Designing Audio Products with Qualcomm Bluetooth SOCs and Snapdragon Processors

Qualcomm Design Partner

Qualcomm Logo

As an end-to-end product design firm and Qualcomm Advantage Network member, Cardinal Peak develops audio products for clients that integrate Qualcomm parts for both consumer and automotive markets. Our robust engineering team has extensive experience with Qualcomm’s entire audio line.

Today’s audio space continues to expand the ways that end users can access audio content, from active noise control (ANC) headphones and truly wireless earbuds to smart speakers and full-featured automotive audio experiences. While form factors are proliferating, we see commonalities in our customer’s needs, such as wireless operation, wireless synchronization, the addition of voice assistants, noise cancellation and customized tuning capability. We have successfully supported dozens of A/V product designs with a wide variety of differentiating end-user features.

Qualcomm Audio Product Design Experience

While Qualcomm components can help your brand create differentiated products in terms of performance, features and cost, if you are not a tier-one audio company, Qualcomm provides minimal design support. As a Qualcomm design partner and Advantage Network member, we fill the gap by providing the deep expertise necessary to get your product to market. We have helped many clients integrate Qualcomm Bluetooth audio and Snapdragon parts into their unique products. Recent projects include:

  • Qualcomm CSR8675 SoC, Low Power Audio Headset Chipset: Helping a lifestyle product client develop its Bluetooth headphones utilizing new immersive experience-enhancing technology and working with its manufacturing partner to ensure successful shipping of the product.
  • Qualcomm Audio SoCs CSR8670 CSR8675, QCC5120, QCC5121, QCC5127: Supporting a large audio client with building its entire product line in both consumer and pro audio spaces across three generations of Qualcomm Bluetooth chips, including integration with external components and leading-edge new applications and form factors.
  • Qualcomm QCC5126 SoC, Low Power Bluetooth Audio: Assisting a large audio company with using the digital signal processing (DSP) capabilities in Qualcomm parts.
  • Qualcomm SoCs QCC3020, QCC3046, QCC5125, QCC5127, QCC5041: Working with multiple startups to integrate state-of-the-art neural net and DSP capabilities with Qualcomm technologies and products.
  • qualcomm-snapdragon-sound-logoQualcomm Snapdragon 602A Automotive Platform and Snapdragon SA8155: Configured, built and established the development environment for the SA8155 SoC to include the QNX Hypervisor software and the AMS Audio Framework to be able to execute audio processing features on the mDSP Hexagon core. Implemented, integrated, profiled and optimized audio processing algorithms on the mDSP and demonstrated performance goals, which included utilizing the AMS audio framework, CAPIv2 modules and multithreading.

We develop many automotive and consumer audio products. Additionally, as an Alexa Voice Services design partner, we have deep skills in adding voice to products, plus our deep audio experience helps us implement noise- and echo-cancellation algorithms to further enhance your product.

FAQs About Bluetooth Audio Product Design

What is Bluetooth dual-mode?

The two modes of Bluetooth include Bluetooth Classic, with its BR/EDR (basic rate/enhanced data rate), and Bluetooth LE (Low Energy). A dual-mode Bluetooth radio supports both types of Bluetooth, and most smartphones now have dual-mode Bluetooth chipsets.

What is Bluetooth Low Energy or Bluetooth LE?

Bluetooth LE’s hallmark feature is lower energy consumption. This made it the ideal choice for battery-powered IoT devices. Bluetooth LE also affords more flexibility than Bluetooth Classic. Bluetooth LE supports a range of communication topologies, including: 1) point-to-point, 2) broadcast and 3) mesh. Bluetooth LE can be used as a device positioning technology for high-accuracy indoor location services and direction finding.

What is LE Audio?

LE Audio is Bluetooth Low Energy Audio. The “Low Energy” moniker is the hallmark feature of LE Audio. For comparable audio quality, LE Audio will consume around half the energy. Using comparable power, LE Audio can provide much higher audio fidelity.
