OFFICIAL PAGE: DeMIX Pro
DeMIX Pro, from AudioSourceRE, is an excellent application for upmixing mono source material to stereo. DeMIX Pro combines cutting-edge sound source separation capabilities with a built-in advanced spectral editor. DeMIX Pro includes both automatic drum and vocal separations as well as guided vocal and instrumental separations using a unique Melody Editor. Also included are automatic pan separation capabilities for use with stereo source material. In addition to harmonic selection capabilities, the spectral editor includes a number of intelligent spectral editing tools. A multi-channel mixer is included which allows you to quickly and easily listen to your separations in the context of a stereo mix. Level, pan, mute, and solo controls are available for each separated track. DeMIX Pro's Melody Editor allows you to manually identify the desired vocal or instrument that you wish to separate, even when in the presence of harmony vocals and other instrumentation. DeMIX Pro can also identify and separate the vocal's reverb and include it with the separated vocal if desired. DeMIX Pro performs its heavy number crunching in the cloud and is available for both macOS and Windows.
