53,000 sound effects listed from €60,000: what an audio owner must show
A public AI-training listing asks €60,000, labeled as a starting price, for a one-off purchase of more than 53,000 sound effects. That is an asking price for one defined library, not a paid deal and not a per-file rate for every archive. Before a price conversation, an owner needs counts, rights and metadata a reviewer can check.
If you own a sound-effects library, a production-music catalog, stems or MIDI, you may have searched for what that audio is worth as AI training data. Few sellers publish a price. Several large audio libraries that offer AI licensing publish their volume but no price, and ask buyers to contact them.
The few public prices are useful if you read them for what they are: an asking price, an advance or a published licensing model, each for a specific package of files and rights. None is a rate you can multiply by the size of a different catalog.
For this Market Note we read public listings, licensing pages and filings captured on October 27, 2026. They show what is priced in public and what an owner should prepare. They do not establish what any catalog will earn.
One sound-effects listing publishes three prices
On Datarade, a data marketplace, Krampfstadt Studio lists a catalog of "over 350 premium libraries, comprising more than 53k individual sound effects." The listing states a volume of 53,000 sounds in .wav format, "delivered mostly in 32-bit float / 192 kHz," with Universal Category System (UCS) file naming and embedded WAV metadata.
| License on the listing | Asking price | Plain arithmetic |
|---|---|---|
| One-off purchase | €60,000 / purchase | €60,000 / 53,000 files = about €1.13 per file |
| Yearly license | €20,000 / year | €20,000 / 53,000 files = about €0.38 per file per year |
| Monthly license | €3,000 / month | 12 × €3,000 = €36,000 for twelve months |
| Usage-based | Not available | None |
Source: Krampfstadt Studio's listing on Datarade, checked October 27, 2026. The listing is undated, and its prices sit under the label "Starts at." These are asking prices, not paid amounts. The listing says "more than 53k" files, so at the listed price each per-file figure is an upper bound.
The one-off price is three times the yearly fee (€60,000 / €20,000 = 3). Twelve months at the monthly starting price, €36,000, cost more than the yearly license.
Why one library's price does not scale to a larger one
The per-file arithmetic is tempting: divide the price by the files, then multiply by your own count. The listing gives no basis for that. It marks "Usage-based" licensing "Not available," publishes no volume tiers, and asks buyers to "get a quote and arrange custom pricing models based on your data requirements." It states no exclusivity terms and no limit on models or use.
So €1.13 is the arithmetic of one catalog at one asking price. A buyer of a far larger catalog may need only some categories, may already hold similar material, or may want terms this listing does not state. That price is set in a negotiation about scope, not by multiplication.
Large libraries publish volume, not price
Other sound-effects and music sources state what they offer for AI and machine learning use, and leave price to a conversation.
| Publisher | What the page states | Price shown |
|---|---|---|
| Sound Ideas | 1.4 million sound effects in 675,000 files, 1,400+ hours of audio, "All files embedded with detailed metadata" | None; "Contact us to learn more about custom licensing solutions" |
| Soundsnap, on Datarade | 800,000 sound effects and 50,000 tracks "for machine learning and generative AI" | "Soundsnap has not published pricing information for their data services." |
| Depositphotos, on Datarade | An audio and SFX collection of 3M assets, with one-off, monthly and yearly licenses marked "Available" | "Request detailed pricing" |
| Unidata | 500,000 sound-effect audio files | None; the page offers "Get in touch" |
| XIM Audio, on Datarade | 63,000+ stems from 2,819 tracks, 12,426 DAW sessions and 338,853 MIDI files, among other sets | "Pricing available upon request" |

A missing price says nothing about value. What these pages publish is a description: counts, hours, categories and metadata. That is the part an owner controls.
Music packages price the license, not only the files
The clearest public music prices are for small packages. Tone Cube Media sells a mini dataset of original instrumental music at 96 kHz / 24-bit, with "5 full mixes and 15 consolidated stereo stem files in total," built from one seed composition. The same 20 files carry different prices depending on the license.
| Offer | Asking price | What the license allows |
|---|---|---|
| Evaluation license, on Gumroad | $149 | "internal commercial evaluation, benchmarking, compatibility testing," and R&D |
| Production license, on Gumroad | $249 ($149 base plus $100) | Non-exclusive, worldwide and perpetual, for "commercial model training, fine-tuning, weights generation, and commercial deployment" |
| Listing on Datarade | Starts at $199 per purchase | Evaluation and internal R&D; "Production deployment and commercial model training require a separate commercial license." |
Source: Tone Cube Media's Gumroad product page and Datarade listing, checked October 27, 2026. The pages are undated. These are asking prices, not paid amounts.
On Gumroad, the production license costs $100 more, about 1.67 times as much ($249 / $149). Buyers pay for what they may do with the files: evaluation is priced apart from training a commercial model. This is one 20-file package, so its per-file arithmetic does not carry over to a catalog of thousands of tracks.
