Do my project details leave this browser?

No. The checklist and manifest are generated in the current browser tab. LangBeat portfolio analytics receive only milestone names and the page surface, not project names, filenames, notes, BPM, or export settings.

Why should stems start together and have the same length?

A common start point and equal render length let a collaborator place the files at the same timeline position and preserve their alignment.

Which sample rate and bit depth should I use?

Use the settings requested by the recipient or project. The builder records the agreed settings; it does not prescribe one universal delivery format.

LangBeat creator utility · no upload required

Send stems your collaborator can open and trust.

Run the checks that prevent alignment, naming, routing, and export-setting confusion. Then create a plain-text delivery manifest to send with the files.

Everything you type stays in this browser tab.

Stem handoff checklist

All stems begin at the same timeline position.
All files cover the same render length, including intentional silence and effect tails.
File names identify the musical role without “final-final” ambiguity.
Sample rate, bit depth, and file type match the recipient’s request.
Nothing clips unintentionally, and normalization is off unless specifically requested.
Creative effects are included intentionally; dry alternatives are supplied when agreed.
The folder includes a current reference mix and only the intended files.
Everyone involved has confirmed the intended use and necessary rights.

Delivery note

Build the manifest

This is a coordination tool, not audio quality control. Listen to the exported files, inspect them in the receiving session, and follow the recipient’s specifications before delivery.

The alignment and export reminders are consistent with Ableton’s official stem import/export guidance. DAWs and recipients differ, so the agreed delivery specification controls.

From preparation to exploration

Hear what separated parts make possible.

LangBeat is an experimental music system for six-stem separation and controlled transitions. Use only audio you have the right to process.
