What is #multimodal audio, and why does it matter? As humans, we perceive the world through multiple senses simultaneously, which is termed multimodal perception. This involves combining information from different senses, such as sight, hearing, and touch, in the brain. This process enables us to perceive and react to stimuli in our environment, allowing us to construct the reality we experience. Audio is naturally multimodal, as our body can understand audio information not just through our ears, but also through our skin, organs, etc. This is why you can simultaneously hear and feel as a car passes by you, informing your brain of the event. However, audio technology to date has primarily focused on each sense individually, limiting experiences and reaching maturity in reproduction methods: Acoustics: Generating sound optimized for using our ears to understand audio information. Haptics: Generating vibrations or movements felt on the skin or muscles, often used to convey information in an on/off signal using low-frequency vibrations. Tactile: Generating sound that can be perceived through touch, typically in low frequency, like a subwoofer attached to your body. So, why not create a method of understanding all audio information from one source, the way we perceive the real world, by encompassing the entire range of audio our body understands through vibration - Embodied Sound. This is why at EDGE Sound Research we invented Embodied Sound technology, which transforms ordinary objects into high-fidelity sound sources that you can hear and feel – all within a comfortable speaker-less environment. Our Embodied Sound Demo Pod is the first vessel to give us a glimpse of what this multimodal future can be, so enjoy as we walkthrough our Demo Pod at #CES2024.

Over the years at EDGE Sound Research, we've worked hard to design, test and build, with the conviction that what we are doing is fundamentally changing our relationship with sound and reality. But it's not enough to just know we've built something cool, our job is to allow others to dream with us. The Pod embodied the best of our ideas in a way that someone can intuitively understand and, as a prototype, sets the stage for realizing our vision of the nth degree of experiences. We are excited to share this vision with our partners and invite them to build with us together. One of the greatest joys of working at EDGE is without a doubt the passion that each and everyone exudes. They inspire me to do crazy stuff like this The Pod is certainly ambitious in terms of time and resource but I'm thankful for the faith and trust Valtteri Salomaki and Ethan Castro, PhD as well as the team had in me. Our starting point was the content, the story we wanted to tell and worked backwards on how to best tell the story with physical space. It was designed and fabricated in 1.5 months. We found a place, test built and tuned it in 2 weeks. Broke it down in 4 huge pallets and shipped to CES where we built it back up in 3 days. We then did that again in Indianapolis Gainbridge Fields in 3 days. It validated our intent to make something immersive, sturdy, modular, portable, and upgradable. Version 2 variations are already in the works! I can't wait to build with our partners to imagine the future we know is coming, and more exciting things coming soon. First Fundamental

IS #CLASS-D #AMPLIFICATION NOW #BETTER THAN #CLASS-A/B AND #CLASS-A? Robert Schryer | May 7, 2024 A couple of years ago, a #designer of high-end tube equipment said something to me that left such an impact it eventually led me, now that the conditions seem right, to write this article. That mind-bomb was set off when I asked the designer if he’d ever consider making a class-AB amp. Shaking his head, he replied that he wouldn’t, because in his view class-AB couldn’t convey the soul of the music like a tube amp could. After a pause, he added: “But I believe class-D might be able to do so one day. When that happens, I might consider building a class-D amp.” So, has it happened? You might think so by the growing chorus of accolades being bestowed on high-end class-D amplifiers. In his 2023 The Absolute Sound review of the #Amped #America #AMP2400 #amplifier, #StevenStone praised the amp for offering “an excellent alternative to the #traditional #high-#power #amplifier designs that have predominated for many years” and referred to the view shared by some audiophiles that class-D amps are inherently inferior to class-A or class-AB as being “antiquated”. Hi-Fi ’s #EricNeff in his 2023 #review of a pair of Atma-Sphere Class D monoblocks threw down the gauntlet by exclaiming, “Move over class-A, there is a new flagship in town, and you will want to use it year-round, no air conditioning required”. Stereophile’s Kalman Rubinson, in his 2021 review of #NAD’s C 298, concluded that it, “challenges more expensive amps and should impress discerning listeners regardless of budget”, while in the same year and magazine, #MichaelFremer, in his review of #PS #Audio’s #M1200 #monoblocks, compared the model’s performance to a “Porsche Carrera S” and dubbed it a “miracle performer”. It might be stretching the truth to say that class-D is a recent amp phenomenon considering the #technology was #invented in the ‘#50s and #commercialized in the ‘#60s. Except that it’s only recently that perfectionist audio companies have started using the topology in their higher-end offerings, which have been well-received by the audiophile community. Add in the number of #China-based #companies, such as #Fosi #Audio, #Gustard, and #Topping, that have gained a global reputation for offering excellent-value class-D products and it may begin to seem like we’re in the midst of an audiophile revolution of the likes unseen since the release of the compact disc. What does it all mean for us audio enthusiasts? Just how good is class-D compared to class-AB or the much-revered class-A? Might class-D even, generally-speaking, surpass those more mature amplification classes? #classAB #ClassD #classA/B #Details: ⤵️ https://lnkd.in/gkswE_N3
