Bose launches AR audio platform at South Southwest (SXSW), which will allow users to hear sound with glasses

The world's first audio-based augmented reality (AR) platform is set to revolutionize how we experience sound through wearable technology. Instead of relying on visual overlays, Boseâ€™s new AR platform allows users to hear sounds through their glasses, making the experience more natural and immersive.

At the South by Southwest (SXSW) conference, Bose unveiled its groundbreaking Augmented Reality audio platform, marking a significant shift in how we interact with digital information. Unlike traditional AR systems that add visual elements to the real world, Bose AR focuses on delivering sound based on where the user is looking, without altering their visual perception. This means users can still see the world as it is, while receiving additional auditory cues and information.

According to Bose, the goal is to make everyday experiences betterâ€”more meaningful, productive, and enjoyable. John Gordon, Vice President of Consumer Electronics at Bose, said, â€œBose AR represents a new kind of augmented reality that works for everyone. It places audio around you, not digital images, so you can focus on the magical world around you, not a small screen.â€

Bose AR also introduces a compact audio device designed specifically for the platform, optimized for future mobile use. With impressive power and clarity, it can be seamlessly integrated into headphones, glasses, helmets, and other wearables without compromising existing features. Users can control content using head gestures, voice commands, or a tap on the deviceâ€”eliminating the need to touch a screen or type.

In addition to the audio platform, Bose showcased prototype glasses equipped with Bluetooth and microphones, embedding AR speakers in each arm. These glasses look and feel like regular eyewear but offer an audio experience similar to Bose headphones. Potential applications include learning, travel, and even art appreciation, where users can hear background stories about a painting simply by looking at it.

Bose aims to bring this innovative technology to more people, enhancing daily life in meaningful ways. The company is collaborating with developers, manufacturers, and research institutions such as MIT Media Lab and NYU Future Reality Lab to expand the platformâ€™s capabilities. Partnerships with brands like ASICS, Strava, TripAdvisor, TuneIn, and Yelp are helping to create new and exciting AR experiences.

Developers interested in exploring the Bose AR platform can visit the official Bose Developer site to learn more and access the Bose AR SDK. With its unique approach to audio-based AR, Bose is paving the way for a more intuitive and immersive digital experienceâ€”one that listens, adapts, and enhances the world around us.

Power Amplifiers

A power amplifier (PA) is a critical audio component designed to take weak audio signals from pre-amplifiers, mixers, or source devices and boost them to levels capable of driving speakers, delivering loud, clear, and dynamic sound. As the final stage in an audio chain, power amplifiers are essential in everything from home stereos to massive concert systems, balancing raw power with precision to ensure audio integrity.

Class AB Amplifiers

Operation: Combines Class A and B, with transistors conducting slightly more than 180Â° to reduce crossover distortion.
Efficiency:Â GoodÂ (60â€“70%), balancing sound quality and power consumption.
Sound Quality: Low distortion (<0.05%), widely used in home theaters and hi-fi systems.
Applications: Home audio systems, studio monitors, and mid-range PA systems.

Class D Amplifiers

Operation: Uses Pulse Width Modulation (PWM) to switch transistors fully on/off.
Efficiency:Â HighÂ (80â€“95%), generating minimal heat and requiring smaller heatsinks.
Sound Quality: Modern designs achieve <0.1% distortion, comparable to Class AB.
Advantages: Lightweight, compact, and energy-efficient.
Applications: Car audio, portable speakers, subwoofers, and large-scale PA systems.Â

Applications Across Industries

1. Home Audio

ï‚·Use Cases: Powering bookshelf speakers, floor-standing speakers, or subwoofers in 2.1/5.1 systems.

ï‚·Example: A 2-channel Class AB amp (100W x2) paired with a CD player and stereo speakers for music playback.

2. Professional Audio

ï‚·Live Events:

ï‚·Large-scale concerts use multi-channel Class D amps (e.g., 4x1000W) to drive line array speakers.

ï‚·Features like bridge mode (combining channels for mono subwoofer power) are critical.

ï‚·Installed Systems:

ï‚·Commercial spaces (hotels, schools) use 70V line amps for distributed audio, ensuring consistent volume across zones.

3. Automotive Audio

ï‚·High-Power Setups: Class D amps (e.g., 2000W mono for subwoofers) deliver deep bass from car batteries (12V systems).

ï‚·Space-Saving Design: Compact Class D modules fit under seats or in trunks without excessive heat.

4. Studio Monitoring

ï‚·Precision Amplification: Class AB amps with low THD (<0.01%) ensure accurate sound for mixing and mastering.

Nearfield Monitors: Dedicated amps for small speakers placed close to the listener in recording studios.Â

A power amplifier is the backbone of any audio system, translating electrical signals into the sound that entertains, informs, and moves audiences. Whether delivering subtle nuances in a jazz recording or the thunderous bass of a rock concert, its ability to balance power, efficiency, and precision makes it indispensable in the world of audio engineering.Â
