Model terms
Generic terms equate Real-Time Pro license to the Attribution license, while product pages promote professional call-center use. Exact commercial terms and plan-specific overrides require confirmation; do not infer unrestricted output rights.Source for Model terms (opens in a new tab)
Creation privacy
Standard Real-Time Pro pricing says voice audio stays on-device without provider storage/access. Discounted and Free subscriptions consent to anonymized voice data for model improvement; cloud processing is extra. Generic terms also permit diagnostics/source retention. Do not extend local Standard promises to all plans, cloud processing or every service.Source for Creation privacy (opens in a new tab)

Deployment options
Windows/macOS virtual microphone; local CPU processing or separately purchased Altered cloud processing. Cloud pricing lists US, EU and India server locations; exact routing, choice and data residency guarantees unverified.Source for Deployment options (opens in a new tab)
Hardware requirements
How-it-works page: minimum six CPU cores, 8 GB RAM; Intel efficiency/low-power cores excluded. Recommends 8+ cores and16 GB. Windows10 build1903+, Windows11, or macOS11+ on Apple Silicon. Page labels requirements for Euphonia; other model performance must be confirmed.Source for Hardware requirements (opens in a new tab)
Model selection
Isolate Advanced is a provider model-family name in the Real-Time Pro app. App build freeze/rollback controls do not establish immutable neural checkpoints.Source for Model selection (opens in a new tab)
Documentation discrepancy
Isolate compares its output with MossFormer2 SE48kHz, described as non-streamable. A benchmark comparison is not evidence that Altered uses or owns MossFormer2 weights.Source for Documentation discrepancy (opens in a new tab)

Access & pricing

Prices belong to an endpoint and billing tier. A provider listing does not guarantee access for every account or region.

API model ID
Not collected

No callable public model ID or immutable checkpoint selector verified; UI names and voice-profile IDs are not API contracts.

Access
Licensed Windows/macOS virtual-microphone application. Use local CPU inference with a plan that includes the selected family. Download, biometric enrollment and performance were not tested.
Regions
Processing residency depends on deployment; no universal model-specific region guarantee verified.

Caching

Caching can reuse earlier input processing. Availability, lifetime and billing depend on the endpoint. A cache hit still generates a new response.

01 / INITIAL INPUTProcess & retain

The system processes eligible input and retains reusable state.

02 / LATER REQUESTCheck available state

Reuse depends on matching input, session state and the cache policy.

03 / CACHE HITReuse & generate

Reusing state can reduce repeated work. Any charges follow the billing rules below.

What the measurements say

No benchmark observations have been added for this model. We do not turn a vendor description into a performance score.

Latency and throughput depend on the host, request size, reasoning settings and load. There is no measured speed or global usage figure in this record.

The record behind the model

Why it is included

Provider identifies its own voice-model families and retains proprietary rights in application/voices, restricts source access and model redistribution. Commercial desktop availability does not make these open-weight releases. Individual speakers and presets are not new base checkpoints.
