SoundSmith: creator-controlled audio mastering
SoundSmith is Hearthlight's flagship product: an AI-assisted audio mastering tool, not an AI music generator.
It is built for musicians, spoken-word creators, YouTube creators and small studios that want privacy, understandable controls and the ability to review and shape their own mastering decisions.
- Creator-controlled decisions
- AI-assisted, not generative
- Built around privacy and clarity
The SoundSmith application opens separately at soundsmith.hearthlight.uk.

Technology should support the creator, not consume them
Hearthlight makes focused tools that help independent creators finish work without taking ownership or judgement away from them.
Creator ownership
Your work and your creative decisions stay yours.
Privacy by design
Privacy is treated as a practical design requirement from the beginning.
Clear tools over black boxes
Creators should be able to understand the controls they use and the choices those controls affect.
Responsible assistance
Automation supports creative judgement rather than replacing the person making the decision.
Accessibility-led development
Built from real creative constraints
Independent production happens within real limits on time, attention and stamina. Capacity can fluctuate, while the work still needs to remain understandable and possible to finish.
Hearthlight's workflows reduce repetitive steps, make controls easier to follow and support sustainable progress without taking creative decisions away from the person doing the work.
Reduced repetitive workKeep limited energy for decisions that need it.
Clear and readable controlsUnderstand what a tool is doing and which choice comes next.
Keyboard-friendly workflowsKeep essential actions reachable without relying on a pointer.
Sustainable production sessionsSupport useful progress within real independent production capacity.

Most AI mastering tools upload your track, then hand back a result with no explanation of what changed or why. That opacity isn't a technical necessity - it's a choice, and usually not yours. Here's what "black box" mastering actually hides, and why transparency was never really on the menu until no
