What it is
AudioStem.ai is a web-based tool for making AI songs, separating audio into stems and mixing them in a browser. Its separation options include four- or six-stem models and parts such as vocals, drums, bass, guitar, piano and karaoke. The mixer can keep stems synchronized and offers A/B loops, individual volume, mute and solo controls, a 10-band equalizer, effects and custom mixes. Uploaded files can be MP3, WAV, M4A, FLAC, OGG and other common formats, with tracks up to 90 minutes. Pro adds BPM, key and chord detection; Studio adds a metronome, key control and pitch-preserving speed adjustment. Pro and Studio users can generate songs up to five minutes long, with two versions per charge. All plans download MP3, while Pro and Studio also offer WAV, MIDI and custom-mix exports. The free plan has no downloads or share links. Paid plans start at $7.99 a month. AudioStem.ai says uploaded audio is used to make stems, not train models, and is not sold or shared with model vendors.
