Spatial Audio & Immersive Music for Liquid Drum and Bass: Atmospheric Drum and Bass, Soulful Drum and Bass & Jazzstep
Spatial9 Team · · Updated · 16 min read
Part of the series Spatial audio and immersive music by genre.
Key takeaways
- In a spatial liquid drum and bass mix the kick, snare and warm sub bass stay locked in the centre, while the vocal, Rhodes keys, ghost percussion, strings, hats, pads and vocal echoes spread around the listener.
- Splitting the soulful vocal and the Rhodes chords to different sides keeps lyrics clear, because sounds from different directions mask each other less, an effect known as spatial release from masking.
- Liquid drum and bass gains most from width and space, so strings, pads and reverb should wrap the listener while the fast drums stay fairly dry and centred.
- The liquid drum and bass immersion profile scores width 5, height 4, movement 3, low-end focus 4 and space 5 out of 5.
Liquid drum and bass is the soulful, melodic side of drum and bass. It took shape in the UK in the late 1990s and early 2000s, first under the name liquid funk, building on the atmospheric drum and bass of the mid 1990s. It keeps the drum and bass tempo, usually around 170 to 176 BPM, but swaps aggressive bass design for warm sub bass, jazz and soul chords, Rhodes and piano, strings, pads and sung vocals. The drums still roll fast, yet the mood is relaxed and emotional. Because the track runs at two speeds, quick drums over slow, lush harmony, there is a lot of space to fill around the beat. That space is where spatial audio does its best work. This guide covers how spatial audio for liquid drum and bass works, where to place each element and how to make an immersive liquid drum and bass mix. For the basics, see what spatial audio is.
Why liquid drum and bass is ideal for spatial audio
Liquid drum and bass is full of long, warm sounds: held string chords, soft pads, Rhodes voicings and reverb tails. In stereo they pile up behind the drums and the vocal, and the mix can turn muddy. In an immersive mix the harmony can surround the listener while the drums and sub stay tight in the middle, so the track feels both fast and calm.
The rule: tight drums in the middle, warm harmony all around. The kick, snare and sub stay put, while keys, strings and pads build a room around the listener.
Immersive music for liquid drum and bass: what listeners hear
- Drums that roll without rushing. Kick and snare stay tight and centred.
- A voice close to you. The vocal sits just off centre, warm and clear.
- Harmony that surrounds you. Strings, keys and pads fill the sides and the space above.
- Echoes that drift away. Vocal delays float slowly behind the listener.
Where to place each element in a liquid drum and bass mix
| Element | Position | Height | Why it works |
|---|---|---|---|
| Kick & snare | Front centre | Ear level | The fast, steady roll |
| Sub bass | Centre | Ear level | Warm, round low end |
| Lead vocal | Front left | Ear level | Soulful and close |
| Ghost perc | Front right, moving | Ear level | Light swing between the hits |
| Rhodes keys | Left | Ear level | Jazz and soul chords beside the groove |
| Strings | Right | Raised | Lift and emotion above the drums |
| Rolling hats | Behind right | Raised | Shimmer that keeps the pace |
| Pads | Behind left | Raised | A warm bed around the listener |
| Vocal echo | Behind, moving | Raised | Delays that drift and fade |
The psychoacoustics behind liquid drum and bass placement
Every position in the table above follows how the ear and brain locate sound. Here is the reason behind the main choices for liquid drum and bass.
- Sub bass stays centred. The ear finds almost no direction in frequencies below roughly 80 to 100 Hz, so a liquid sub gains nothing from being spread. Keeping it centred and mono keeps it round and steady on any system, from a club to earbuds.
- Vocal and Rhodes on separate sides. Two sounds that share a frequency range mask each other far less when they arrive from different directions. This is spatial release from masking. Soul vocals and Rhodes chords both sit in the mids, so splitting them keeps every word clear.
- Strings and hats raised. The outer ear shapes the spectrum of a sound differently depending on its height, and the brain reads those spectral cues as elevation (Hebrank and Wright). Bright strings and hats carry the high frequencies these cues rely on, so they lift convincingly above the drums.
- Pads around and behind. Sound arriving from the sides soon after the direct sound is what makes a room feel wide and enveloping. Spreading liquid pads and reverb around the listener creates the warm, open feeling the genre is known for.
The immersion profile for liquid drum and bass
Width and space are at maximum because strings, keys, pads and reverb are central to the sound. Height is high because strings and hats sit naturally above the drums. Movement is only moderate: the drums are fast, but the feel is smooth, so only light percussion and echoes travel. Low-end focus is strong but below heavier drum and bass styles, because the sub is warm and supportive rather than the main event.
Tips for an immersive liquid drum and bass mix
- Keep the sub mono. The warm bass must stay identical from every direction.
