WavePad Audio Editor Software is an audio and music editor for Windows and Mac (also available for iOS and Android). It lets users record and/or edit music, voice and other audio recordings. As an editor, users can cut, copy, paste, delete, insert, silence, and auto-trim recordings, then add effects like amplify, normalize, equalize, envelope, reverb, echo, reverse, and more with the help of VST plugin support and a free stock audio library.[1]

NCH Software claims over 18 million users of the product, and as of March 2016, WavePad is listed as having over 4 million downloads on CNET's Download.com [2]


The primary functions and tools of WavePad are:[3]

  • Sound editing functions: cut, copy, paste, delete, insert, silence, auto-trim and more
  • Audio effects: amplify, normalize, equalize, envelope, reverb, echo, reverse and many more with VST plugin compatibility
  • Batch processing allows users to apply effects and/or convert thousands of files as a single function
  • Scrub, search, and bookmark audio to find, recall and assemble segments of audio files
  • Spectral analysis (FFT), speech synthesis (text-to-speech), and voice changer
  • Audio restoration tools including noise reduction and click pop removal[4]
  • Supports sample rates from 6 to 96 kHz, stereo or mono, 8, 16, 24 or 32 bits
  • Remove vocals from music tracks[5]
  • Create ready to use ringtones for mobile phones[6]

Use in Education[edit]

As indicated by author Victor C.X. Wang/Florida Atlantic University in his book Handbook of Research on Education and Technology in a Changing Society,[7] WavePad's Free Trialware Version is more than adequate for educational institution use. WavePad is linked or referenced for download on many notable university websites for students requiring complex audio manipulation[8] (note 2016 WavePad is now a Free Trialware Version). NCH Software offers Academic pricing.[9]


Previously, WavePad and other NCH products came bundled with optional browser plugins like the Ask and Chrome toolbars, which sparked complaints from users and triggered malware warnings from antivirus software companies like Norton and McAfee. NCH has since unbundled all toolbars in all program versions released after July 2015.[10]
