Motor Sound Editor (MSE)

Motor Sound Editor is a desktop editor for creating BVE-style train motor sound projects. It replaces manual CSV editing with visual curve editing, real-time layered preview, portable .msep project files, and one-click export for simulator-ready packages.

Core Features

• Visual curve editing: Edit speed-based pitch and volume curves for traction and braking.
• Multi-track preview: Preview layered motor sounds while changing speed and simulator state.
• Portable project files: Package curve data and audio assets in the .msep format.
• BVE export: Generate vehicle.txt, motornoise.txt, CSV tables, and WAV audio.
• MTR export: Generate MTR-compatible sound files, sound.cfg, CSV tables, and sounds.json.
• Windows integration: Supports single-instance behavior and .msep file association.

Development

Prerequisites

• Node.js
• pnpm
• Rust toolchain
• Tauri build dependencies for Windows

Commands

pnpm install
pnpm tauri dev
pnpm build
pnpm tauri build

Project Format

.msep files are zip-based project archives. They contain project metadata, track and curve data, and packaged audio assets, so projects can be moved between machines without losing referenced audio.