- Keep the drums tight. Fast breaks smear in a big room, so keep the main hits fairly dry and centred.
- Give the harmony the space. Let strings, keys and pads wrap the listener rather than the drums.
- Keep the vocal close. A soulful vocal should feel intimate, with its echoes doing the travelling.
- Move slowly. Use gentle, gradual motion so the track stays calm at full tempo.
Liquid Drum and Bass styles: atmospheric drum and bass, soulful drum and bass and jazzstep
The core placement holds for every liquid style: drums and sub in the middle, harmony around the listener. What changes is how much space the track needs and which instruments carry the melody.
Atmospheric Drum and Bass
Atmospheric drum and bass, sometimes called intelligent drum and bass, came first, in the mid 1990s, and it is the most spacious of the three. Long pads, ambient textures and washed-out samples matter more than vocals. Push pads and textures wide and high so they surround the listener, and let field recordings or ambient samples sit far behind. Keep the breaks light and centred, with rides raised. Use long reverb on the atmosphere but keep the drums fairly dry so they do not blur.
Soulful Drum and Bass
Soulful drum and bass is built around a sung vocal, often with gospel or soul phrasing, plus piano, strings and warm chords. The vocal is the focus, so keep it front and close, slightly off centre, with backing vocals spread wider on both sides and slightly raised. Piano and Rhodes can sit left, strings right and high. Let vocal delays drift behind. Keep the sub warm and centred so the emotion of the song stays on top.
Jazzstep
Jazzstep emerged in the late 1990s and blends drum and bass rhythms with jazz harmony and instruments: double bass, horns, vibraphone, piano and live-sounding drums. Place it like a small band around the listener. Horns and vibes can take the front sides, piano a little further left, and the double bass stays centred with the sub. Keep the drum kit fairly natural in front, with cymbals raised. A shorter room reverb suits the live feel better than long pads.
Related styles such as minimal liquid and sambass follow the same idea: tight drums and sub in the middle, with melody and harmony spread around the listener.
Dolby Atmos and object-based mixing for liquid drum and bass
Dolby Atmos mixes liquid drum and bass as a channel bed plus objects placed anywhere in the room. Most listeners will hear the mix on headphones through binaural rendering on Apple Music, Tidal or Amazon Music. Spatial9 helps plan placements for every format so the mix translates perfectly. The channel bed provides a solid foundation for the fast drums and warm sub bass. Objects allow precise placement for the soulful vocals, keys and percussion. This hybrid approach ensures the track feels wide and immersive while retaining its driving rhythm.
How the Atmos plan differs from the placement map. The Atmos plan differs from the Ambisonics map to use room depth and keep the main stage in front. The sub bass was behind in the map, but Atmos practice places low end in the front bed to keep it solid. The rolling hats and vocal echo move forward slightly to avoid cluttering the rear. The pads move to a full bed rather than sitting behind on the left. This ensures the fast drums remain focused while the harmony wraps the listener.
Beds and objects for each liquid drum and bass element
| Element | Atmos role | Where it plays in 7.1.4 | Binaural mode | Why |
|---|---|---|---|---|
| Kick & snare | Bed | Centre plus LFE (C + LFE) | Off | anchors the fast breakbeat firmly in the centre |
| Sub bass | Bed | Centre plus LFE (C + LFE) | Off | keeps the warm low frequencies solid and steady |
| Lead vocal | Object, small size | Ear level, front of the room, centre (X -0.15, Y 0.8, Z 0) | Near | keeps the soulful vocal intimate and close |
| Ghost perc | Object, small size, moving | Ear level, front of the room, right (X 0.3, Y 0.6, Z 0). Moving: Shifts slightly across the front right between hits, ending at ear level, front of the room, right | Mid | adds light swing to the fast drum groove |
| Rhodes keys | Object, medium size | Ear level, front of the room, left (X -0.7, Y 0.3, Z 0) | Mid | pulls the jazz chords wide to leave room |
| Strings | Object, medium size | Raised, front of the room, right (X 0.7, Y 0.3, Z 0.4) | Mid | lifts the emotional harmony above the dense drums |
| Rolling hats | Object, small size | Raised, middle of the room, right (X 0.6, Y -0.2, Z 0.5) | Mid | spreads high frequency energy away from the snare |
| Pads | Bed | Whole 7.1.2 bed | Far | wraps the listener in a warm atmospheric room |
| Vocal echo | Object, small size, moving | Overhead, rear of the room, right (X 0.4, Y -0.6, Z 0.7). Moving: Drifts across the rear ceiling as it fades, ending at overhead, rear of the room, left | Far | creates deep space behind the listener |
Dolby Atmos settings for liquid drum and bass
- LFE. Route the kick and sub bass to the LFE channel in the bed, as objects have no LFE send.
