

I am working on TLV320AIC3120 custom board. For audio processing I am using Pure path studio. In that I am interested to use dynamic processing block AGC provided after mic input. But in the help file of AGC explanation about configurable properties not enough to calculate parameters according to my application requirements. So is there any resource available where I can look into to gain some more information about it?

Let me know.

Thanks,

Regards,

Krushna Manjarekar.

Hi,

This application note explains about the internal AGC parameters. If something related to the AGC component parameter which is available in PurePath studio will be helpful. Like formulas to calculate those coefficients (AGC Desired level, min audio, min gain, max gain, etc).
