Spherify

Turn any stereo master into an editable immersive mix — no original stems required.

Developer: Sonus Immersivus · Format: Standalone application (macOS & Windows) · Category: Spatial / Immersive Audio · Stem Separation · Mastering & Post-Production.

Short Description

Spherify is a spatial-audio production tool for macOS and Windows that transforms stereo tracks into editable immersive projects. It uses on-device AI to separate a stereo mix into musical stems, places those stems as objects in a 3D sound field, and lets you preview, edit, automate and export delivery-ready spatial audio — including ADM BW64, IAMF and MPEG-H.

Description

Spherify closes the gap between a finished stereo master and a modern immersive release. Instead of rebuilding a spatial mix from scratch — and instead of hunting for original multitrack sessions that may no longer exist — Spherify starts with the material you already have: the stereo file.

Drop in a stereo track and Spherify separates it into musical stems using Demucs running natively on Apple MLX, so the AI step is fast, local, and free of cloud costs or per-track fees. Each stem becomes a true spatial object that you place in three dimensions by azimuth, elevation and distance. There are no fixed channel assignments — the scene is pure object-based authoring from the first pass onward.

From there, the project stays fully editable. Work the timeline with waveform views and stem slices, draw automation lanes so objects move and evolve over time, and — at the Pro tier — apply per-object plugins to shape individual stems before they render into the spatial layout. Preview the result in real time as you refine placement and processing, then export to the spatial formats that matter for broadcast, streaming and cinema delivery.

Spherify is built for music producers and artists releasing in Apple Music Spatial Audio and Amazon Music HD, for labels converting back-catalog stereo masters to immersive at scale, for post-production and dubbing studios working from stereo deliverables, and for spatial-audio engineers who want a fast stem-to-object starting point before final refinement. It is a practical bridge from stereo catalog material to object-based immersive delivery, in one connected workflow.

Key Features

• Stereo-to-spatial in one workflow — import a stereo file and reach a credible immersive starting point in minutes, then keep refining.
• On-device AI stem separation — Demucs runs locally on your machine (hardware-accelerated via Apple MLX on Apple Silicon). Fast, no cloud and no per-track API cost.
• Object-based spatial mixing — every stem becomes a 3D object with full azimuth, elevation and distance control. No fixed channel assignments.
• Timeline & waveform editing — waveform views, stem slices and detailed arrangement editing over time.
• Automation lanes — animate object position and level for evolving, moving immersive scenes rather than static upmixes.
• Stem slicing — break stems into instrument-focused regions for more detailed scene construction.
• Per-object plugins (Pro) — apply creative or corrective processing to individual objects while keeping the scene editable.
• Real-time preview — hear spatial changes as you work against your renderer configuration.
• Professional spatial export — ADM BW64 and IAMF (Standard+), plus MPEG-H import/export (Pro), covering broadcast, streaming and cinema pipelines.
• Batch & playlist workflows — process multiple sources for catalog-scale and production-volume work.

Tiers

Free — Evaluate the core workflow. Create up to 6 stem-separated projects from one stereo source at a time using the platform's free 6-stem separator, and explore the resulting spatial projects.

Standard — The main production tier. Adds persistent project editing, multiple-source import and append, timeline editing, waveform slice editing, stem slicing, automation, fast preview, Save Project As, ADM BW64 export, and IAMF import/export (where supported by the build).

Pro — Everything in Standard, plus per-object plugin support, MPEG-H import/export (where supported by the build), feature updates, model updates, and support tickets.

System Requirements

• macOS (Apple Silicon, with Apple MLX-accelerated AI inference) and Windows.
• Standalone application.
• Spatial export formats: ADM BW64, IAMF, MPEG-H.
