I am following this link from instructable site..

http://www.instructables.com/id/Arduino-Audio-Input/

My question is,

Instead of using the Microphone Radioshack 33-3038, which is listed in the tutorial , can I use https://www.sparkfun.com/products/9964,

Kindly suggest is there any modifications required in other parts for the circuitary If I go for Electret Microphone .

The replacement microphone you link to contains all the circuitry in that instructable*. You can do away with the op-amp and all the associated stuff, and just connect it direct to the analog input of the Arduino.

*Actually it's better circuitry since they do it right, unlike the Destructable that is a rubbish circuit.

Destructable! Awesome! –  Gerben yesterday
    
@Gerben 90% of what is on Instructables is complete and utter garbage. The other 10% is my comments telling them so ;) –  Majenko yesterday
    
one more query guys, As sparkfun Electret microphone has already inbuilt op-amp, So do I need to discard op-amp circuitry in instructable site or just proceed with op-amp circuitry ? confirm me. –  ferraro yesterday

Discard it. As I said in my answer, connect it direct to an analog input. –  Majenko yesterday
    
Thanks Majenko As you suggested I made a connection to A0 and I can see I was able to get the frequency values as my output, But I can see code is not stable at all, So could you suggest me is there any good reference code or any blog which can help me out to get the frequency hz values as my output when I connect electret microphone to arduino. –  ferraro 12 hours ago
