My oS is win 7 prof 64 bit and i have the above software. When i make a recording using my mike from the pc's speakers, i am able to save it as a wave file. how the capture looks like is given in the attached file. If u notice the waves are highly concentrated, and thus for me to precisely edit it is a challenge. How can i spread out the waves so that i coudl either insert marker or precisely edit the file.
