Couldn't listen to your sound bite yet if the noise is completely out of the ordinary then it most definitely is a sign of a problem.

Mio, your statement made it sound like the sound goes away after a few minutes? A few culprits could be:

Power steering pump. (check fluid level)
AC compressor.
Alternator.
Belts.
Idler pulley.
Transmission (hopefully not.... - check fluid level)

Pop the hood next time and attempt to locate the "area" the sound is coming from. If from the right/passenger side of the engine compartment it most likely is associated with the drive belts/accessories etc.. If on the left/drivers side then that could mean transmission or possibly just a leak in your CAI.

Keep us posted - good luck

 

Timing belt or AC belt.
