Threshold Lab is a desktop audio laboratory for turning an intention into an original guided listening session—without hiding the recipe that made it.

The macOS release is being prepared first for the Mac App Store. Windows is planned to follow through the Microsoft Store.

From intention to audio

A process you can inspect, repeat, and make your own.

Threshold Lab keeps the creative thinking, structured plan, plain-language explanation, and finished audio together. You can listen to the result and still see how it was made.

01

Describe the intention

Begin with a purpose, duration, pacing, sound bed, narration style, and return path.

02

Inspect the plan

Review a timed structure of audio segments, narration cues, transitions, and gentle awareness lanterns.

03

Render and audition

Generate narration and procedural sound locally, then balance voice, tone, noise, nature, and volume.

04

Keep the whole bundle

Export the lossless WAV beside its prompt, portable plan JSON, and descriptive text file.

Three ways into the laboratory

Start where your confidence is.

Explore a finished design, describe what you want, or build every segment yourself. The app does not require meditation expertise or AI expertise to begin.

01

Session Library

Learn by looking and listening.

Explore twenty original built-in designs across eight families. Compare each design prompt, plan, description, and WAV before adapting anything.

  • Original curated starting points
  • Readable source materials
  • Direct handoff into AI Lab
02

AI Lab

Describe the experience in ordinary language.

Ask a supported AI provider for a bounded session plan, inspect every proposed segment, and keep the exact prompt used to create it.

  • Provider connection stays explicit
  • Portable plan import and export
  • Local narration and audio rendering
03

Session Creator

Build directly, without AI.

Set the timeline, layers, narration, mix, and duration yourself. Import an existing voice track or render a selected local voice.

  • Manual timeline control
  • Procedural tone, noise, and nature beds
  • Lossless local export

The learning bundle

The WAV is the result—not the only thing you receive.

Every desktop export is designed to preserve four matching artifacts. Together they make a session understandable, portable, and easier to refine from direct experience.

Recorded prompts stay identified as recorded. Older or manual sessions receive a clearly labeled reconstructed learning prompt rather than invented history.

An original starting library

Eight families for learning what changes the experience.

Built-in designs range from short calibration checks to longer witness and integration sessions. They are starting points for comparison, not a prescribed progression.

A plain data boundary

Local where the sound is made. Explicit where a provider is used.

Procedural audio, narration rendering, playback, session history, Experience Records, and WAV export are handled on your computer.

AI Lab contacts a selected third-party provider only when you ask it to generate a plan. The planning prompt and context are then subject to that provider's account, terms, and privacy practices. Session Creator works without an AI provider.

Optional Experience Records

The app offers a notebook. It does not grade the person.

If reflection is useful, record body rest, awareness continuity, return quality, observations, and what you might change next time.

Every field is optional. Records never unlock sessions, score outcomes, gate app use, or define personal progress. The human user remains the judge of the experience.

Release path

The desktop laboratory will be sold as a one-time purchase.

Threshold Lab is still in active development. Store links, pricing, system requirements, and a release date will appear here only after they are verified.

In the product roadmap

There is no public download, preorder, or store purchase available yet.

Responsible use

A user-directed creative tool with clear limits.

Threshold Lab is not a medical device, therapy product, diagnostic tool, or promise of a particular mental, physical, spiritual, or altered-state outcome.

Use headphones only in a safe setting. Never use sessions while driving or operating machinery. Stop if you experience distress, dizziness, unusual discomfort, or another adverse reaction.

Threshold Lab for Mac

The first public release is taking shape.

Until then, this site will stay honest about what is implemented, what is being tested, and what is not yet available.
