Beat stems: what they are and how to use them (2026)

Beat stems are the separate audio files that make up a beat: the drums, the 808, the melody and the effects, each saved as its own WAV. A normal beat file has every sound locked together. Stems split them apart, so a mix engineer can turn each part up or down around your voice. That is the difference between a song that sounds “okay” and one that sounds finished.

In short

• Stems are the beat in parts, each sound or group as its own WAV file.
• They matter for mixing, because your engineer can make room for your vocal.
• On Airtune, stems come with Easy Stems (from ₹1,999) or an Exclusive licence.

What are beat stems?

Beat stems are the individual parts of a beat, exported as separate audio files that all start at the same point. Play them together and you hear the full beat. Mute one and that sound disappears. In audio production, a stem is a group of sounds mixed together so it can be handled as one unit later.

In beat sales, people use “stems” and “track-outs” loosely. A stems folder might hold one file per instrument, such as kick, snare, hi-hats, 808 and melody. Or it might group sounds, such as all drums in one file. Both are common, so check the beat page if you need a certain level of detail.

Stems are usually WAV files, all the same length, so they line up when you drop them into a session. A good set is clearly named and includes the BPM and key. That makes life easy for whoever mixes your song.

A typical stems folder might look like this:

• Kick and snare: the main drum hits, sometimes in separate files.
• Hi-hats and percussion: the fast, small rhythm parts.
• 808 or bass: the low end, often the most important file to mix.
• Melody: piano, guitar, synth or sample loops.
• FX: risers, reverses and transitions.

Why do beat stems matter for mixing?

Beat stems matter for mixing because they let an engineer shape each sound around your vocal. With a single WAV, the engineer can only treat the whole beat at once. If the melody clashes with your voice, they can turn down the entire beat, but not just the melody.

With stems, the engineer can lower one sound under the hook, cut space in the 808 for your lowest notes, or soften loud hi-hats. They can also mute parts to make an intro, a drop or a breakdown. Small changes like these make a song sound clear on phone speakers, earphones and car systems.

Stems also help beyond mixing. You can make a clean instrumental or a performance version for shows. You can shorten the beat for a reel. Our guide to MP3 lease vs WAV lease explains when a WAV is enough and when stems are worth the extra cost.

• Make room for vocals: turn down only the parts that clash with your voice.
• Control the low end: balance the 808 and kick so the song does not sound muddy.
• Rearrange: mute parts to build intros, drops and breakdowns.
• Make versions: clean instrumentals, show versions and short edits.

How do you get stems with an Airtune licence?

On Airtune, you get beat stems with an Easy Stems licence or an Exclusive. Easy Stems gives you the MP3, the WAV and the track stems. Its minimum price is ₹1,999, or $49.99 for buyers abroad, and producers can price above that. The Exclusive adds the project file and takes the beat off sale.

Airtune’s rights table lists “separate stems to mix every track” only for Easy Stems and Exclusive. Easy MP3 and Easy WAV do not include stems. Every Easy licence still allows unlimited audio streams and unlimited monetised music videos, so stems are about mixing control, not more rights.

Easy Stems is negotiable by default, so you can make an offer from the beat page. Your files are delivered up to the level you bought, through short-lived download links. Airtune does not promise to store files forever, so download and back up your stems straight away. See the full table on Airtune licensing.

Worked example. Say a producer prices Easy WAV at ₹999 and Easy Stems at ₹1,999, the two minimums. Stems cost you ₹1,000 more. If you make an offer on the stems, the agreed price can never go below ₹999.50, which is half of the ₹1,999 minimum.

Tip: if you already know a mix engineer will work on the song, buy stems from the start. It is simpler than going back for them later.

How do you send beat stems to a mix engineer?

You send beat stems to a mix engineer as one tidy, zipped folder with clear names and a short note. The engineer should be able to open the session and start work without asking you anything. That saves time, and with paid mixing, time is money.

Before you send, check that every stem starts at the same point and plays in sync with the full beat. Add your vocal files too, exported dry, without reverb or effects, unless you want them kept. Include the full beat as a reference so the engineer can hear the producer’s balance.

Share the folder through a cloud link, because stems are often too big for chat apps. Add the BPM, the key, and any notes such as “808 too loud in the hook”. If you need someone to mix it, you can hire a mixing engineer on Airtune Artist Services. Our guide to mixing and mastering in India explains what to expect.

1. Download the stems and the full beat WAV from your licence.
2. Check sync: drop all stems into a session and play them with the full beat.
3. Name files clearly, for example “Kick”, “808”, “Melody”, with BPM and key.
4. Add your vocals, dry, as separate WAV files from the same start point.
5. Write a short note with your goals and any problems you hear.
6. Zip and share one folder by cloud link, and keep your own backup.

Can an AI stem splitter replace real beat stems?

An AI stem splitter can pull rough parts out of a finished beat, but it does not replace real beat stems. Splitters guess which sounds belong to drums, bass or melody. The results often have artefacts, such as a bit of hi-hat left in the melody or a thin, watery 808.

Real stems come straight from the producer’s session, so each one is clean and complete. An engineer can push them hard in a mix without odd sounds appearing. For a release you care about, that quality difference is easy to hear.

There is also the licence to think about. Splitting a beat does not change what your licence allows. On Airtune, the rights table lists separate stems for mixing only on Easy Stems and Exclusive. Read your licence terms before you use split parts in a release. Our guide to leasing beats explains what each lease covers.

For producers: how to export beat stems

To export beat stems, route each sound or group to its own mixer track and export every track as a WAV from the very start of the beat to the end. All files should be the same length. Most DAWs, including FL Studio and Ableton Live, can export every track as a separate file in one go. Name each file clearly, add the BPM and key, and listen to the stems together before you upload. On Airtune, you upload your WAV and stems once, and buyers get them with the licence they choose.
