I do not want mid and treble.
because I have to use your microphone
s letter-letter z - such as the high-frequency very bad.
please help me. thank you very much.

I'm not sure what you are asking exactly but if you just want bass range frequencies then you just need to add a low pass filter to the input of the code.

frank
but I do not know
how do
please write
my code Edit
please
thank you very much

Have a look here http://www.spinsemi.com/knowledge_base/ ... .html#WRLX

and here, which shows the formula for calculating the coefficient to set the corner frequency.

input where?
I do not know
my english very bad
I can not
We produce audio & guitar amp mixer

thank you very much

OK, if you are a manufacturer then you should be able to get help from the distributor you are getting the parts from. They should be able to help you modify the code to fit your needs.
