    Auto Equalizer

    Dear Paul & All in this Community,
    I have just received my Teensy 3.2 & became member of your family,

    I have a plan to make a project which will receive live audio from Microphone through ADC & correct the amplitude of different frequency of audio spectrum automatically & send output to DAC.
    What is the way & algorithm should be ?
    Please suggest me with your practical guidance.

    You would be using the audio library. If you have Teensyduino installed correctly

    Under files->examples->Audio you should have various examples that added together will be getting close to what you want.

    Various ways to do the filter process but the simplest is a bank of filter objects in the bands of interest.
