Spatial Audio & Immersive Music for Metal: Heavy Metal, NWOBHM, Glam & Groove Metal
Spatial9 Team · · Updated · 15 min read
Part of the series Spatial audio and immersive music by genre.
Key takeaways
- Immersive metal keeps the impact in front, with rhythm guitars forming a wide wall and kick, snare and vocal centred.
- Raising cymbals is described as the fastest way to clean up a crowded metal mix.
- In metal, solos can move but riffs should not, because a moving riff feels unstable.
- Metal low end should stay mono and centred so fast kick patterns read, and the profile rates low-end focus 5 out of 5.
Metal is one of the densest genres to mix. Down-tuned guitars, fast double kick, bass, screaming or clean vocals and crashing cymbals all fight for the same frequencies. In stereo, the usual fix is to squeeze and compress. Spatial audio offers another option: give parts more room, so the mix gets heavier without turning to mud. This guide covers how spatial audio for metal works, where to place each element and how to make immersive metal music from a stereo master. For the basics, see what spatial audio is.
Why metal benefits from spatial audio
The biggest problem in a metal mix is masking: parts hiding each other. Spatial audio reduces masking by separating sounds in direction and height, not just in frequency. Cymbals moved overhead stop covering the guitars. A wide guitar wall stops covering the vocal.
The rule is to keep the impact in front. Metal should feel like a stage in front of you, with the room and the crowd around you, not like instruments flying past your head.
Immersive music for metal: what listeners hear
- A wall of guitars. Double-tracked rhythm guitars spread wide in front feel massive.
- Kicks that hit. The double kick stays centred and tight, so fast patterns stay clear.
- Cymbals that do not cover everything. Lifting them overhead frees the midrange for guitars and vocals.
- A room you are standing in. Room microphones, choirs and orchestral layers around and above make the track feel live.
Where to place each element in a metal mix
| Element | Position | Height | Why it works |
|---|---|---|---|
| Lead vocal | Front centre | Ear level | Stays clear over the guitars |
| Rhythm guitars | Wide front left and right | Ear level | Creates the wall of sound |
| Kick drums | Centre | Ear level | Tight, fast and focused |
| Snare | Front centre | Ear level | Punch and focus |
| Cymbals | Front, spread | Raised | Reduces masking of guitars |
| Bass guitar | Centre | Ear level | Glue between kick and guitars |
| Lead solo | Side, can move | Ear level | A moment of motion |
| Room, choir, orchestra | Behind and sides | Raised | Size and atmosphere |
The psychoacoustics behind metal placement
Every position in the table above follows how the ear and brain locate sound. Here is the reason behind the main choices for metal.
- Rhythm guitars wide left and 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. The wall of guitars stays massive without masking the vocal in the middle.
- Kick drums and bass guitar centred. In real rooms and on most playback systems, sub-bass below roughly 80 to 100 Hz gives the brain very little usable direction, which is why a single subwoofer can serve a whole speaker layout. Fast double kicks need a rock-solid, unmoving low end to stay tight.
- Lead solo at the side, free to move. 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. A slow move during a solo is easy to follow and adds drama.
- Room, choir and orchestra behind and at the sides. Concert hall research shows that reflections from the sides, not from the front, create the sense of width and of being surrounded (Barron and Marshall, 1981). Side and rear layers add epic scale without crowding the band.
The immersion profile for metal
Metal scores highest on low-end focus and width. Movement stays low: only solos and occasional effects should travel. Space should be short and punchy, except in symphonic or atmospheric styles where choirs and orchestras add a bigger hall.
Tips for an immersive metal mix
- Keep the low end mono and centred. Kick and bass must stay locked for fast patterns to read.
- Go wide with rhythm guitars, not with everything. Width is most powerful when it belongs to the guitars.
- Lift cymbals. Raising them is the fastest way to clean up a crowded metal mix.
- Let solos move, not riffs. A moving solo is exciting. A moving riff feels unstable.
- Use the back for the room. Room sound behind and above the listener makes the track feel like a live show.
Metal styles: heavy metal, NWOBHM, glam and groove metal
The core placement from this guide still applies to every style: a wide wall of rhythm guitars, kick, snare, bass and vocal centred, and cymbals raised. Here is what changes from one style to the next.
