1.2 About This Application

Nero WaveEditor allows you to record music, and edit the respective audio files using various filters and sound enhancement methods. You can then burn these optimized audio files using Nero Burning ROM or Nero Express.

Nero WaveEditor allows you to edit the audio files in real time without damaging the original file. Thanks to an internal reference-based audio format, the editing history is also saved so that changes can be undone. Various effects (e.g. chorus, delay, flanger, reverb), numerous tools (e.g. stereo processor, equalizer, noise gate), sophisticated improvement algorithms (band extrapolation, noise suppression, declicker) as well as various filters and tools in Nero WaveEditor assist you in editing your files.
