Immersive audio is a way of reproducing sound that places the listener inside the audio experience. Instead of sound coming only from in front of you or around you on a flat horizontal plane, immersive audio surrounds the listener in multiple dimensions — including above, and sometimes below — creating a far more realistic and engaging sense of space.

Immersive audio is also known as spatial audio, 3D audio, or 360° audio. While the terminology may differ, the objective is the same: to deliver sound with a convincing sense of envelopment, depth, and realism that traditional audio formats cannot achieve. 

From stereo to full immersion

Traditional audio formats have clear spatial limitations. Mono delivers sound from a single point, while stereo introduces width across the front of the listener. Surround formats such as 5.1 and 7.1 expand this experience by adding speakers around the listener — but still mainly at ear level.

Immersive audio introduces a vertical dimension, allowing sound to be placed above the listener as well as around them. This enables creators to design soundscapes that feel natural and three-dimensional, whether it’s the ambience of a concert hall, overhead effects in a film, or the subtle spatial movement of musical elements.

How immersive audio works

Immersive audio systems use multiple loudspeakers arranged in layers around the listening position. These typically include:

• Surround speakers at ear level
• Height speakers positioned above the listener
• One or more subwoofers for low-frequency content

Depending on the format, immersive audio can be channel-based or object-based. Object-based systems allow sounds to be treated as individual audio objects that can move freely within a three-dimensional space, adapting automatically to different speaker layouts. This flexibility helps ensure consistent playback across a wide range of listening environments.

Immersive audio formats

Several immersive audio formats are in use today, all aiming to deliver a convincing sense of space:

• Dolby Atmos – An object-based system widely used in cinema, broadcast, music production, and streaming.
• Dolby Atmos Music – Optimised for music distribution and streaming, supporting immersive playback on loudspeaker systems and headphones.
• Auro-3D – A channel-based, three-layer format that adds height and overhead channels.
• Sony 360 Reality Audio – An object-based music format designed to deliver a full 360-degree sound field.

Each format differs technically, but all rely on accurate monitoring and calibration to achieve reliable results. 

Monitoring immersive audio with Genelec

To experience immersive audio as intended, a carefully calibrated loudspeaker system in an acoustically well-designed room is essential. Genelec’s immersive monitoring solutions are designed to make this process accurate, scalable, and repeatable. 

Smart Active Monitoring (SAM™)

Genelec Smart Active Monitors and Subwoofers form the foundation of immersive monitoring systems. SAM systems allow precise control over level, distance, delay, and frequency response for each loudspeaker in the setup, ensuring consistent performance across complex multi-channel layouts.

GLM calibration software

GLM (Genelec Loudspeaker Manager) software plays a key role in immersive audio workflows. GLM measures the listening environment and automatically calibrates the entire system, compensating for room acoustics, speaker placement, and timing differences. This ensures that immersive mixes translate reliably to other playback systems, from cinemas to home environments and headphones. 

Aural ID® headphone monitoring

For creators who work with headphones as part of their immersive workflow, Aural ID provides a trusted solution. Aural ID creates a personalised headphone profile that allows seamless switching between loudspeaker monitoring and headphone listening, while maintaining spatial accuracy and tonal consistency. This is especially valuable when working in immersive formats where translation is critical. 

Why immersive audio matters

Immersive audio is rapidly becoming a standard across music, film, broadcast, and interactive media. As streaming platforms and playback devices increasingly support immersive formats, audiences now expect sound that feels realistic, engaging, and emotionally impactful.

With accurate monitoring, calibration tools like GLM, and technologies such as Smart Active Monitoring and Aural ID, immersive audio creators can work with confidence — knowing their mixes will translate as intended across all listening environments.
