Soundstripe single-use licenses at $49, $199, $399 vs AI music

Soundstripe's single-use licenses start at $49 for Personal use and reach $199 for Digital, $399 or more for Expanded, and $1,249 or more for All Media, according to its pricing page read today. A generated track on Sume costs $0.125 per accepted generation. The two numbers are not interchangeable: one buys a right to use a specific song for a stated purpose, the other buys a new file whose usage terms you must confirm separately.

If your question is "what does it cost to put music under one ad?", the library answer is a license tier and the Sume answer is a render plus a generation. The honest comparison is about how many ads you make and what each one needs to be cleared for.

The tiers, as listed (read 2026-10-05)

On Soundstripe's pricing page the single-use licenses are listed by purpose. Personal covers social media, blogs and personal events. Digital covers podcasts, ads, film festivals and client licensing. Expanded covers corporate use, out-of-home advertising and events. All Media covers TV, radio, theatrical and streaming services. The same page lists subscriptions from $9.99 a month, with 58,000+ tracks and 115,000+ sound effects, and stems for original songs on the Pro tiers.

Arithmetic that is fair, and arithmetic that is not

Ten ad variants each carrying their own Digital license would be 10 x $199 = $1,990, while ten generated beds are 10 x $0.125 = $1.25. Do not read that as a saving. It is only a saving if the generated beds are cleared for your use and the library tracks would each have needed a separate license. A single Digital license may well cover several cuts of one campaign; the page does not say, so ask Soundstripe.

What the numbers do show is the shape of the cost. A license price scales with the use you declare. A generation price scales with how many tracks you ask for.

There is a second shape worth noting: the subscription. Soundstripe lists plans from $9.99 a month with unlimited access, which turns the per-use license into a flat monthly cost if your use fits the plan. For a studio that makes a handful of ads a year, a single-use license is cheap. For a team shipping dozens of variants a week, the monthly plan or a generated bed per variant is the cost that scales sensibly. Work out which of those you are before comparing prices.

Where Sume fits next to a library

Sume does not sell a catalog or a license tier. The Music Router docs cover one thing: a prompt in, an MP3 and optional lyrics out, on Google Lyria 3.5 today. Length is steered in the prompt because the router rejects duration and duration_seconds, and a non-empty negative_prompt returns a 400. The Timeline docs then handle the mix: soundtrack.loop, fade_out_seconds up to 10 and duck_db 0 to 20 under a spoken spine, at $0.10 per started output minute.

Before you buy either

Write down the media the ad will run in, the territory, and whether a client will own the final file. Then ask each seller, in writing, whether that use is cleared. For Soundstripe the tier names above are the checklist. For Sume, no usage statement appears in the docs read for this post, so the question goes to Sume. Keep the answer with the job id and the prompt for each track. If a client asks later how a bed was made, those three items (the question you asked, the answer you got, and the job record) are the whole file you need.
