Le Resampler

Le Resampler is a desktop audio sample manager built for music producers who use physical samplers (Akai MPC and compatible devices). Scan your library, organise files by category and tags, preview them, then export them to an SD card in one click — automatically recreating the folder structure expected by your sampler (/kick/, /snare/, /loop/…).

Built with Tauri (Rust + Vanilla JS): lightweight, native, available on macOS, Windows and Linux.

Features

Library scanning — Add a folder and Le Resampler recursively indexes all audio files (WAV, MP3, FLAC, OGG, AIFF…)
Auto-refresh — Re-scan known folders in one click to pick up newly added files
Metadata display — BPM, key, duration, category and type — auto-inferred from filename and audio metadata
Inline editing — Edit category, BPM, key and tags directly in the table
Tag system — Add/remove custom tags per sample; filter the list by tag
Audio preview — Click ▶ on any row to preview; Space bar to stop. Auto-play mode available
Volume control — Slider in the player bar
Multi-select export — Check samples individually or use "Select All", then click Export to copy them to a destination folder. Files are automatically sorted into subfolders by category (/kick/, /snare/, /loop/…)
MPC Sampler compatible — Export directly to an SD card formatted for the Akai MPC. The folder structure created by Le Resampler matches the MPC's expected layout, so your samples are immediately browsable on the device
100% test coverage — Rust backend fully tested with cargo-tarpaulin
CI/CD — GitHub Actions pipeline (fmt, clippy, tests, coverage, weekly releases)
