For an AI-powered platform that can rapidly and accurately separate audio tracks into stems, AudioShake is a good choice. It's geared to extract stems from audio recordings, but it can be used for a variety of tasks including mixing, mastering, localization and captioning. It accepts files up to 192kHz and offers several entry points, including AudioShake Live, AudioShake Indie and an API for deeper integration.
Another good option is Cryo Mix. The platform offers AI-powered mixing and mastering tools, but also includes an AI Audio Separator that separates stems like vocals, drums and instruments from a single audio file. It also offers pitch correction and final mix preparation, so it's accessible to anyone who wants to improve their audio.
LALAL.AI is another option. It lets you separate audio files into high-quality vocal and instrumental tracks, and it works with a variety of stem options and with multiple file uploads. That makes it good for musicians, streamers and others who need reliable stem separation. The company offers other tools, too, including a Voice Changer feature in beta testing.
Last, Samplab is a tool geared for music producers and DJs. It lets you manipulate and improve audio samples with tools like polyphonic audio editing, chord detection and stem splitting into instrumental, drum, bass and vocal tracks. It's available as a VST3 and AU plugin or desktop app, and Samplab offers flexibility for different workflows with free and premium versions.
