Spatial Audio & Immersive Music for Hardgroove: Complete Guide
Spatial9 Team · · Updated · 13 min read
Part of the series Spatial audio and immersive music by genre.
Key takeaways
- Immersive hardgroove keeps the kick and bass stabs punchy and centred while percussion loops move around the listener.
- The hardgroove rule is dry and punchy beats big and washy, so reverb stays short to keep the kick and loops tight.
- Moving percussion loops in hardgroove should be tied to a bar or beat so the motion feels like part of the groove.
- Hardgroove scores movement 4 but space only 2 out of 5, with a single short room used to glue the loops together.
Hardgroove is fast, percussive and raw. It is techno built from looping drums, funky samples and a relentless swing, made for long DJ sets. In stereo, those loops stack on top of each other. In spatial audio, each loop can come from a different direction, so the groove gets more complex without getting messier. This guide covers how spatial audio for hardgroove works, where to place each element and how to make an immersive hardgroove mix. For the basics, see what spatial audio is.
Why hardgroove works in spatial audio
Hardgroove is mostly rhythm. Percussion, rides, claps and chopped samples play interlocking patterns. Spreading them around the listener makes the groove feel like a spinning machine, which suits the genre perfectly.
The rule: dry and punchy beats big and washy. Keep reverb short so the kick and loops stay tight.
Immersive music for hardgroove: what listeners hear
- A kick that punches. Dry, centred and hard.
- Loops that spin. Percussion travels around the listener in time with the groove.
- Funk from behind. Chopped samples and claps add swing from the back of the room.
- A raw room. A short, tight room sound replaces long reverbs.
Where to place each element in a hardgroove mix
| Element | Position | Height | Why it works |
|---|---|---|---|
| Kick | Front centre | Ear level | The relentless drive |
| Bass stab | Centre | Ear level | Punch with the kick |
| Percussion loop | Front left, moving | Ear level | Spinning groove |
| Ride | Front right | Raised | Bright drive above |
| Funk sample | Behind left | Ear level | Swing and character |
| Claps | Behind right | Ear level | Rhythm from the back |
| Room | Behind | Raised | Short, raw space |
The psychoacoustics behind hardgroove placement
Every position in the table above follows how the ear and brain locate sound. Here is the reason behind the main choices for hardgroove.
- Kick and bass stab 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 driving groove depends on a low end that never wavers.
- Percussion loop moving on the front left. Moving sounds grab attention because the brain is wired to track change, so motion works best when it is slow, deliberate and kept away from the anchor parts. Slow movement keeps a looping part interesting without breaking the groove.
- Percussion left, ride right. When two sounds share a frequency range, separating them in direction makes each one easier to hear. Researchers call this spatial release from masking, the same effect that lets you follow one voice at a busy party. Two busy top-end loops stay separate when they come from opposite sides.
- Room behind. Thanks to the precedence effect, early reflections from a room do not pull a source sideways. They are heard as size and space around it. A short room sound adds warehouse energy without blurring the drums.
The immersion profile for hardgroove
Hardgroove scores high for movement and width but low for height and space. It is a genre of punch and drive, not atmosphere.
Tips for an immersive hardgroove mix
- Move loops in time. Tie each movement to a bar or beat so it feels like part of the groove.
- Keep the kick bone dry. No long tails on the low end.
- Spread loops, not layers of the same sound. Each direction should have its own pattern.
- Use one short room. A tight, shared space glues the loops together.
- Check the swing. Moving percussion must never drift off the beat.
Dolby Atmos and object-based mixing for hardgroove
Dolby Atmos mixes hardgroove using a channel bed for the foundation and objects placed anywhere in the room for precise positioning. Most listeners will hear the result on headphones through binaural rendering on services like Apple Music, Tidal and Amazon Music. Because each platform handles spatial audio differently, careful planning is essential. Spatial9 helps you plan placements for every format, ensuring your hardgroove tracks retain their punch and drive whether played on a massive club system or standard earbuds.
How the Atmos plan differs from the placement map. This Dolby Atmos plan moves the bass stab from behind to the front centre bed, as low frequencies must stay solid and phase coherent. The room sound is spread across the full bed rather than placed as a single raised source behind the listener, creating a more enveloping warehouse space. The funk sample and claps remain in the rear half of the room, but are pulled slightly forward to connect better with the front stage.