Heavy metal
Heavy metal is built on distorted riffs, powerful drums, soaring vocals and guitar solos. Keep the rhythm guitars wide at front left and right and the lead vocal clear at front centre. This is the style where the lead solo can move a little along the side, while the riffs stay fixed. Use a short room, and lift choir or orchestra parts behind and above only when the song calls for them.
NWOBHM
The new wave of British heavy metal is faster and rawer, with galloping rhythms and twin guitar harmonies. Place the two harmony leads on opposite sides, one left and one right, so each line is easy to follow. The galloping bass and kick stay locked in the centre. Keep the room short and the production a little drier and more live-sounding than modern metal.
Glam metal
Glam metal is polished and catchy, with big choruses, layered backing vocals, flashy solos and large-sounding drums. Spread the backing vocals wide to the sides and slightly behind so the chorus feels huge. Allow a little more room on the snare than in other metal styles, but keep it controlled. The rhythm guitars stay wide and still, and the solo can move briefly at the side.
Groove metal
Groove metal is mid-tempo and heavy, with chunky, syncopated, down-tuned riffs and harsh, shouted vocals. Tightness is everything, so keep the low end mono and centred and the room very short. Push the rhythm guitars to full width and keep them completely still. Raised cymbals matter here, as they keep the thick riffs clear. Solos are rarer, so movement can be almost zero.
The same approach works for hair metal, modern metal and Christian metal. Hair metal follows glam metal. Modern metal often adds synths or samples, which sit well behind and raised. Christian metal is defined by its lyrics rather than one sound, so follow whichever style the band plays.
Dolby Atmos and object-based mixing for metal
Dolby Atmos mixes metal using a channel bed for the foundation and objects placed anywhere in the room for precision. Most listeners will hear the result on headphones through binaural rendering on Apple Music, Tidal or Amazon Music. Spatial9 helps you plan these placements for every format. A good Atmos mix gives dense metal arrangements the space they need, separating the heavy guitars from the drums and vocals so everything hits harder.
How the Atmos plan differs from the placement map. This Atmos plan differs from the Ambisonics map to suit metal mixing practices. The map placed the kick drums and bass guitar behind the listener, but Atmos requires low-end foundations in the front bed. The rhythm guitars are pulled closer to the centre line to act as main leads. The snare is moved to the centre for focus. The room and choir are spread across a full bed rather than sitting in a single rear position.
Beds and objects for each metal element
| Element | Atmos role | Where it plays in 7.1.4 | Binaural mode | Why |
|---|---|---|---|---|
| Lead vocal | Object | Ear level, front of the room, centre (X 0, Y 0.7, Z 0) | Near | Keeps the vocal focused and upfront over the dense guitars. |
| Rhythm guitar | Object, small size | Ear level, front of the room, left (X -0.35, Y 0.6, Z 0) | Mid | Creates a thick wall of sound while leaving the centre clear. |
| Rhythm guitar | Object, small size | Ear level, front of the room, right (X 0.35, Y 0.6, Z 0) | Mid | Mirrors the left guitar to balance the heavy rhythm section. |
| Kick drums | Bed | Centre plus LFE (C + LFE) | Off | Anchors the fast double kick in the centre with solid low end. |
| Snare | Object | Ear level, front of the room, centre (X 0, Y 0.6, Z 0) | Mid | Pulls the snare slightly off the wall for depth and punch. |
| Cymbals | Object, medium size | Overhead, front of the room, left (X -0.3, Y 0.5, Z 0.8) | Mid | Lifts harsh frequencies away from the guitars and vocals. |
| Bass guitar | Bed | Centre plus LFE (C + LFE) | Off | Locks with the kick drum to provide a steady foundation. |
| Lead solo | Object, moving | Ear level, front of the room, right (X 0.5, Y 0.5, Z 0). Moving: Arcs upwards and outwards during the solo to add excitement, ending at raised, front of the room, right | Near | Draws attention to the solo without masking the rhythm guitars. |
| Room / choir | Bed | Whole 7.1.2 bed | Far | Wraps the listener in a large acoustic space for epic scale. |
Dolby Atmos settings for metal
- LFE. Route the kick and bass to the LFE channel through the bed, as objects have no LFE send.
- Object size. Keep lead vocals and solos as point sources for focus, but increase size for cymbals to spread them.
