LoAIR from Waves is a plug-in for generating and enhancing subharmonic content in music or sound effects. The process adds heft and depth to audio material, while also allowing the shaping of the ultra low-end with adjustable frequency and low-pass filter controls. Additionally, the software can process polyphonic content in a manner that enhances the low end in a natural and musical way, as well as create an LFE track from stereo or 5.0 sources.