Beds and objects for each hardgroove element
| Element | Atmos role | Where it plays in 7.1.4 | Binaural mode | Why |
|---|---|---|---|---|
| Kick | Bed | Centre plus LFE (C + LFE) | Off | Anchors the relentless hardgroove drive solidly in the centre. |
| Percussion loop | Object, small size, moving | Ear level, front of the room, left (X -0.6, Y 0.5, Z 0). Moving: Travels slightly along the left wall to add spinning motion, ending at ear level, front of the room, left | Mid | Keeps the busy rhythm clear of the centre kick. |
| Ride | Object, small size | Raised, front of the room, right (X 0.6, Y 0.5, Z 0.5) | Mid | Separates high frequencies from the percussion loop for clarity. |
| Funk sample | Object, medium size | Ear level, rear of the room, left (X -0.6, Y -0.5, Z 0) | Mid | Adds swing and character from the rear left. |
| Bass stab | Bed | Centre plus LFE (C + LFE) | Off | Keeps low frequencies solid and phase coherent with the kick. |
| Claps | Object, small size | Ear level, rear of the room, right (X 0.6, Y -0.5, Z 0) | Mid | Provides a rhythmic answer from the back right. |
| Room | Bed | Whole 7.1.2 bed | Far | Glues the dry loops together in a shared warehouse space. |
Dolby Atmos settings for hardgroove
- LFE and bass. Low end placed as an object relies on playback bass management. Keep the kick and bass stabs in the bed and route them to the LFE channel for consistent club impact.
- Object size. Use the size control to spread objects across more speakers. Keep hardgroove percussion objects small for precise rhythms, but increase size slightly for funk samples to make them feel wider.
- Height use. Reserve the height channels for the ride cymbal and room ambience. Placing dry rhythmic parts fully overhead causes them to lose focus on headphones and in stereo fold-downs.
- Binaural render modes. Set the kick and bass to off so they remain solid and centred on headphones. Use mid for percussion loops and far for the room bed to create depth.
- Movement. Automate object positions sparingly. Moving a percussion loop slowly along the side wall adds a spinning feel without distracting from the core hardgroove rhythm.
Hardgroove across immersive formats
| Format | How it carries sound | What it means for hardgroove |
|---|---|---|
| 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 using up to a 7.1.2 channel bed and objects to place hardgroove elements precisely. |
| 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, so every hardgroove element becomes 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 and objects, allowing listeners to adjust the level of specific hardgroove loops if permitted. |
| Auro-3D | Channel-based: a height layer above 5.1 or 7.1, with an optional overhead channel | Auro-3D relies entirely on fixed channels with a height layer, meaning hardgroove height comes from channels rather than objects. |
| Eclipsa Audio (IAMF) | Channel-based and scene-based (Ambisonics) audio elements; no objects | Eclipsa Audio uses IAMF which lacks audio objects, so an Atmos hardgroove mix must be rendered to channels or Ambisonics. |
| Ambisonics | Scene-based: the whole sound field, decoded to any speaker layout or to headphones | Ambisonics stores the entire hardgroove sound field as spherical harmonics, ready to be decoded 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 file format used to deliver your finished hardgroove mix to streaming services. |
Delivery checklist for a hardgroove 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.
Ensure your integrated loudness is no higher than -18 LKFS and true peak is no higher than -1 dBTP before delivering your hardgroove master.

Frequently asked questions
Can I make a hardgroove mix in Dolby Atmos or Eclipsa Audio?
Yes, you can make a hardgroove mix in Dolby Atmos. The format allows you to keep the kick and bass punchy in the channel bed while placing percussion loops as objects around the room. Note that Dolby Atmos and Eclipsa Audio require separate deliveries, as Eclipsa uses IAMF and does not support objects. Additionally, Apple Music applies its own spatial renderer, so you must check its headphone result separately from the standard Dolby binaural render.
Should hardgroove elements be beds or objects in Dolby Atmos?
Hardgroove requires a solid foundation, so the kick, bass stab and room reverb should be routed to the channel bed. The bed anchors the low end and provides a consistent warehouse space. Percussion loops, rides, funk samples and claps should be objects. Using objects for these elements allows you to pull them off the walls for depth, separate them for clarity and add subtle movement to create the spinning groove that defines the genre.
Does a hardgroove Dolby Atmos mix also work for Sony 360 Reality Audio and MPEG-H?
A Dolby Atmos mix does not translate directly to Sony 360 Reality Audio or MPEG-H without adjustments. Sony 360 Reality Audio is entirely object-based and lacks a channel bed, meaning your hardgroove kick and bass must be converted to objects. MPEG-H supports both channels and objects, but is primarily used in broadcasting and allows user interaction. You will need to create separate masters using the specific authoring tools for each format to ensure the groove translates correctly.
Is spatial audio good for hardgroove?
Yes. Hardgroove is built from interlocking percussion loops, and spreading them around the listener makes the groove clearer and more driving.
Should hardgroove use a lot of reverb in 3D?
No. Keep the space short and dry. Hardgroove gets its energy from punch, not from long tails.
Should percussion loops move?
Yes, in time with the groove. Movement locked to the beat makes the loops feel like they spin around you.
Can I convert a finished hardgroove 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 hardgroove work on normal headphones?
Yes. The mix is rendered binaurally, so the spinning loops work on any regular headphones.
