Lofi Engine

seed —
ready

No AI. No model, no training data, no third-party samples.

Before you generate anything

Any generator can sound good once. These are ten seeds across eight moods, so you can judge the tenth loop instead of the first.

Pre-rendered files, not live renders. Each clip is a four-bar seamless loop rendered headlessly by the engine on this page, encoded to Ogg Vorbis, and fetched only when you press it — about 120 KB each. Each one repeats until you stop it, so the seam is there to be caught. These clips are the only thing this page ever downloads: pressing Generate still makes no network request at all, which you can watch in the network tab.

Why this is different

A licensing claim needs somebody to make it. This engine is built so that nobody is there.

Generated, not retrieved

Every track is composed on the spot by this engine and synthesised from oscillators, filters and envelopes — the way a drum machine makes a kick drum. Nothing is looked up, matched, or reassembled out of anybody’s recording.

Deterministic from a seed

A track is a seed plus a handful of numbers — about 200 bytes. The same seed renders the same audio every time, on any machine. Commit the seed beside your project and your build reproduces the music without a round trip to anyone’s server.

No model, no corpus, no claimant

There is no neural network, no training data and no third-party sample library in the chain. No label, no composer, no rights society and no model owner has ever touched this audio, so there is no second party to it at all.

Nothing registered to match against

Content ID and the systems like it work by matching audio against a database of registered recordings. A track rendered from your seed has never been registered, because until you pressed Generate it did not exist. That is a statement about how matching works, not a promise about how a platform will behave.

	AI music generators	Royalty-free libraries	Lofi Engine
Where the audio comes from	A model trained on recordings other people made.	Tracks written and performed by musicians the library licenses from.	An algorithm synthesising every note on your machine.
Who else has a stake	The model’s owner — and, still unsettled in court, whoever’s recordings trained it.	The composer, the library, and any rights society they belong to.	Nobody. There is no other party to have one.
If the terms change	Your licence lives with a company whose terms and catalogue can move.	Tracks get pulled, re-licensed, or moved behind a higher tier.	Nothing to change. The WAV is already on your disk.
Exclusivity	Often non-exclusive; other users can prompt something near-identical.	The same popular track ships in a thousand other games.	Your seed renders audio that exists nowhere else.
Musical range	Wide. Any genre you can describe.	Wide. Real instruments, real players.	Lofi. One genre, on purpose.
Cost	Usually a subscription.	Usually a subscription.	Free. No account, no key.

Two things this is honestly worse at. An AI generator will cover far more ground than one genre, and a stocked library will hand you a real drummer in a real room. Lofi Engine does lofi, from an algorithm, and that narrowness is exactly what keeps the rights story short enough to fit on this page. Everything above is checkable rather than promised: the engine is deterministic, the source of every sound is an oscillator, and there is no model or corpus to go looking for.

The pack

If you would rather not generate them yourself: 28 finished tracks out of this same engine, named and packaged, under exactly the licence below.

28 tracks across all eight moods on this page. Named, not numbered.
Each one twice. A 16-bar seamless loop (42–59 s) to sit under gameplay, and a full version with an intro, development and an ending (2:47–2:50) for menus, trailers and credits. 1 h 43 m of music in 112 files.
WAV and OGG for every file. 44.1 kHz 16-bit stereo PCM, peak −0.355 dBFS, every track at −14 LUFS — so Unity’s −0.3 dBFS rule passes and a crossfade between any two does not dip or bulge.
Unity .meta files beside every WAV. Loops import as PCM / Decompress on Load, so nothing is re-encoded across the loop point; full versions stream. Drop the folder into Assets/ and there is nothing to configure.
Every track’s seed ships with it. The engine is deterministic, so any track in the pack can be regenerated from its seed and shown to have come from this engine rather than from a catalogue. Provenance you can reproduce, not a claim you have to take.
One payment. No subscription to lapse while your game is still on sale, no key, no attribution, no royalties — the licence below covers the pack word for word.

The generator on this page stays free, with no account and no cap. The pack is not a better engine — it is the same one, with the picking, naming, rendering and packaging already done, and a full-length version of every loop. If you would rather spend the afternoon pressing Generate, do that instead; nothing in the pack is out of reach from here.

Licence

Anything this page generates for you is yours. That is the whole deal — spelled out below so you can paste it into a publisher’s form.

What you can do

Ship it in commercial games.: Paid, free-to-play, ad-supported, early access, console ports, publisher-funded. No revenue cap, no reporting, no threshold at which you owe something.
Ship it in non-commercial games.: Jam entries, student work, mods, prototypes, and things you never release.
Use it in unlimited projects.: One track or five hundred, across every title you ever make. There is no per-project, per-seat or per-studio count.
Skip attribution.: A credit is welcome. It is never required, and nothing changes if you leave it out.
Pay no royalties.: No revenue share, no per-unit fee, no back end, and no subscription that can lapse while your game is still on sale.
Keep it worldwide and perpetual.: Every territory, forever, irrevocably. The WAV is on your disk; there is no server that could take it back.
Edit it.: Cut it, re-pitch it, layer it, run it through your own effects, drive it from FMOD, Wwise or an Unreal MetaSound. It is raw material, not a finished product you must preserve.
Use it outside games too.: Trailers, devlogs, storefront and capsule videos, streams, podcasts, apps and client work.

The one thing you cannot do

Do not resell the audio as music.: You may not redistribute generated tracks — alone or bundled — as a stock-music, sample or loop-pack product, or upload them to a music distributor. Music inside your game is your game. Music sold as music is the one use that competes with this engine.
Do not register it in a rights database.: Keep it out of Content ID and out of any performing-rights registration. Claiming generated audio as a registered recording would point a matching system at output that other people are entitled to generate.

Fine print, such as it is

Offered as-is.: No warranty of any kind. Listen to what you exported before you ship it — nobody here has heard it either.
The audio only.: This licence covers the tracks you generate. It does not grant rights in the Lofi Engine name or in the engine’s source.
Nothing upstream to depend on.: Because no AI model, no training data and no third-party samples are involved, this grant does not rest on anyone else’s permission. There is no chain of title to break.

No sign-up, no licence key, no account. Downloading the WAV is the entire transaction. If a storefront or a publisher asks you to evidence the rights, link them to this page.
