Audio Editing support for Dell 11 3147

Sir

I have the Dell 11 3147 Laptop running by Windows 8.1 and the system is well within warranty.

Now I urgently need to install the Driver & Software for editing the Audio Filed of my system which has been recorded by my Laptop itself. I failed to find ways for editing the audio files.

Matter is most urgent for me.
