Easy Stems

Any song. Every instrument. Your computer.

Drop a track and Easy Stems hands you the drums, bass, guitar, keys, lead vocals, backing vocals and everything else as separate tracks. Nothing is uploaded. Nothing to learn.

Every Song Is a Band

Stems are the raw material of music work, and almost nobody has them. Labels rarely release them, and when they do it's years late and for a handful of hits. So everyone who wants the vocal, the drums or the bass out of a finished record has had three bad options: upload it to a stem website, buy a repair suite that costs hundreds, or learn to drive a command-line tool.

Easy Stems puts the best open models behind one button on your desktop. The audio stays on your machine, and it goes further than the usual four stems: six instruments, with the lead vocal lifted off the backing vocals.

6instruments, not four. Guitar and keys come out on their own.

2vocals, apart. Keep the harmonies, lose the singer.

0bytes uploaded. Unreleased material never leaves the room.

The Split

One File In. Seven Tracks Out.

Keep scrolling and pull the mix apart, the way Easy Stems does.

Try It

Hear It as You Build It

Every stem plays live. Switch one off, solo another or ride a level while the song runs, with no waiting and no re-render. These are the real screens.

The same song with the lead vocal switched off, drums up 3 dB and aux down 6 dB

The same song with only the bass playing

Seven stems, each with its own switch, level, solo and headphone button.

Features

Drop a Song, Get the Band

Everything here is in the app today.

The Easy Stems home screen with a drop zone, the Quick and Full cards, and the library of songs already split

Quick or Full

Quick When You're in a Hurry

Quick runs a lighter model that knows vocals and everything else, several times faster. Pick it for an acapella or a backing track.

Full runs the six-instrument model when you want the whole band. Either way, the song starts playing the moment you drop it and carries on from the same spot when the stems arrive.

A stem's menu open: save this stem, export only lead vocals, export everything but lead vocals, reset level

Just One Part, or All but One

The Part You Came For

Solo a stem and export it alone. Switch one off and export everything else as one file. An instrumental with no lead vocal, a drumless practice mix or a bass-only track is two clicks.

The export panel: selected stems or one mix, WAV, sample rate, bit depth and output folder

Studio-Grade Files

Selected stems as separate files, or everything you can hear as one mix. WAV at 44.1 or 48 kHz, 16 or 24 bit, named and foldered, ready to drag into any DAW.

Batch processing: a queue of songs, one done, one separating, two waiting

A Folder at a Time

Queue a whole set in Batch, walk away, and come back to stems for every song.

Settings: output folder, sample rate, bit depth, separation mode, lead and backing split, graphics card, models and storage

Separate Once

Every song you split stays in your library and reopens instantly. On Windows, a graphics card makes it faster, and it falls back to the processor on its own.

How It Compares

Local, Six Stems, and the Vocals Apart

Repair suites are repair tools with a separator in them. Stem websites are a separator with your audio on their servers. Easy Stems is a separator built for musicians, on your own machine, with the whole band in it.

	Easy Stems	Stem websites	Repair suites
Where your audio goes	Stays on your computer	Uploaded to their servers	Stays on your computer
Stems	Six: drums, bass, guitar, keys, vocals, aux	Usually four	Usually four
Lead and backing vocals apart	Yes	Rarely	No
Live mixer while it plays	Mute, solo and level on every stem	Preview only	Inside the suite
Quick vocals-and-instrumental mode	Yes	Yes	No
Batch	Yes	On paid tiers	Through the host app
Price	One payment, announced at launch	Monthly, or per minute of audio	Part of a suite, hundreds of dollars

How It Works

Three Steps

Drop a song

MP3, WAV, M4A, FLAC, OGG, AAC, or the sound from an MP4 or MOV video. It starts playing straight away.

Pick Quick or Full

Vocals and the rest in a hurry, or the whole band taken apart.

Mute, solo, level, export

Build the mix you need while it plays, then save the stems or one file.

Questions

Does my audio go anywhere?

No. Separation runs on your computer. The only network use is downloading the models once.

How long does a song take?

Full mode is a few minutes per song on a processor, and less with a graphics card. Quick mode is several times faster. A song you've split before opens instantly.

How clean is the split?

It's a best guess from a neural network, not the original multitrack. Dense layered vocals, distorted guitars and thick synths can bleed between stems, and pads and organs often land in Aux rather than Keys.

Can I get just one part?

Yes. Solo a stem and export it alone, or switch one off and export everything else as one file.

I have an Intel Mac. Where is my version?

Easy Stems has two Mac builds, one for Apple silicon and one for Intel. Amanorsac Hub installs the Apple silicon one on every Mac for now, so on an Intel Mac get yours from the website instead:

Once you own Easy Stems, open My Apps and sign in with the same account.
Find Easy Stems and click Mac (Intel), under the Install in Amanorsac Hub button.
Open the .dmg that downloads and drag Easy Stems into Applications.

Not sure which Mac you have? Open the Apple menu and choose About This Mac. If it says Chip: Apple M1 (or M2, M3, M4), you have Apple silicon and the Hub's install is the right one. If it says Processor: Intel, use the Intel build.

Is it a subscription?

No. It will be one payment, for Windows and Mac, installed and updated through Amanorsac Hub. The price comes with the launch.
