Build the perfect Dolby Atmos Studio with HEDD Audio
Over the past few years, HEDD has been working with engineers and studios of all sizes to help them realise a professional immersive audio installation that can live up to their dreams. Creating or upgrading an existing professional studio to be immersive ready is a challenge that requires considering a range of issues including acoustic treatment, physical layout, mounting and cabling, calibration, and the software and hardware chain.
Dolby Atmos is a surround sound technology, and associated audio format, designed to create a highly immersive experience. It was developed by Dolby Laboratories and first debuted in 2012 in cinemas before being expanded to both home and professional audio use.
The latest in a long line of new audio technologies promoted as having the potential to revolutionise how music is heard, Dolby Atmos has so far proven its worth by bringing a three-dimensional depth to surround sound (itself a revolutionary new standard that has seen multiple evolutions over the past 50 years, including 5.1 and 7.1). This is because Dolby Atmos focuses on object-based mixing, as opposed to channel-based, which allows sounds to be distributed independently in a three-dimensional space and mixed only at the reproduction stage, rather than assigned to an output channel. The result is a significant step towards a realistic, immersive audio experience compatible with a growing range of playback systems, from headphones to home systems.
Today, Dolby Atmos has become the main standard for immersive audio with new products and companies offering support for the format including major players in music streaming such as Apple, Tidal, and Amazon. As a result, the professional audio world has had to adjust with many studios deciding to take immersive audio more seriously and upgrade their studio installations or even dedicate themselves entirely to it.
Within the realms of audio consumption and production, Atmos is ideal for the following:
- Bring listeners closer to the real-life concert experience by simulating room reflection effects and the spatial movement of sound.
- Allow artists to compose or perform music in a 3-dimensional space.
- Spatialise existing stereo mixes, turning them into Atmos mixes.
A traditional 7.1.4 setup is physically represented in monitors as follows:
- The 7 ear level monitors cover three front row channels (left, centre, right) and four rear surround channels.
- The 4 ceiling level monitors cover front and rear channels for both left and right sides.
- At least 1 subwoofer located on the floor covers the low frequency range.
The HEDD approach to immersive audio - Right in Time
At HEDD we think that immersive audio offers incredible potential for exploring new ways to fully enjoy listening to music, film, or even video games.
To ensure that a multichannel Atmos setup translates to the listener in the most transparent and emotional way, the time relationships between monitors must stay correct at all times and independent from the room acoustics and geometry.
It’s an accepted truth of professional audio that due to their frequency-dependent behaviour, loudspeakers show deviation in their phase response. In practical terms this means that lower frequencies, such as bass, travel slower through the speakers than the middle and high frequencies regardless of whether or not a monitor is active or passive. This creates a distortion of the time relationships between frequencies and therefore affects how the audio coming out of the speakers is heard.
HEDD has focused on solving this common issue with the HEDD Lineariser®, a DSP-enabled tool available in all our MK2 monitors. The Lineariser is an adapted Finite Impulse Response (FIR) filter that restores the original time relationships of the frequencies in the incoming signal within the monitor at the cost of some latency. As a result the transient response is improved and a better focused stereo localization achieved.
We call this approach Right in Time because we believe that the importance of accurate time relationships is essential to ensuring a truly immersive audio experience. To be right in time across all frequencies is key in a Dolby Atmos setup where you have multiple monitors placed in a physical space (beneath, around, and above you) as well as multiple audio objects located within a three-dimensional space. When perfectly aligned, audio objects in your Atmos mix will be sharper as the relationships within and between all monitors in the room are 100% accurate and therefore more natural.
Thanks to the innovative functionalities of our MK2 range such as the Lineariser and Closed or Ported, HEDD monitors give audio professionals the ability to precisely control the linear phase response, a key but often undervalued element of audio reproduction.
