Part of the series Spatial audio and immersive music by genre.

Nu metal took shape in the United States in the mid 1990s, when bands began to mix heavy, down-tuned riffs with hip-hop rhythms, funk bass and the moody textures of alternative rock and grunge. Korn's 1994 debut is usually treated as the starting point, and by the end of the decade the style dominated rock radio. The sound is built on seven-string guitars tuned very low, simple, syncopated riffs that lock to the kick, bass lines that are often slapped or detuned, and drum grooves borrowed from hip-hop at around 90 to 110 BPM. On top come rapped and sung vocals, DJ scratches, samples and electronic noise. That mix of a heavy band and hip-hop production is a strong fit for spatial audio. This guide covers how spatial audio for nu metal works, where to place each element and how to make an immersive nu metal mix. For the basics, see what spatial audio is.

Why nu metal works in spatial audio

Nu metal is really two records at once: a metal band playing a heavy, bouncing riff and a hip-hop production with scratches, samples and vocal layers. In stereo the DJ, the samples and the backing vocals are squeezed into the gaps between the guitars, and they often disappear when the riff kicks in. In an immersive mix the groove stays heavy in the middle, the guitars open up to the sides and the hip-hop layers get their own places around the listener.

The rule: a heavy groove in the middle, hip-hop detail around it. Kick, bass and the lead vocal never move, the guitars stay wide, and scratches and samples carry the motion.

Immersive music for nu metal: what listeners hear

• A groove that bounces in the centre. Kick, snare and bass hit together, heavy and mono.
• Low tuned guitars on both sides. Seven-string riffs surround the listener without clouding the bass.
• Scratches that cut across the room. The DJ moves around the front instead of hiding behind the guitars.
• Samples and noise overhead. Loops, synths and industrial textures drift above and behind.

Where to place each element in a nu metal mix

The psychoacoustics behind nu 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 nu metal.

• Kick and bass stay centred. The ear finds almost no direction in frequencies below roughly 80 to 100 Hz, so a very low tuned bass and kick gain nothing from being spread. Keeping them centred and mono keeps the bounce heavy on any system.
• Scratches split from the riff. The brain groups sounds into streams by pitch, timing and direction. This is auditory stream segregation (Bregman). Moving turntable scratches across the front right lets the ear follow them as a separate part rather than hearing them as noise on top of the guitars.
• Lead vocal and backing shouts apart. Two voices that share a frequency range mask each other far less when they arrive from different directions. This is spatial release from masking. Keeping the main rap in front and the gang shouts to one side means both stay clear in the loudest chorus.
• Samples and synths drifting above. The ear is more sensitive to sounds that seem to approach than to ones that move away, a looming bias shown by Neuhoff with rising tones. A rising sample or synth sweep that moves overhead and forward builds tension into the drop.

The immersion profile for nu metal

Low-end focus is at maximum because nu metal lives on very low tunings, a heavy bass guitar and a kick that drives the bounce. Movement is high because turntables, samples and electronic effects are part of the style and can travel freely. Width is high for the double-tracked guitars. Height and space sit in the middle, because most records are dry and punchy.

Tips for an immersive nu metal mix

1. Keep the low end mono. Kick, bass and the lowest guitar notes must stay identical from every direction.
2. Keep the groove still. The bounce comes from the drums, bass and guitars hitting together, so do not move them.
3. Let the DJ move. Scratches and sample stabs are the natural moving parts, so give them space to travel.
4. Keep the lead vocal dry and close. Rapped lines need to cut through, so avoid long reverb on them.
5. Open up the quiet sections. Moody, clean verses can use wider space and pads, then snap back for the heavy chorus.

Nu metal styles: rap metal, alternative metal and industrial metal

The core placement holds for every nu metal style: drums, bass and the lead vocal in the centre, guitars wide, effects around and above. What changes is how much hip-hop, melody or machine sound is in the mix.

Rap Metal

Rap metal grew from crossovers between hip-hop and hard rock in the late 1980s and early 1990s, with rapped vocals delivered over heavy, riff-driven bands. The vocal is the lead instrument, so keep it front and centre, close and dry, with doubles and ad libs just off to each side. Keep the guitars wide but simple, because the riff supports the rhythm of the words. Scratches and vocal samples can move across the front. Hold back on space: rap metal usually sounds best tight and in your face, like a band playing in a small room.

Alternative Metal

Alternative metal emerged in the late 1980s and early 1990s, mixing heavy riffs with unusual song structures, melodic vocals and influences from funk, grunge and art rock. It often has more melody and atmosphere than rap metal. Put the sung lead vocal front and centre, and spread harmonies and doubled lines around the front sides. Clean, effected guitars can move across the sides in quiet verses, then the heavy riff lands wide and still. Use more space and lateral reflections than in rap metal, and raise ambient guitars and pads in the bridges.

Industrial Metal

Industrial metal fuses metal guitars with drum machines, sequenced synths, sampled noise and distorted vocals, and it grew from the late 1980s industrial and metal scenes in North America and Europe. Its machine pulse should be locked in the centre with the kick and bass, so the groove stays mechanical and precise. Spread the guitars wide and place synths and noise loops raised behind, with some sweeping slowly overhead. Distorted vocal layers can sit slightly above the lead. Keep the main sequence still and let effects and noise do the moving.

Related styles such as groove metal and funk metal follow the same idea: lock the low end and the lead vocal, then give guitars, samples and effects their own place.

How to make immersive nu metal from stereo

Spatial9 can create spatial audio from a stereo track in a few steps:

1. Upload your stereo master or your stems.
2. Spatial9's AI separates and places each part, locking the kick, bass and lead vocal in the centre and sending the guitars, scratches and samples around you.
3. Preview it in binaural on headphones.
4. Export Eclipsa Audio, ADM, binaural or Ambisonics.
5. Publish a video. Create a YouTube-ready video with your immersive audio and publish it directly.

Frequently asked questions

Does this guide cover rap metal, alternative metal and industrial metal?

Yes. Rap metal keeps the rapped vocal close and dry in front over a tight band. Alternative metal adds sung harmonies, moving clean guitars and more space. Industrial metal locks its machine pulse in the centre and raises synths and noise loops behind and above.

Can I make a nu metal mix in Dolby Atmos or Eclipsa Audio?

Yes. The placements in this guide work for both. Spatial9 exports ADM, the standard file used by Dolby Atmos studios, as well as Eclipsa Audio for YouTube, so one immersive nu metal mix covers both. If you plan to release the Atmos version on Apple Music, build it from your original stems or multitracks, because Apple does not accept Atmos made from a finished stereo master. See where to publish spatial audio. You may also hear this called a 3D nu metal mix or nu metal in spatial audio.

Is spatial audio good for nu metal?

Yes. Nu metal layers a heavy band, vocals, scratches and samples. Spatial audio keeps the groove heavy in the centre and gives the hip-hop detail its own space.

How is nu metal different from metalcore in spatial audio?

Nu metal is slower and built on groove, with hip-hop drums, turntables and samples, so its mix uses more movement from the DJ and electronic layers. Metalcore is faster and built on breakdowns, double kick and screamed and clean vocals, so it needs a tighter centre and less movement around the band.

Where should the DJ and turntables go in an immersive nu metal mix?

Put the scratches at the front side, opposite the backing vocals, and let them move. Avoid leaving them behind the listener, because the scratch works as a lead instrument.

Can I convert a finished nu 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 nu metal work on normal headphones?

Yes. The mix is rendered binaurally, so the wide guitars, moving scratches and heavy low end work on any regular headphones.
