Upload your stems and get a finished immersive version back. GravityLLM places each track around the listener in 3D, and our agents deliver ADM, Eclipsa Audio (IAMF), binaural, and Ambisonics files in minutes - not days.
Music is available now · Plans from $0, Pro $29/mo
Upload separate stems for vocals, drums, bass, guitars, synths, strings, brass, and any other instrument. Each element receives its own precise spatial positioning, elevation, distance, and dynamic movement automation in the 3D soundfield.
GravityLLM, the Spatial9 model trained on how sound should be arranged in space, listens to each stem and places it following genre conventions and professional mixing practice.
Listen to your immersive mix on ordinary headphones with binaural rendering and review it before you download the final deliverables.
Because stems are already independent, each one moves to its own position around, above, and behind the listener instead of collapsing to one point.
Export ADM for professional workflows, Eclipsa Audio (IAMF) for YouTube, binaural for headphones, and Ambisonics. Available formats depend on your plan.
Add movement to any stem - cinematic pans, orbits, height sweeps, and proximity shifts that evolve with your music. Advanced movement is included on the Studio plan.
Start with AI-generated spatial layouts optimized for your genre. Electronic, hip-hop, rock, classical, jazz, ambient - each has distinct spatial conventions that GravityLLM understands and applies.
Spatial9 detects musical sections (intro, verse, chorus, bridge, outro) and can apply different spatial treatments to each, creating dynamic mixes that evolve and breathe with your arrangement.
Traditional spatial mixing means learning panners and renderers or weeks of back and forth with an engineer. Spatial9 delivers a finished, publish-ready mix on its own.
Create immersive mixes without a speaker array, room treatment, or specialized monitoring. Review everything on headphones with binaural preview.
Every mix follows established spatial audio standards and psychoacoustic principles. AI-assisted positioning eliminates guesswork and ensures your spatial choices enhance rather than distract from the music.
GravityLLM understands that a jazz trio needs intimate positioning while an EDM track benefits from expansive, dynamic movement. Our research was presented at the AES Show 2025.
Try it on the Free plan, then move to Pro at $29/mo for 5 projects a month with all export formats, or Studio at $149/mo for 30 projects and advanced movement.
Get ADM, Eclipsa Audio, binaural, and Ambisonics versions from the same upload, depending on your plan. Eclipsa Audio files are ready for YouTube.
Spatial9 enhances your vision rather than imposing one. The mix keeps the sound of your stems while adding depth, height, and space around them.
Process single tracks or entire albums with the same workflow. Teams can submit in batches, track job status, and integrate through our API and webhooks.
