Spatial Audio & Immersive Music for Drill: UK, Chicago, Brooklyn & Jersey Drill
Spatial9 Team · · Updated · 14 min read
Part of the series Spatial audio and immersive music by genre.
Key takeaways
- Immersive drill keeps the sliding 808 and lead vocal locked in the centre, with the 808 mono so slides stay clear on phones and cars.
- The snare sits front right, hi-hats are raised on the right and dark piano plays from the front left.
- Ad-libs hit from behind left for surprise, while choir and strings rise behind right for dark, cinematic depth.
- Drill vocals should stay dry and direct, and a tight space suits the genre better than big rooms.
Drill grew from Chicago and London into a global sound, with scenes in New York, Brooklyn, Paris and beyond. It is defined by sliding 808 basslines, skippy hi-hats, dark melodies and a cold, menacing mood. In spatial audio, drill does not need to be huge or airy. It needs to feel close, dark and heavy. This guide covers how spatial audio for drill works, where to place each element and how to make an immersive drill mix. For the basics, see what spatial audio is.
Why drill needs a tight, dark 3D mix
Drill's power comes from the 808 and the voice. Spreading them out would weaken the track. Instead, a good immersive drill mix keeps the core centred and uses the space around it for dark textures and ad-libs that surprise the listener.
The rule: 808 and vocal never leave the centre. The space around them stays dark and tight.
Immersive music for drill: what listeners hear
- 808s that slide through you. The bass stays centred and physical.
- A voice up close. The rapper sits right in front, dry and direct.
- Hats with height. Skippy hi-hats rise slightly above.
- Darkness around the edges. Piano, choir and ad-libs create a menacing atmosphere.
Where to place each element in a drill mix
| Element | Position | Height | Why it works |
|---|---|---|---|
| Lead vocal | Front centre | Ear level | Direct and dominant |
| Sliding 808 | Centre | Ear level | The signature low end |
| Snare | Front right | Ear level | Sharp, off-kilter hits |
| Hi-hats | Right | Raised | Skippy energy above |
| Dark piano | Front left | Ear level | Menacing melody |
| Ad-libs | Behind left, moving | Ear level | Surprise hits |
| Choir and strings | Behind right | Raised | Dark, cinematic depth |
The psychoacoustics behind drill placement
Every position in the table above follows how the ear and brain locate sound. Here is the reason behind the main choices for drill.
- Lead vocal in front. The ear's directional resolution is finest in front of the face and much coarser to the sides and behind, so the part you must follow belongs in front. Drill verses are dense, so the voice needs the sharpest position.
- Sliding 808 centred. Deep bass is the hardest sound for the ear to locate. Its wavelengths are several metres long, far larger than your head, so both ears receive almost the same level and only a tiny timing difference. The 808 already moves in pitch, and moving it in space as well would only muddy the low end.
- Hi-hats raised on the right. Height is heard mainly through treble: the folds of the outer ear colour frequencies above roughly 4 kHz differently for each elevation, so airy, bright parts are the ones that truly sound overhead. Fast, bright hats are among the easiest sounds to hear above you.
- Ad-libs moving behind left. The ear needs a larger angle to notice movement than to notice position, so slow, wide moves are followed easily while fast ones blur into a wash. Short moves behind the listener make ad-libs pop without stepping on the verse.
The immersion profile for drill
Low-end focus is at maximum because the sliding 808 defines drill. The space is deliberately tight and dry to keep the cold, close feel.
Tips for an immersive drill mix
- Keep the 808 centred and mono. Its slides must stay clear on phones and cars.
- Keep the vocal dry. Drill vocals are direct, not washed in reverb.
- Throw the ad-libs. Short hits from behind add energy and surprise.
- Use dark textures for width. Piano and choir fill the sides without crowding the centre.
- Avoid big rooms. A tight space suits drill's cold mood.
Drill styles: UK, Chicago, Brooklyn and Jersey drill
The core placement from this guide still applies to every style: the 808 and lead vocal stay locked in the centre, and the space stays tight and dry. Here is what changes from one style to the next.
UK drill
UK drill is defined by sliding 808 basslines, skippy triplet hi-hats, snares landing in off-kilter places and dark piano or string melodies. It sits closest to the main guide. Keep the slides centred and mono, put the snare at front right and lift the skippy hats on the right. Dark piano plays from front left, and choir or strings rise behind right for a cold, cinematic edge.