- Height use. Reserve the height channels for cymbals, reverbs and choirs to avoid losing punch on the drums.
- Binaural modes. Set the kick and bass to off for a solid centre, and use mid or far for guitars.
- Rhythm guitars. Keep the main rhythm guitars near the centre line to maintain their role as the driving lead.
Metal across immersive formats
| Format | How it carries sound | What it means for metal |
|---|---|---|
| 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 a channel bed and objects, allowing precise placement of metal vocals and solos. |
| Sony 360 Reality Audio | Object-based, built on MPEG-H 3D Audio: every sound is an object on a sphere | Sony 360 Reality Audio uses only objects on a sphere, meaning the metal bed channels must be converted to objects. |
| 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, letting broadcasters offer interactive metal mixes where listeners can adjust the vocals. |
| Auro-3D | Channel-based: a height layer above 5.1 or 7.1, with an optional overhead channel | Auro-3D relies on fixed height channels rather than objects, so overhead metal cymbals are routed to the upper speaker layers. |
| Eclipsa Audio (IAMF) | Channel-based and scene-based (Ambisonics) audio elements; no objects | Eclipsa Audio uses IAMF which lacks objects, so your Atmos metal mix is rendered to channels or Ambisonics for delivery. |
| Ambisonics | Scene-based: the whole sound field, decoded to any speaker layout or to headphones | Ambisonics captures the whole sound field as a scene, perfect for storing the dense, enveloping room sound of a metal gig. |
| ADM BWF | Open exchange file (ITU-R BS.2076 metadata in a BW64 file) for channels, objects and scenes | ADM BWF is the standard open metadata file format used to deliver your finished Dolby Atmos metal mix to streaming services. |
Delivery checklist for a metal 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 Apple Music spatial renderer on headphones to ensure the rhythm guitars do not lose their heavy impact.
How to make immersive metal music from stereo

Frequently asked questions
Does this guide cover heavy metal, NWOBHM, glam and groove metal?
Yes. All four keep the rhythm guitars wide and still, with kick, snare, bass and vocal centred and cymbals raised. Heavy metal lets the solo move a little at the side. NWOBHM places twin harmony leads left and right with a drier room. Glam metal spreads backing vocals wide with slightly more room. Groove metal is the tightest, with a very short room and almost no movement.
Can I make a metal mix in Dolby Atmos or Eclipsa Audio?
Can I make a metal mix in Dolby Atmos? Yes, Dolby Atmos is excellent for metal because it creates space for dense arrangements. You deliver an ADM BWF master to streaming services. Remember that Dolby Atmos and Eclipsa Audio are separate deliveries, as Eclipsa uses IAMF and has no objects. Always check your mix using the Apple Music spatial renderer, as its headphone result can differ from the standard Dolby binaural render and might change how your guitars sound.
Should metal elements be beds or objects in Dolby Atmos?
Should metal elements be beds or objects in Dolby Atmos? Use beds for your foundation and objects for precision. The kick drum, bass guitar and room reverbs work best in the bed, allowing you to route low frequencies to the LFE channel. Lead vocals, rhythm guitars, snares and cymbals should be objects. This lets you pull the guitars slightly off the front wall for depth and lift the cymbals into the height channels to stop them masking the midrange.
Does a metal Dolby Atmos mix also work for Sony 360 Reality Audio and MPEG-H?
Does a metal Dolby Atmos mix also work for Sony 360 Reality Audio and MPEG-H? Not directly. While Dolby Atmos uses a hybrid of a channel bed and objects, Sony 360 Reality Audio is entirely object-based and built on MPEG-H 3D Audio. It has no channel bed. To translate your metal mix, you must convert your bed tracks, like the kick and bass, into static objects placed around the listener sphere.
Is spatial audio good for metal?
Yes. Spatial audio reduces masking in dense metal mixes, so guitars sound bigger while vocals and drums stay clear.
Where should rhythm guitars go in an immersive mix?
Keep double-tracked rhythm guitars wide in front. They should feel like a wall in front of the listener, not wrap all the way around.
Should double kick drums move in spatial audio?
No. Keep the kick drums centred and steady so fast patterns stay tight and readable.
Can I convert a finished metal 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 metal work on regular headphones?
Yes. Devices render the mix binaurally, so the 3D effect works on any regular headphones.
