The best-documented of the three on licensing: its card links the Apache-2.0 text directly. Same loader and footprint as SOAR.
Summarized from the linked source documents, last checked 25 August 2026. Every claim links to its source; anything unconfirmed is marked unconfirmed.
Apache-2.0. Commercial use is permitted, with no revenue cap and no research-only carve-out. Keep the copyright and licence notices when you redistribute the weights.
Apache-2.0 asserts nothing over output. The card asks users not to impersonate, mislead or violate consent, and to disclose synthetic audio. These requests are advisory, not licence conditions.
Correction to the shipped catalog: The shipped catalog says "Unknown". This variant is Apache-2.0, linked from its own model card.
Based on the licence text as of the date below. Licences change; the links carry the authoritative version.
Transcribed from the shipped catalog, audiocpp_models_catalog.json — that file is authoritative if a number here disagrees with it.
audiocpp-dots-tts-mfdots_ttsThere is no per-model install. One native binary runs all of these, so getting a model is a download of its weights and nothing else — no virtualenv, no torch pin, no CUDA wheel to match against your driver.
soundbox model install audiocpp
soundbox pull audiocpp-dots-tts-mf<models dir>/audiocpp/audiocpp-dots-tts-mf/ rather than in the shared Hugging Face cache, so a download stays scoped to the model you asked for.Primary sources: the model's own repository, the project it came from, and the conversion audio.cpp actually downloads. Never invented — an entry with nothing findable says so instead.
Licence details on these pages are summaries of the linked source documents, last checked 25 August 2026. They are not legal advice, and Soundbox is not affiliated with any model's authors — weights download from Hugging Face under the user's own account and terms. Company and model names identify whose work it is, and belong to their owners. The linked licence text is authoritative; commercial use should be checked against it, per model, before anything ships.
