Listening Test Data Analysis for Everyone: An A/B Test for Car Audio

May 26, 2021 3:00pm ‐ May 26, 2021 3:45pm

Listening evaluations are EVERYWHERE. Whether involved in the creative process, design of gear or selection of components, gear or suppliers, audio is being judged by humans! These evaluations might be informal, perhaps one of many taken on a given day. However, oftentimes, formal listening tests are performed to support business decisions: When the stakes are high, it is often prudent to gather scientific, valid data about the test scenario. In each instalment of the series, HARMAN's data analysis expert Dr. Darlene Williamson will take you through data analytic procedures for a specific type of test. Test design considerations will be covered, but the focus will be on valid data analytic strategies for formal listening tests. Students and professionals alike will benefit from Dr. Williamson’s careful and thorough explanations on the pitfalls to avoid and options to navigate when extracting the meaning from the data. The series begins with probably the most common type of listening test: the A/B Test, which aims to see which of two options are preferable. Analyses from real-world datasets will be showcased, using commonly available software tools. Everyone is invited to come along and give their stats skills a boost!


Audio Mythology, Human Bias, and How Not To Get Fooled

May 26, 2021 3:00pm ‐ May 26, 2021 3:45pm

As a spiritual successor to his infamous 2009 "Audio Myths Workshop" session, audio engineer, author and mythbuster Ethan Winer will be joined by Live Sound International technical editor Michael Lawrence to discuss what he has learned from a long career dedicated to investigating and debunking widely held audio-related misconceptions and mythology. Winer and Lawrence will touch on some common audio "truisms" that might not be as true as they seem, along with the perceptual biases that can skew our experiences as listeners, and talk about the "sandbox" approach to designing simple experimentations to test and investigate claims for oneself.


Modern Digital to Analogue Converters: HOW many bits!?

May 26, 2021 1:00pm ‐ May 26, 2021 2:00pm

Recently Digital to Analogue Converters (DACs) that claim to have resolutions of 32 bits have become available. How do they possibly achieve such exalted levels of performance? Almost all, modern Digital to Analogue convertors (DACs) use oversampled multi-bit convertors with noise-shaping to achieve their high performance. Oversampling and noise-shaping allow one to use a DAC with a small number of levels, which is easier to manufacture. Unfortunately traditional noise shaping does nothing to reduce the effect of component tolerances in the DAC, because the analogue output cannot be fed back to the input. However, modern DACs do manage to noise shape the output from the DAC without any feedback. This piece of audio alchemy is critical to the exceptional performance of modern Digital to Analogue convertors. This Tutorial will explain how this alchemy is achieved. It will review the problems of component tolerance in DACs and show how they compromise performance. Then noise-shaping, and how it can be applied, without magic, or knowing the actual converted output, to a practical DAC will be explained. It will conclude by discussing how system aspects may limit their performance and discuss how you might prepare audio signals to maximise converter performance.

Next generation audio for advanced music creations and distributions

May 26, 2021 12:00pm ‐ May 26, 2021 1:30pm

Immersive audio, high-resolution audio, and high-definition audio have become available for recording, creations, and online delivery the music. While the lossy codec such as MPEG4-AAC was the key technologies to enable digital broadcasting and online-delivery, viewers and listeners of digital broadcasting and online-delivery have become noticed the difference of audio quality and musical emotion between the legacy 2ch stereo audio using lossy codec and immersive audio using high-quality audio codec. This workshop will introduce recent actual use cases of next generation audio such as immersive audio, high-resolution audio, and high-definition audio for the advanced music creations and online-delivery of music. Kimio Hamasaki will summarize the history and latest status of next-generation audio and introduce examples of his own researches and development as well as his musical recording works. Hideo Irimajiri will report on the live experiment of music online-delivery with high-resolution audio and immersive audio in Japan done by WOWOW last October and discuss the future prospects. Toru Kamekawa will report on music creations using next-generation audio at the Tokyo University of the Arts and introduce some actual examples and discuss the future prospects. Kazuya Nagae will report on the recent productions, distributions and education using immersive audio at Nagoya University of the Arts and discuss the future prospects. These panels will also discuss the advantages of the next-generation audio for advanced music creations and online-delivery and issues of those they encountered during the actual cases. And finally, they will discuss how to improve the quality and emotion of music recordings and deliveries in the future.


Loudspeaker Virtualization for Immersive

May 26, 2021 11:00am ‐ May 26, 2021 12:00pm

Immersive Sound offers consumers an extremely immersive listening experience for music through loudspeakers, which is not possible with standard 2CH stereo. Large loudspeaker setups such as Auro 3D 13.1 or Dolby Atmos 9.1.6 are not feasible for most consumers at home. It therefore makes sense to offer the content as headphone productions for the mass market. A large number of binauralization processors and consumer products have entered the headphone market in recent years. And streaming services have been offering Immersive Sound content for headphones since 2019. But how close does headphone reproduction come to reproduction via loudspeakers? And what needs to be done still to make headphone reproduction equal? In his video workshop, Lasse Nipkow explains the most important aspects of loudspeaker virtualization, which are necessary for a three-dimensional headphone reproduction. He uses video animations and sound samples to show where we are today on the way to this goal.

The Sound of Things

May 26, 2021 10:00am ‐ May 26, 2021 11:00am

Psychoacoustic6s has been gradually making its way from lecture halls and academic papers to the everyday life of NVH (Noise, Vibration and Harshness) and sound quality engineers worldwide. The competitive situation in the market calls for new products to not only function better, but to sound better too. In this tutorial I would like to present how sound quality analysis tools, such as subjective listening tests or objective analyses (including calculations of loudness, sharpness, modulation or tonality) are used during the product development process. The presented examples will link the intricacies of the human auditory system to different acoustic challenges that arise during the design phase. From toothbrushes, through espresso machines and vacuum cleaners up to cars and airplanes, if the thing makes a sound, there’s a big chance that someone used the psychoacoustic theory to evaluate and improve it.
