From R.M. de Boer Software:
SoundEdit Pro is a digital audio editor, designed for home studio recording and for people who are just getting started with audio editing. SoundEdit Pro has dozens of audio effects and tools for converting audio files into different formats, including MP2, MP3, WMA, WAV, Ogg Vorbis, VOX, and AIFF. In SoundEdit Pro, you can save the settings of each audio effect to a preset for later use. These presets are also available from the main menu, so you can execute them with one click of your mouse. Version 2.1.126 may include unspecified updates, enhancements, or bug fixes.