Per-track figures are advances and estimates, not prices
Neither per-track number below is a verified price that an AI developer paid for a track.
LANDR, a music distributor, runs an opt-in program that licenses its artists' tracks for AI training. It offers "an upfront recoupable advance of $5 per eligible track," with artists "earning a 25% share of net licensing revenue." If the advance is recouped from the artist's 25% share, a track needs $20 of net licensing revenue ($5 / 25%) to earn it back. Artists who take the advance stay opted in "until the advance is recouped or for a period of 24 months, whichever comes first." LANDR also says: "Only distributed tracks with full recording and publishing rights are eligible."
LANDR describes two deal shapes: time-limited deals that "pay recurring royalties for as long as the deal runs," and perpetual deals that "pay once" for a dataset that is "never refreshed."
A research paper from Open Data Labs, "The Economics of AI Training Data: A Research Agenda" (October 2025), lists independent music at €0.30 to €2.00 per track as an example of per-unit licensing in 2024. Its table cites a trade publication without a link, and we could not trace the original. Treat it as a secondary estimate, not a market price.
Collecting societies license a share of income; a record company says its terms vary
| Publisher | What it publishes | What it means for an owner |
|---|---|---|
| GEMA | "a 30% share of all net income generated by the generative AI model or system of the provider," plus "a minimum royalty in addition to the standard royalty" | Compositions in its repertoire are licensed for a share of income, not per file |
| STIM | A license for musical works that "assumes that you, as the licensee, has separately obtained the necessary rights to the sound recordings (master rights)"; its first version also bundles master rights for a selected catalog | Composition and master rights are usually cleared separately, even when one agreement bundles them |
| STIM | "If the model is to be retrained in a new version or requires further training, a new license must be obtained." | A license can be tied to one model version |
| Warner Music Group | "all of our deals are based on variable economics" | A record company describes its AI deal terms without figures |
Source: GEMA's licensing model page (October 17, 2024), STIM's AI license page and FAQ, and Warner Music Group's letter to shareholders filed with the SEC; checked October 27, 2026.
STIM's FAQ adds that since its first license was signed in September 2025, "there are currently no concrete examples of how large an individual payout from an AI service may be."
The message for owners is consistent: licensing money follows rights that can be verified. Who wrote the work, who owns the recording and what each contributor agreed to all need records. A catalog where one owner holds both the composition and the master is simpler to clear than one where they are split.
What to prepare before a price conversation
A reviewer cannot price a catalog from a headline count. A short scope sheet lets them trace each part of the offer to files, rights and records.
| Field | What to make explicit | Why it matters |
|---|---|---|
| File counts by category | Counts per UCS category for sound effects; tracks, stems and MIDI files counted separately for music | Defines what is being priced, as the listings above do |
| Ownership of each part | What you recorded or wrote yourself, what came from contributors, and the written grant that covers each | Licenses separate composition, master and contributor rights |
| Format and specs | Container, bit depth, sample rate and channels; whether files are kept as recorded | The listings above state these |
| Metadata | The fields per file, who wrote them, and the naming scheme | The listings above, priced or not, describe their metadata |
| Consent for vocals, stems and sessions | Performer and singer releases that name AI training | Voices and sessions carry rights beyond the recording |
| AI licenses already granted | Who already holds AI-training rights, under what term, and for which models | Earlier licenses shape what a new buyer can get; retraining may need a new license |

Source, scope and calculations
Public pages were captured on October 27, 2026; listings are undated unless a date is given above. The prices are asking prices, advances or published licensing models. None is a verified paid amount, and none is a Rightmark figure.
Calculations: €60,000 / 53,000 = about €1.13; €20,000 / 53,000 = about €0.38; 12 × €3,000 = €36,000; €60,000 / €20,000 = 3; $149 + $100 = $249; $249 / $149 = about 1.67; $5 / 25% = $20.
Audio lots open for interest
Rightmark's private sale catalog lists these audio lots, each described in its card's own words:
- Lot AV-SFX: About 3 million human-recorded sound effects in 83 UCS categories, with metadata written by people.
- Lot AV-TRACKS: About half a million instrumental music tracks with metadata, some with separate stems.
- Lot AV-SONGS: About half a million vocal music tracks with metadata, about 4,000 with separate instrument stems and vocal tracks.
- Lot AV-SESSIONS: 200 vocal songs in full session detail: dry and processed vocals, DI and amped guitars, MIDI, lyrics, chords and effect chains.
- Lot AV-RENDERS: Audio and MIDI pairs rendered to order from deep-sampled virtual instruments, in any key, tempo, layer or stem.
- Lot AV-MUSIC: A European sample-pack label's library: tens of thousands of original loops, one-shots, vocals and sound effects, with thousands of construction kits.
- Lot AV-OPTIN: About 20,000 production-music songs whose composers opted in to AI training in writing, composition and master cleared in one step.
The public prices in this note describe other catalogs. They are not prices for these lots.
