Wavepad

WavePad is a very interesting program that can make multiple edits to your audio files. With it, you can copy, cut, and modify an audio sequence however you like.

The graphical representation of the sound waves makes it much easier to work with the files. Some of the changes that can be made are: amplify, normalize, equalize, reverb, echo, fade in, fade out, envelope, reduce noise, etc. You can also change the speed and pitch of an audio sequence in three different ways.

WavePad also includes AI-powered tools such as noise reduction, audio enhancement, voice editing, and text-to-speech to help improve audio quality and speed up common editing tasks.

You can use WavePad as a tone generator, a voice synthesizer, and a text-to-word tool. With this program you can also create predefined sets of actions to simplify working with multiple files.

Supports over 50 audio formats including MP3, WAV, FLAC, OGG, AAC, M4A, WMA, VOX, GSM, AU, AIFF, AMR, MID, and many more. It supports samples from 6 kHz to 192 kHz, in stereo or mono, and in 8, 16, or 32 bits.