Chicago drill
Chicago drill is the original sound: slower, bleak and closer to trap, with booming 808s, simple dark melodies and chanted or heavily processed hooks. The 808 hits rather than slides, but it stays just as centred. Bring the melody closer to the front and keep it sparse. Chanted hooks and ad-libs suit behind left, and the choir can sit a little lower than in UK drill.
Brooklyn drill
Brooklyn drill takes UK drill production, with sliding 808s and skippy hats, and pairs it with loud, energetic New York delivery and constant shouted ad-libs. Keep the lead vocal dry and close, because the delivery is aggressive. The ad-libs are the main change: throw them between behind left and the sides more often, as short, punchy hits. Choir and strings stay raised behind right.
Jersey drill
Jersey drill mixes drill vocals and 808s with the bouncy kick patterns and chopped vocal samples of Jersey club. The kick pattern changes, not its position: kick and 808 stay centred. The chopped samples take over from the dark piano, so place them front left and behind, with short hits that answer each other. Keep hats raised on the right and the space tight.
Dolby Atmos and object-based mixing for drill
Dolby Atmos mixes drill as a channel bed plus objects placed anywhere in the room. Most listeners will hear the spatial mix on headphones using binaural rendering through Apple Music, Tidal or Amazon Music. Because each service handles spatial audio differently, checking your mix across formats is essential. Spatial9 helps you plan placements for every format so your drill track translates perfectly. By separating the heavy 808s into the bed and placing crisp vocals and dark textures as objects, you maintain the cold, tight energy drill requires.
How the Atmos plan differs from the placement map. The Atmos plan differs from the Ambisonics map by using room depth rather than just direction. The sliding 808 is routed to the centre bed and LFE rather than placed behind and to the right, ensuring the low end stays solid. The lead vocal is pulled slightly off the front wall to add depth. The choir and strings remain raised and behind on the right, but use a large object size to wash the rear corner without losing focus.
Beds and objects for each drill element
| Element | Atmos role | Where it plays in 7.1.4 | Binaural mode | Why |
|---|---|---|---|---|
| Lead vocal | Object, small size | Ear level, front of the room, centre (X 0, Y 0.7, Z 0) | Near | keeps the vocal direct and dominant in the centre |
| Sliding 808 | Bed | Centre plus LFE (C + LFE) | Off | anchors the signature low end solidly in the centre |
| Snare | Object | Ear level, front of the room, right (X 0.4, Y 0.6, Z 0) | Mid | provides sharp off-kilter hits slightly off centre |
| Hi-hats | Object | Raised, front of the room, right (X 0.6, Y 0.5, Z 0.5) | Mid | adds skippy energy above the main stage |
| Dark piano | Object, medium size | Ear level, front of the room, left (X -0.6, Y 0.6, Z 0) | Mid | creates a menacing melody on the left side |
| Ad-libs | Object, small size, moving | Ear level, rear of the room, far left (X -0.8, Y -0.5, Z 0). Moving: Sweeps behind the listener to add surprise, ending at raised, back wall, left | Mid | delivers unexpected hits from the rear left |
| Choir / strings | Object, wide size | Overhead, rear of the room, far right (X 0.8, Y -0.6, Z 0.7) | Far | adds dark cinematic depth behind and above |
Dolby Atmos settings for drill
- LFE. The LFE channel exists only in the bed, so route the sliding 808 there and keep objects free of low-frequency foundations to rely on bass management.
- Object size. Use point or small sizes for the lead vocal and snare to keep them focused, while using medium or large for the dark piano and choir to spread them across speakers.
- Height use. Keep the core beat at ear level, reserving height for hi-hats and choir to prevent the mix from losing focus on headphones and fold-downs.
- Binaural render. Set the sliding 808 to off for a solid centre, the lead vocal to near for intimacy, and the choir to far for distant depth.
- Tight space. Avoid excessive reverb on the vocal and snare objects to maintain the cold, dry and menacing mood essential to drill music.
