Le Resampler is a desktop app for music producers who use hardware samplers like the Akai MPC. It helps you manage a library of audio samples on your computer and then get them onto an SD card in the exact folder layout your MPC expects, so the sounds are ready to browse on the device. You point the app at a folder and it scans it for audio files such as WAV, MP3, FLAC, OGG, and AIFF, reading things like BPM, musical key, duration, and category from the filenames and audio metadata. You can edit that information directly in a table, add your own tags to samples, and filter the list by tag. Each sample can be previewed by clicking play or pressing the space bar, with a volume slider in the player. When you are ready to export, you select individual samples or all of them and click Export. The app copies the files to a destination folder and automatically sorts them into subfolders by category, such as kick, snare, or loop, matching the structure an Akai MPC sampler expects. The app is built with Tauri, a framework that combines a Rust backend with a plain JavaScript frontend, which keeps it lightweight and lets it run natively on macOS, Windows, and Linux. The Rust backend handles scanning, a local SQLite database, audio preview, and the export logic, and the README notes it has full test coverage along with an automated build and release pipeline. To use it, you install a prebuilt version from Homebrew on macOS or download an installer for Windows or Linux. Developers who want to build it themselves need Rust and the Tauri command line tool installed. The project is released under the MIT license.
