You most likely know that your telephone and laptop computer run on chips that energy their core features. What many individuals could not realise, nevertheless, is that the headphones and earbuds they use daily additionally comprise chips.
In some ways, fashionable headphones are starting to resemble miniature computer systems: all the time current, extremely related, and more and more pushed by voice as the first interface, moderately than a display screen behind a metallic slab.
A lot of this tradition audio {hardware} is powered by Qualcomm. The corporate’s know-how is utilized in merchandise resembling the most recent boAt Nirvana Eutopia 2 Professional headphones, which run on the Snapdragon S3 Gen 1 platform, a compact wi-fi audio chip designed for superior sound processing and connectivity.
Qualcomm and boAt are pitching a reimagined audio expertise that’s all the time prepared to take or make high-quality voice calls, hear the most recent information, take heed to podcasts or audiobooks, or immediately stream music, whether or not you might be on the gymnasium or attending a morning working membership.
For audio merchandise resembling headphones, the basics stay unchanged: efficient noise cancellation, immersive sound, and the power to listen to precisely what you need. These options proceed to kind the inspiration on which such units are constructed.
Snapdragon Sound delivers crisper, clearer sound
Nevertheless, Qualcomm’s Dino Bekis says the corporate is targeted on three technological pillars: enhancing high quality, integrating into low-power environments, and adapting to regional and shopper variations.
“We’re all the time interested by find out how to combine pace into the lowest-power setting potential. A number of that comes all the way down to {hardware} offloading, the selection of course of know-how, and structure. What we would like is to allow these experiences whereas delivering the identical or ideally higher battery life, as a result of these units have gotten an increasing number of part of on a regular basis utilization,” Bekis, Senior Vice President and Common Supervisor, Wearable AI, Qualcomm, instructed indianexpress.com in an interview.

The brand new boAt Nirvana Eutopia 2 Professional helps Snapdragon Sound, Qualcomm’s devoted audio know-how that leverages each {hardware} and software program to ship high-quality audio on related units. Snapdragon Sound allows options resembling lossless audio over Bluetooth, head-tracking spatial audio, and Auracast broadcast audio throughout a number of transmitter units.
Whereas sound is extremely subjective, technical measurements can be found, much like how lively noise cancellation (ANC) on headphones is evaluated.
“I feel sound high quality could be measured, so you are able to do the identical factor for echo cancellation on microphones – very foundational, data-driven evaluation and measurements are carried out once you discuss sound high quality. There may be actually a subjective factor there as nicely. However I’ll let you know, I’ve been very shocked as a result of, you recognize, once you speak to professionals, whether or not they’re producers or artists, they’ll instantly hear the distinction between superb sound high quality and not-so-good sound high quality. It’s not even a five-second judgment,” Bekis stated.
“I feel it’s about how true it’s to the supply, the unique supply, and the way nicely it’s really reproduced,” Shyam Vedantam, Chief Product Officer, boAt, chipped in.

“We’ve seen audio constancy and help for bit charges enhance over time, the place Snapdragon Sound, as a platform, has an inherent benefit. It helps really bit-perfect, lossless audio on a Bluetooth gadget, which isn’t very simple to attain,” he added.
Improved ANC efficiency
Bekis stated the technical problem lies in dealing with sudden or loud, intermittent noises with out introducing points like howling or instability within the audio. He provides that ANC efficiency could be evaluated utilizing measurable technical metrics resembling decibels (dB) of noise discount or isolation, which assist quantify how successfully a system suppresses undesirable ambient sound.

Nevertheless, getting ANC efficient in Indian circumstances whereas listening to music has all the time been a problem, stated Vedantam.
“What works in much less noisy circumstances won’t work in very noisy site visitors circumstances like these in India. So how does the platform adapt and work throughout various kinds of ambient noise, whether or not on the highway in site visitors and even at dwelling, the place Indian households have completely different ambient noise profiles? The query is the way it works in real-world circumstances and successfully solves these issues,” he added.

Conserving Indian customers in thoughts
Vedantam stated boAt labored intently with Qualcomm on the boAt Nirvana Eutopia 2 Professional. He not solely cited robust collaboration with Qualcomm but in addition highlighted how the corporate assessments the headphones in real-world circumstances and iteratively fine-tunes merchandise primarily based on person suggestions.
“Whereas there’s a robust basis supplied by the Snapdragon SoC, the appliance layers constructed on high of it are equally necessary. The query is the way you fine-tune and calibrate them to work nicely in real-world circumstances. The {hardware} additionally extends to different elements, resembling microphones, that are essential, in addition to correct driver choice. The acoustic chamber design additionally performs an necessary position in making certain a high-quality audio expertise,” he stated, describing the end-to-end audio design course of.

Vedantam stated calibration and testing occur at a number of phases of the product lifecycle, which begins on the idea stage with prototyping and lab testing, then continues by growth with repeated real-world testing. The corporate additionally conducts intensive alpha and beta testing with customers, together with a devoted group that tries early prototypes and offers ongoing suggestions on real-world efficiency. Lastly, the product is iteratively refined in collaboration with companions till it reaches full maturity and is prepared for launch.
boAT additionally depends on “skilled listening to”, the so-called specialists with extremely delicate listening to who can distinguish between good and nice sound. These specialists additionally perceive regional buyer preferences, permitting them to fine-tune audio efficiency for particular markets. The corporate additionally has inside audio specialists and “golden ears,” and infrequently collaborates with musicians, artists, and professionals from the audio trade.

Rising use of software program and AI
“I’d say you actually want the {hardware} functionality, which actually comes all the way down to being able to offer granularity of tuning – the power to show filters on and off, dynamically regulate them, and have a number of flexibility. So the {hardware} should supply large flexibility. I feel software program and more and more machine studying algorithms are what drive the power for ANC and different audio efficiency options to essentially stand out. With out that software program and people algorithms, the system simply doesn’t actually execute,” Bekis stated.

“After we do testing, an increasing number of of what we do by way of take a look at instances includes leveraging AI to construct these take a look at instances and adapt as we discover new areas we need to optimise for. We use that as a part of how we develop our testing methodology. The second factor we do is that algorithms for ANC, echo cancellation, and microphone noise suppression are more and more shifting towards extra complicated fashions. They run consistently, and the best way you preserve battery life is through the use of devoted {hardware} or embedded NPUs that may run them as effectively as potential.”
Enhancing premium headphone expertise
Despite the fact that wired headphones are making a comeback, this resurgence has not gone unnoticed by customers.
