Wavepad

WavePad is an interesting application which allows you to make multiple changes on your audio files. Using it, you will be able to copy, cut and modify an audio file as you want.

The graphic representation of the sound makes easier your work. Some of the actions you can perform are amplification, normalization, equalizer, echo, fade in, fade out, noise reduction, etc. It also allows you to change the timing and tone by three different ways.

WavePad includes other tools which are very interesting, some of them are not available at first time, but you can download them for free from the official site.

It supports WAV, MP3, WMA, VOX, GSM, AU, RM and more.
