HOW IT WORKS
From rough exports to a handoff-ready session.
01 · Upload your stems
Drag in everything FL Studio, Logic, or Ableton exported — no manual sorting first.
02 · Review in seconds
See the detected instrument, group, BPM, and key for every file — then fix anything before export.
03 · Download one clean ZIP
Get organized folders, safe filenames, and empty files already excluded.
SEE IT IN ACTION
From export chaos to a session you can actually read.

WHAT IT ACTUALLY DOES
Useful automation, with the important details left in your hands.
Instrument-aware grouping
Classifies stem instrument types with deterministic audio analysis — not a generative AI call for every file.
BPM and key, with context
Detection is shown with a confidence score and is always editable — useful, never claimed as perfect.
A predictable delivery structure
Groups files into DRUMS, BASS, MELODY, VOCALS, FX, and a MASTER BUS folder with safe names.
Your audio stays untouched
Files are never re-encoded or altered. Original audio bytes are copied exactly under new names and folders.
BUILT BY A PRODUCER
Made by Dave Nunes for the people delivering real sessions.
Stem Organizer is built around the messy reality of exports, revisions, handoffs, and naming conventions — not a generic file manager.
PRIVACY FIRST
Your audio is never the product.
Private account-scoped storage, no public download URLs, no model training, and automatic deletion within 24 hours.
Private by default
Every file lives inside your own private account scope.
24-hour retention
Source stems and generated ZIPs are automatically deleted after processing.
Original audio intact
Your audio is copied byte-for-byte, never re-encoded or changed.
