Audacity

Have you ever felt the need to edit audio or music and can't seem to find the perfect free software to do so. Yes WavePad is fine to use but it is not free. Therefore here is a software for this particular purpose. Its free, its light and its Audacity. Audacity is available for both Windows and Mac. It does not have so many features as Audition or Sound Forge but it has all the basic features for audio editing.
