SoundEngine Free is a simple, two-channel program for processing PCM WAV tracks, designed primarily for mastering. Free version provides only the basic functions of importing and recording sounds, at the same time it offers a rather long list of effects (more than 30), which can be used during further processing. Unfortunately, it cannot handle more than one path at a time.

There is also no possibility to expand the program with additional plugins and effects. The program has, among others, a spectrum analyzer and a signal level meter. SoundEngine does not require installation - which is an advantage or disadvantage, depending on preferences.
