AudioMint, from Zerebrix, is a standalone application for separating vocals and accompaniment sounds. According to their website, "AudioMint not only separates vocals and accompaniment sounds, but also reconstructs and recovers damaged or missing audio using the power of AI. Audio sources are damaged during mixing due to phase interference, but AudioMint identifies the damage and seamlessly reconstructs missing audio pieces so that the result sounds just the same as the original source." AudioMint is available for both macOS and Windows. Full details at the link above.
