DramaBox

Commercial use: conditions applyLTX-2 Community License Agreement

Heavier than every other voice model here. DramaBox is a fine-tune of Lightricks' LTX-2, so the weights carry the LTX-2 Community License, although Resemble published the model and the inference code is MIT. That licence has the most output-side obligations of any in this catalog.

The licence

Summarized from the linked source documents, last checked 25 August 2026. Every claim links to its source; anything unconfirmed is marked unconfirmed.

LTX-2 Community License Agreement

Commercial use: conditions apply

Free commercial use below $10,000,000 in annual revenue. At or above that you are a “Commercial Entity” under the licence and must obtain a paid commercial licence from Lightricks. If you do not, liquidated damages are set at double the fees owed. The licensor is Lightricks, not Resemble.

Conditions

Entities at or above USD $10,000,000 annual revenue must obtain a paid commercial licence from Lightricks.
Attachment A carries roughly twenty use restrictions (harm to minors, false information, impersonation, automated decision-making, discrimination, malware, military, competitive use), and downstream agreements must pass them through.
The inference code is MIT, but the weights are what carry the LTX-2 terms.

What about the audio you generate?

Three constraints on what you generate. Machine-generated content must carry an "expressly and intelligibly" stated disclaimer that it is machine generated. Outputs may not be used to train, improve or fine-tune any other machine-learning model, other than LTX-2 derivatives. And every output of the upstream inference path is watermarked with Resemble Perth by default.

Correction to the shipped catalog: The shipped catalog says "Unknown" and lists the vendor as "Unverified". It is the LTX-2 Community License, and the licensor is Lightricks Ltd. DramaBox is an adapter fine-tune of Lightricks' LTX-2, published by Resemble AI.

Getting it

There 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.

From the CLI

soundbox model install audiocpp
soundbox pull audiocpp-dramabox

The binary is fetched from audio.cpp's GitHub releases the first time you ask for it and cached under your own data directory. Soundbox ships no native binaries and vendors none.
Weights land in <models dir>/audiocpp/audiocpp-dramabox/ rather than in the shared Hugging Face cache, so a download stays scoped to the model you asked for.
This one is opt-in: switch it on in the Models page's “Enable more models” section before it appears in the picker.

Worth knowing

~21 GB of VRAM. Only the MiniMax H3 entry asks for more.
Opt-in and untested here.

Sources

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.
