Listeners can hear a difference between standard audio and better-than-CD quality, known as high-resolution audio, according to a new study published in the June issue of the Journal of the Audio Engineering Society (JAES) by Dr. Joshua Reiss of the Centre for Digital Music, Queen Mary University of London (QMUL).
The meta-study compared data from 18 studies involving 450 participants listening to samples of music in different formats. In total, the studies involved over 12,000 different trials where participants were asked to discriminate between formats. Overall, listeners could distinguish between the formats, especially if they had been trained to hear a difference. This is the first time that formal meta-analysis techniques have been applied to audio engineering research.
In addition to training, the research suggested that careful selection of stimuli, including use of long duration samples, may play an important role in the ability to discriminate. Studies that did not show an ability to discriminate were generally more prone to biases or flaws in their design. Reiss concluded that “the perceived fidelity of an audio recording and playback chain is affected by operating at a resolution higher than the CD standard.”
“Audio purists and industry should welcome these findings,” said Reiss. “Our study finds high-resolution audio has a small but important advantage in its quality of reproduction over standard audio content. Trained listeners could distinguish between the two formats around sixty percent of the time.” Dr. Reiss explained, “One motivation for this research was that people in the audio community endlessly discuss whether the use of high-resolution formats and equipment really makes a difference. Conventional wisdom states that CD quality should be sufficient to capture everything we hear, yet anecdotes abound where individuals claim that hi-res content sounds crisper, or more intense. And people often cherry-pick their favorite study to support whichever side they’re on.” He continued, “We gathered 80 publications in the field, and analyzed all available data, even asking authors of earlier studies for their original reports from old filing cabinets. We subjected the data to many forms of analysis. The effect was clear, and there were some indicators as to what conditions demonstrate it most effectively. Hopefully, we can now move forward towards identifying how and why we perceive these differences, and better experimental design.”
When asked about the type of content for which high-resolution recording and playback most made a difference, Dr. Reiss responded, “The jury is still out. The studies that most showed an effect mainly used jazz and classical music, but this wasn’t exclusive. We looked at lots of factors like choice of content and equipment. Results suggested that listeners often needed to listen to each sample for more than 30 seconds, but possible factors were mostly overshadowed by training test subjects in critical listening skills specific to the test, and in general, good experimental design.”

The inaugural AES International Conference on Audio for Virtual and Augmented Reality, to be held on September 30 and October 1, 2016, will be co-located with the 141st AES Convention at the Los Angeles Convention Center’s West Hall. The two-day program of technical papers, workshops, tutorials and a manufacturer’s expo will throw a unique spotlight on the creative and technical challenges of providing immersive spatial audio to accompany virtual-reality and augmented-reality media, which is demonstrably the fastest-growing section of the entertainment-audio markets. The deadline for Paper proposals has been extended to May 23rd for those who still wish to participate in this first-ever AES event.
The conference will attract content developers, researchers, manufacturers, consultants and students, in addition to audio engineers seeking to expand their knowledge about sound production for virtual and augmented reality. The companion Expo will feature displays from leading-edge manufacturers and service providers looking to secure industry metrics for this emerging field.
“Film director George Lucas once stated that sound represents 50% of the motion-picture experience,” considers co-chair Andres Mayo. “This conference will demonstrate that convincing VR and AR productions, using a variety of playback devices, require audio that follows the motions of the subject, and produce a realistic immersive experience. Our program will spotlight the work of leading proponents in this exciting field of endeavor, and how realistic spatial audio can be produced from existing game-console and DSP engines.”
The rich and varied conference program will provide an overview of the AR/VR creative process, applications workflow and product development, while creating an activity hub to focus attention on the expertise the Audio Engineering Society can offer these expanding creative communities. Costs range from $195 for a 1-Day Pass for AES members ($295 for a 2-Day Pass) and $125 for accredited students, to $280/$435 for non-members; early-bird discounts also are available.
Proposed topics include: Object-based Audio Mixing for VR/AR Applications; Immersive Audio in VR/AR Broadcast; Live VR Audio Production; Developing Audio Standards for VR/AR Applications; Cross Platform Audio Considerations in VR Applications; and Streaming Immersive Audio Content.

Experiencing Binaural Listening – recreating a 3D soundspace through headphones, which is an ever-expanding aspect of present-day audio – will be an integral component of the 140th AES Convention, coming to the Palais des Congrès in Paris June 4 to 7. France occupies a leading role in the research and the development of Binaural Listening (the BiLi project) due to both the remarkable research of Rozenn Nicol at Orange Labs (formerly France Telecom) and the growing demand for binaural listening in the Audio and Audio Visual market. Rozenn is also the author of a fascinating AES Monograph on Binaural Technology.
During the Technical Program at the 140th AES Convention, many of the groups participating in the BiLi project in France will be present (Orange Labs, France Televisions, CNSMDP – Conservatoire de Paris, IRCAM, Radio France, Arkamys, Trinnov, a-volute, CNRS-LIMSI). One of the workshop rooms will be completely equipped with headphones so attendees can hear a Binaural Listening experience first hand. Radio France, under the responsibility of Edwige Roncière and Hervé Desjardin, have also produced a remarkable amount of program material for both 5.1 Multichannel and Binaural Listening. This important research and development work will be presented in Workshops, and through special activities devoted to Audio Projection, in Multichannel and with Binaural Listening.
