Schematics

the circuit diagram for active noise cancellation.

there are two microphones used in this circuit one is the microphone which recognise the sound and other is the error microphone with speaker which produces the amplitude and frequency which is observed by the microphone is that it gets collide and it gives us the output as noise cancellation.

Code

noise cancellation

in this code we are using adaptive algorithms which are of two types one is least mean square algorithm and fxlms and adaptive filters.
