STEM review
A focused web workspace for sharing, discussing, and reviewing music stems.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
STEM is a web-based collaborative audio mixing platform for bands, musicians, producers, and other music collaborators. It centers on uploading audio stems, mixing them in a multitrack workspace, discussing changes, and sharing songs for review. Timed comments can be attached to songs or individual tracks, while secure share links provide customizable permissions. The product is suited to remote creative review and decision-making, especially when collaborators need a shared place for mixes, notes, lyrics, charts, and reference files without replacing a full digital audio workstation.
Its feature depth is concentrated around review and iteration. Real-time project collaboration, mix snapshots, and MP3 mix rendering support a practical discussion cycle, while song attachments keep supporting material alongside the audio. Lists and setlists add organization for collections of songs. The published feature set also includes permissions for shared projects, which helps separate collaborators from broader listeners or reviewers. Version history is limited, so teams that need extensive archival comparison or a detailed production timeline may find the workflow less suitable.
According to the vendor’s pricing information, STEM offers a free-forever plan, while the available product details do not define paid-tier scope. The platform is available on the web, and its integration coverage is limited. That makes STEM a focused choice for musicians and producers who want straightforward stem sharing, timed feedback, and collaborative mix review in one browser-based space. Teams looking for a full production environment, broad platform coverage, extensive version control, or a wider integration ecosystem should consider an alternative built around those requirements.
