Need help in the project "Arduino for audio processing" I am following this link from Instructables 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 if there any modifications required in other parts for the circuitry, 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.