- Object size. Keep the lead vocal and percussion small for focus, but increase size for Rhodes keys and strings to add width.
- Height. Use the ceiling for strings, hats and vocal echoes to create the signature airy space of liquid drum and bass.
- Binaural modes. Set the kick and sub bass to off for a solid centre, use near for the vocal, and far for pads.
- Bass management. Remember that low end placed as an object relies entirely on the playback system bass management.
Liquid drum and bass across immersive formats
| Format | How it carries sound | What it means for liquid drum and bass |
|---|---|---|
| Dolby Atmos | Hybrid: a 7.1.2 channel bed plus up to 118 objects placed with X, Y and Z metadata | Dolby Atmos uses a channel bed for the drum foundation and objects for the soulful vocals and floating melodies. |
| Sony 360 Reality Audio | Object-based, built on MPEG-H 3D Audio: every sound is an object on a sphere | Sony 360 Reality Audio places every liquid drum and bass element as an object on a sphere without a channel bed. |
| MPEG-H 3D Audio | Channels, objects and Higher Order Ambisonics in one stream, with optional listener control | MPEG-H 3D Audio allows listeners to adjust the level of the lead vocal or drum breaks if the producer allows it. |
| Auro-3D | Channel-based: a height layer above 5.1 or 7.1, with an optional overhead channel | Auro-3D uses fixed height channels rather than objects to lift the strings and pads above the drum break. |
| Eclipsa Audio (IAMF) | Channel-based and scene-based (Ambisonics) audio elements; no objects | Eclipsa Audio uses IAMF to carry the mix as channels or Ambisonics because it does not support audio objects. |
| Ambisonics | Scene-based: the whole sound field, decoded to any speaker layout or to headphones | Ambisonics stores the entire liquid drum and bass sound field as spherical harmonics to decode to any speaker layout. |
| ADM BWF | Open exchange file (ITU-R BS.2076 metadata in a BW64 file) for channels, objects and scenes | The ADM BWF master file carries all the channel and object metadata required for streaming liquid drum and bass. |
Delivery checklist for a liquid drum and bass 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 the binaural render on headphones to ensure the fast drum break remains punchy and the sub bass stays warm and centred.

Frequently asked questions
Does this guide cover atmospheric drum and bass, soulful drum and bass and jazzstep?
Yes. Atmospheric drum and bass pushes pads and textures wide and high around light breaks. Soulful drum and bass keeps the sung vocal front and close with keys and strings around it. Jazzstep places horns, vibes, piano and double bass like a small band around the listener.
Can I make a liquid drum and bass mix in Dolby Atmos or Eclipsa Audio?
Can I make a liquid drum and bass mix in Dolby Atmos? Yes, Dolby Atmos is the standard format for immersive music delivery to streaming services. You deliver an ADM BWF master at 48 kHz and 24-bit. Note that Apple Music applies its own spatial renderer, so its headphone result can differ from the Dolby binaural render and must be checked separately. Eclipsa Audio is a separate delivery because it uses IAMF, which has no objects.
Should liquid drum and bass elements be beds or objects in Dolby Atmos?
Should liquid drum and bass elements be beds or objects in Dolby Atmos? The fast kick, snare and warm sub bass should sit in the bed to keep the low end solid and phase coherent. Atmospheric pads and room reverbs also work best in the bed to wrap the listener. Use objects for the lead vocal, Rhodes keys, strings and percussion so you can place them precisely in the room and use binaural metadata for depth.
Does a liquid drum and bass Dolby Atmos mix also work for Sony 360 Reality Audio and MPEG-H?
Does a liquid drum and bass Dolby Atmos mix also work for Sony 360 Reality Audio and MPEG-H? No, they are different formats. Sony 360 Reality Audio is built on MPEG-H 3D Audio and is entirely object-based with no channel bed. Because a Dolby Atmos mix relies on a channel bed for the drum and bass foundation, you must create a separate mix for Sony 360 Reality Audio by placing every element as an object on a sphere.
Is spatial audio good for liquid drum and bass?
Yes. Liquid drum and bass is full of long, warm sounds that crowd a stereo mix. Spatial audio wraps them around the listener while the drums and sub stay tight.
How is liquid drum and bass different from drum and bass in spatial audio?
Liquid drum and bass needs more width and space for strings, keys and pads, and less movement. Heavier drum and bass styles focus on aggressive bass design and fast movement, with the sub and the bass at the centre of the mix.
Where should the vocal go in immersive liquid drum and bass?
Front and close, just off centre. Keep the main vocal fairly dry and let its echoes and harmonies drift around and behind the listener.
Can I convert a finished liquid drum and bass 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 liquid drum and bass work on normal headphones?
Yes. The mix is rendered binaurally, so the rolling drums and warm, wide harmony work on any regular headphones.
