Bluetooth LE Audio offers advances in wireless audio including more robust audio quality and low latency operation while Packetcraft’s Link Robustness Package helps maintain link quality and coexistence with neighboring networks. This particular package was developed to improve the quality and streaming performance of LE Audio applications and includes interference Detection and Avoidance (DAA), dynamic closed loop power control of the transmit PA and receiver LNA, and supports receive-side antenna diversity. Products can use DAA to help comply with European radio regulations while transmitting at higher power.
The Demo Kit showcased at CES 2024 includes two Nordic Semiconductor Thingy:53 IoT prototyping platforms with built-in microphones, a Nordic nRF5340-DK module with Packetcraft Audio Interface Board, and running Packetcraft’s fully compliant and commercially shipping BLE solution with Bluetooth Qualified Host, Controller, LC3 codec, and the wireless multi-microphone sample application.
Packetcraft’s Demo Kit allows for the evaluation of range, performance, and robustness of two simultaneous audio links with latency as low as tens of milliseconds. This platform also supports microsecond-level synchronization between two microphones, which is useful for Ambisonic and spatial audio recording. Original attempts to create Bluetooth-based binaural microphones embedded into earbuds that have struggled with latency, interference, and recorded audio quality, will now benefit from this LE Audio solution.
“We introduced the Wireless Multi-Microphone Demo Kit based on LE Audio because the market for standards-based wireless microphones represents a new major product segment in both consumer and commercial audio markets, especially as accessories for mobile phones,” says John Yi, CEO at Packetcraft.
Multiple manufacturers and partners are demonstrating LE Audio and Auracast products using Packetcraft's comprehensive Bluetooth software solution during CES 2024, including in the Auracast Experience hosted by the Bluetooth SIG.
“Packetcraft is proud that multiple product companies are commercially shipping wireless audio products using our Bluetooth Qualified LE Audio and Auracast-capable broadcast audio software including Host, Controller, LC3 codec, and Link Robustness Package,” John Yi adds. Packetcraft plans to offer the new Wireless Multi-Microphone Demo Kit based on LE Audio in March 2024 and the company is taking pre-orders now on its website.
Packetcraft’s leadership in Bluetooth LE began in 2009 with the founding of Wicentric, continued through Arm’s ownership in 2015, and is maintained today as the company offers new technological innovations such as LE Audio and Auracast broadcast audio, Bluetooth 5.4 PAwR / ESL, and other emerging technologies including Bluetooth Channel Sounding and UWB come to market.
