Feature-by-feature
Splice is a content-and-licensing product. Its Sounds plan gives you 200 royalty-free sample downloads per month across 90+ genres, with unused credits rolling over — so a slow month doesn't cost you. Search and filter by genre, key, BPM, and pack. On top of that it runs rent-to-own across 130+ plugins at no interest, and you keep the full license at the end: Serum 2 at $9.99/mo, RC-20 Retro Color at $4.99/mo, V Collection 11 Pro at $24.99/mo, Abbey Road Two: Iconic Strings Pro. Splice INSTRUMENT is a separate $12.99/mo tier for unlimited preset access, and it now includes Spitfire Audio Originals and Craft plus free drops (an 808 instrument and a soft synth). The new Sounds Plugin is in public beta, bringing library browsing and downloading inside Ableton Live 12.3+, Studio Pro 8+, Pro Tools 2025.6+, and Studio One Pro 7.
MMAudio occupies a different category entirely. It's a diffusion-based generator that takes silent video and/or text and produces temporally aligned Foley and ambient sound — footsteps, door creaks, crowd noise. It ships as open-source MIT-licensed code with weights, a Hugging Face demo, a Colab notebook, and a Replicate API for online inference. It has zero sample library, zero presets, zero plugin licensing, and no DAW integration. One creates assets you compose with; the other generates audio tracks from footage.
Pricing compared
Splice is freemium with two paid tracks. Splice Sounds starts at $4.99/mo for 200 credits a month with rollover, so light users effectively bank unused downloads. Splice INSTRUMENT is $12.99/mo for unlimited presets, and you can also download it free and buy individual presets. Rent-to-own is a third spend stream layered on top: Serum 2 at $9.99/mo, RC-20 Retro Color at $4.99/mo, V Collection 11 Pro at $24.99/mo, Abbey Road Two: Iconic Strings Pro — all no-interest, with a full license transferring once payments finish. A producer stacking Sounds + INSTRUMENT + one rent-to-own plugin lands around $28/mo. MMAudio costs nothing. The code is MIT-licensed and the demos on Hugging Face and Google Colab are free; if you use the Replicate API for hosted inference you pay per usage on Replicate's terms, which is the only real cost line. The pricing models are not meaningfully measurable against each other: Splice monetizes content and licenses over time, MMAudio monetizes nothing and expects you to supply compute or an API budget.

Frequently Asked Questions
Can I use Splice samples in a commercial release?
Yes — the Sounds catalog is royalty-free, which is the core of what the subscription buys you. MMAudio is a separate question entirely: its output sits under an MIT license, but you should review third-party licenses before shipping it in a commercial product.
Do Splice sample credits expire?
Unused credits roll over into the next month, so a light month isn't wasted. That rollover behavior is why the $4.99/mo tier works for occasional downloaders.
Does MMAudio have a subscription or seat pricing?
No. It's free and open-source; the only cost is your own compute or Replicate inference usage. There is no library, no preset tier, and no rent-to-own program.
Which of these will generate a soundtrack for my video?
MMAudio will — it produces synchronized Foley and ambient audio from silent video and/or text prompts. Splice supplies samples and presets you arrange yourself; it does not generate audio from footage.
Is the Splice Sounds Plugin stable for daily work?
It's in public beta as of the latest release, so treat it accordingly before making it your only browsing workflow. It covers Ableton Live 12.3+, Studio Pro 8+, Pro Tools 2025.6+, and Studio One Pro 7.
Can I run MMAudio offline?
The MIT-licensed code and weights are published, so self-hosting is the intended path for developers. Hugging Face, Colab, and Replicate are convenience routes rather than requirements.