Drill across immersive formats
| Format | How it carries sound | What it means for drill |
|---|---|---|
| Dolby Atmos | Hybrid: a 7.1.2 channel bed plus up to 118 objects placed with X, Y and Z metadata | Dolby Atmos is a hybrid format allowing up to 118 objects alongside a channel bed for precise drill placements. |
| Sony 360 Reality Audio | Object-based, built on MPEG-H 3D Audio: every sound is an object on a sphere | Sony 360 Reality Audio has no channel bed, placing every drill element as an object on a sphere around the listener. |
| MPEG-H 3D Audio | Channels, objects and Higher Order Ambisonics in one stream, with optional listener control | MPEG-H 3D Audio carries channels, objects and Ambisonics, letting listeners adjust the level of drill objects if allowed. |
| Auro-3D | Channel-based: a height layer above 5.1 or 7.1, with an optional overhead channel | Auro-3D relies on fixed channels rather than objects to provide a height layer above your drill mix. |
| Eclipsa Audio (IAMF) | Channel-based and scene-based (Ambisonics) audio elements; no objects | Eclipsa Audio uses IAMF which has no audio objects, so your Atmos drill mix is rendered to channels or Ambisonics. |
| Ambisonics | Scene-based: the whole sound field, decoded to any speaker layout or to headphones | Ambisonics stores the entire drill sound field as spherical harmonic components that decode to any speaker layout or headphones. |
| ADM BWF | Open exchange file (ITU-R BS.2076 metadata in a BW64 file) for channels, objects and scenes | ADM BWF is the open metadata format used to deliver your final drill master to streaming services. |
Delivery checklist for a drill Dolby Atmos release
- Master file. ADM BWF at 48 kHz and 24-bit, with no more than 128 channels: a 10-channel 7.1.2 bed plus up to 118 objects.
- Loudness. Integrated loudness no higher than -18 LKFS and true peak no higher than -1 dBTP, measured to ITU-R BS.1770.
- Binaural metadata. Set Off, Near, Mid or Far for every bed and object. Masters with everything left on Off are rejected.
- Re-renders. Listen to the 5.1, stereo and binaural re-renders before delivery, because most people will hear one of them.
Check that the integrated loudness of your final ADM BWF master is no higher than -18 LKFS before delivery.

Frequently asked questions
Does this guide cover UK, Chicago, Brooklyn and Jersey drill?
Yes. All four keep the 808 and lead vocal centred in a tight, dry space. UK drill follows the main layout with skippy hats raised on the right and dark piano front left. Chicago drill keeps melodies sparse and closer to the front. Brooklyn drill throws more shouted ad-libs from behind and the sides. Jersey drill swaps the piano for chopped club samples placed front left and behind.
Can I make a drill mix in Dolby Atmos or Eclipsa Audio?
Can I make a drill mix in Dolby Atmos? Yes, Dolby Atmos is ideal for drill because it allows you to anchor the heavy 808 in the channel bed while placing crisp hi-hats and dark melodies as objects. Remember that Apple Music applies its own spatial renderer, so its headphone result can differ from the Dolby binaural render and must be checked separately. Also note that Eclipsa Audio is a separate delivery since it uses IAMF and has no audio objects.
Should drill elements be beds or objects in Dolby Atmos?
Should drill elements be beds or objects in Dolby Atmos? The sliding 808 should always be in the bed, routed to the centre and LFE to keep the low end solid and mono. The lead vocal, snare, hi-hats, dark piano and ad-libs work best as objects. This allows you to pull the vocal slightly off the front wall for depth, precisely place the skippy hi-hats above, and automate the ad-libs to sweep behind the listener for added surprise.
Does a drill Dolby Atmos mix also work for Sony 360 Reality Audio and MPEG-H?
Does a drill Dolby Atmos mix also work for Sony 360 Reality Audio and MPEG-H? They are different formats, so a direct transfer requires adjustments. Sony 360 Reality Audio is built on MPEG-H 3D Audio but has no channel bed, meaning your sliding 808 must be converted into an object on a sphere. MPEG-H 3D Audio supports channels, objects and Ambisonics, and is used in broadcasting, allowing listeners to adjust the levels of specific objects if the producer allows it.
Is spatial audio good for drill?
Yes, when the 808 and vocal stay centred. Dark textures and ad-libs around the listener make the track feel more menacing.
Should the 808 be spread in 3D?
No. Keep it centred and mono so its slides stay powerful on every system.
How is drill different from trap in spatial audio?
Drill uses a tighter, darker space and more off-kilter rhythms. Trap can be wider and more spacious.
Can I convert a finished drill track to spatial audio?
Yes. Spatial9 uses AI to generate an immersive mix from a stereo master and exports it as Eclipsa Audio, ADM, binaural or Ambisonics.
Does immersive drill work on normal headphones?
Yes. The mix is rendered binaurally, so the 3D effect works on any regular headphones.
