Amlogic A113L Dual-Core Cortex-A35 Processor Targets Smart Audio and IoT Applications

Amlogic A113L Meson A1

Over two years ago, we reported about Amlogic A111, A112, A113 processors designed for audio applications such as smart speakers. A111 features four Cortex-A5 32-bit core, while A112 and A113D/A113X processors come with four Cortex-A53 cores instead. We have not heard much about those since then, but all those processors are still listed on Amlogic website, A112 is supposedly used in Xiaomi AI smart speaker, and Amlogic A113X1 Far-Field Dev Kit is still listed on Amazon’s list of devkits for Alexa voice service, but currently out of stock. Amlogic has been working on a more cost-efficient processor for smart audio and IoT applications with Amlogic A113L dual-core Cortex-A35 processor shown as Meson A1 in the Linux source code. It was just added in Linux 5.5. We don’t have much information about it, but it’s interesting as it’s the first Cortex-A35 processor from the company, and it targets the same smart audio application as Rockchip RK3308 quad-core Cortex-A35 SoC found in …

Bluetooth LE Audio Supports LC3 Codec, Multi-stream & Broadcast Audio, Nordic Semi Evaluation Kit Unveiled

Bluetooth LE Audio Evaluation Platform

I first heard about Bluetooth LE (Low Energy)- part of Bluetooth 4.0- in 2013 with RFDuino board, and it came to prominence once Android 4.3 added support later this year. Bluetooth LE is using to transmit messages using as little as energy as possible for example to synchronize data between a smartphone and a smartwatch. But if you ever had to transmit audio, you had to rely on Bluetooth Classic which, albeit considering low power, consumes more energy. But you should soon have much longer battery life on your Bluetooth headphone or battery-operated speaker, as the Bluetooth SIG has just announced Bluetooth LE Audio which adds a new codec and support for multi-stream and broadcast audio. The new high-quality, low-power audio codec used in the new Bluetooth standard is called the Low Complexity Communications Codec (LC3). The chart above shows the results of listening tests between LC3 and SBC codecs at different bitrates with a score from 0 to 5 …

Galerdo AI Swimming Tracker Gives Audio Feedback, Plays Music – No Ear Buds Needed (Crowdfunding)

Galerdo Beker Pro Galerdo is a simple to use, swimmers attendant, that holds tight to the head and collects data.  It offers interactive audio, AI advice underwater and even plays music through bone-conduction.  We previously reported on fitness and swimming tracker Makibes F69 IP68 Smartwatch but it lacked audio support. Feature Awards for Galerdo Galerdo won the CES 2020 Innovation Award for Swim Tracker, AI Voice Assistant and Handset Free features. Previous and Present Devices Galerdo Inc has a previous bone-conduction audio device that offered music underwater to swimmers, without the need for a headband or earbuds.  The latest device simply called Galerdo adds AI data collection and spoken advice as the user is swimming, in real-time. Quick Run Down on Bone-Conduction The AI technology that is used in the Galerdo is further enhanced by the bone-conduction transfer of sound and is a technology industry that is growing rapidly. It would not be remiss to mention that sound reception in …
