What it is in one line
Not another sample-pack site, but a free AI sample library where the loop you cannot find is the loop you generate yourself — and every generation lands in a public library for the next person.
Who built it
An ElevenLabs product (elevenmusic.io), posted to HN by ElevenLabs' Oslo employee Sigve Sebastian Farstad (sigvef). Per ElevenLabs' own blog, it is the free sounds-and-loops library for ElevenMusic, with material generated by ElevenLabs' music model.
Read: a big AI-music company shipping a free sample library is usually not trying to make money on samples. It is trying to make "generate the sound you want" a habit, and feed its own model with the usage.
What it actually does
- Free browsing and downloads of AI-generated samples and loops — vocal chops, drums, bass, melody, foley and more, tagged by BPM, key and style
- Cannot find it, generate it: describe the sound in text and produce it; there is a daily free allowance
- Generate-and-archive: every generation joins the public library, so the catalog grows with use
- Links into ElevenMusic: a loop can "turn into a full song" directly
What it deliberately does not do: no exclusive paid packs, no licensing lock (everything is marked royalty-free). It is the free entry point to the ElevenLabs music ecosystem.
What old behavior it replaces
The sample-pack economy: subscribe to Splice or similar, spend hours hunting through packs, then worry about licensing. One HN commenter literally recalled "spent sooo much time and effort scavenging for loops and sound effects."
The old workflow's core friction: the chance that the exact sound you want exists in some pack, in the exact tone you want, is low. Sounds reverses the flow — cannot find it, generate it; the result goes into the public library, and the catalog gets fuller the more it is used.
Business model
Free. Browsing, previewing and downloading are open to Free / Pro accounts, plus a daily free generation allowance. No separate pricing disclosed.
Read: this is clearly an acquisition layer for ElevenLabs, not a profit layer. The free allowance builds a usage habit that funnels into paid ElevenMusic generation credits; the public library fills the catalog with user-generated material, saving ElevenLabs the cost of curating one.
Hard numbers

| Founder-product fit |
The poster is a music producer who also works at ElevenLabs; the pain is real, but this is a company project |
| Product insight |
Nailed "cannot find the sample" as a frequent frustration, replaced search with generation, and recycled UGC back into the catalog |
| Execution quality |
Built on the ElevenLabs music model; the quality bar is out of reach for an indie |
| Timing |
Right now. Music generation just entered "good enough" territory, and a sample library is its first natural landing spot |
The call
This is a small specimen of the shift from search-based to generation-based asset consumption.
The old model starts with a catalog and demand is bounded by it; the new model makes demand the catalog — every "cannot find it" is a demand signal, and the generation becomes supply. The public library is the load-bearing design: it turns one user's single generation into an asset for everyone.
The transferable rule: if your users keep "searching" for something, let them "make" it instead, and sink the results into a shared asset pool. The search cost is your content team's; the making cost is split between the model and the users.
The cost and the problem: catalog quality depends on user output, so expect many homogeneous, low-quality entries; and this only works at ElevenLabs' scale. An indie can copy the mechanism, not the model.
What to watch next
① Whether public numbers appear for catalog growth and the "cannot find → generate" conversion rate
② Whether ElevenLabs tightens Sounds to paid Music credits — a shrinking free allowance would mean the funnel is working
③ Whether other AI music makers (Suno, Udio) follow with free sample libraries — following would confirm the funnel works
What you can take from it
Product logic: "cannot find it, generate it, and put the result in the library" — turn a user frustration into your content supply and let the catalog grow at zero marginal cost. Applies to any content- or asset-centric product.
Pricing structure: none. Free, not disclosed.
Verdict
Write it down, do not act yet. The mechanism (generate-and-archive) is transferable to content products, but it is one piece of a big company's ecosystem; an indie cannot copy the supply side. In three months, check whether the public library is still growing and whether Suno has followed.
