Do any one have any audio limiter circuit for the headset. I have design headset audio circuit so i need to design a limiter ciircuit so that the audio level stays constant and doesnt cause ear damage
Have a look at an example of an audio compressor: **broken link removed**

Forget about the DA converter. You can replace it with a potentiometer to adjust the level ..
