Pico-ITX i.MX8M Board Enables Offline Voice Control with Snips

A few days ago, we covered Estone Technology’s MJ-100 RK3399 rugged tablet. I’ve just realized Estone Technology used to promote their embedded product under the Habey USA brand, which we covered a few times here, and the company has also announced another new product ahead of Embedded World 2019 with their EMB-2238 Pico-ITX i.MX8M board specifically designed for voice control applications. The company setup two voice control demos with the board: one with Amazon Alexa Voice Service (AVS) and another with Snips that works locally without any Internet connection. We actually came across Snips previously for an article comparing microphone arrays, but I never looked into Snips into details or saw an actual demo. Let’s have a quick look at EMB-2238 board specifications first: SoC – NXP i.MX 8MQuad with 4x Arm Cortex-A53 cores @ 1.5GHz, 1x Arm Cortex-M4 realtime-core @ 266MHz, Vivante GC7000L/GC7000LVX with support for OpenGL/ES 3.1, OpenGL […]

Kodi 18 “Leia” Released Ahead of FOSDEM 2019

As one should have expected based on the abstract of the upcoming Kodi presentation at FOSDEM 2019, Kodi 18 “Leia” has just been released a few days before the 2-day open source developer event. It’s been nearly two years since the release of Kodi 17 “Krypton”, and it took a little longer than initially expected for Kodi 18 to become stable enough for an official since there have been so many changes including half a million lines of code added by 36 open source developers, close to 10,000 commits for almost 9,000 changed files. Some of the improvements in Kodi 18 include: Retroplayer gaming with support for gaming emulators, ROMs and game controls. Digital Rights Management (DRM) decryption support to play subscription content Improved Music Library with better filtering, faster API access, and more Live TV improvements including support for new back-ends like Zattoo, Teleboy, and Sledovanitv.cz, as well as enhanced […]

96Boards HiChips Parrot Board and 3-Mic Array Work with Amazon Alexa

96boards Parrot Board Amazon-AVS 3-Mic far field board

Early last year, Banana Pi unveiled Allwinner SoC-Only 3-Mic Far-Field Development Kit for Amazon AVS, a board powered by Allwinner R18 processor extended with an external 3-mic array board, officially supported by Amazon Alexa Voice Service (AVS), and sold for $129 plus shipping. There’s now a compatible board following 96Boards CE Extended form factor, and selling for just $79.99 plus shipping on Alibaba or 555.99 CNY on 1688.com. The board looks almost the same as the original 3-Mic far-field development kit, apart from the LS and HS connectors found in the 96Boards hardware platforms. Hichips Parrot board should not be confused with Allwinner R16 based Parrot board that was used by Allwinner internally, and never made available to the general public. Hichips Parrot board specifications: SoC – Allwinner R18 quad-core Cortex-A53 processor @ 1.15GHz with Mali400MP2 GPU System Memory – 1GB DDR3 Storage – 8GB eMMC flash, micro SD card […]

NXP Immersiv3D Enables DSP-Free Dolby Atmos & DTS:X Audio Systems

High-fidelity audio systems such as soundbars, smart speakers, and AV receivers have traditionally relied on DSPs (Digital Signal Processors) to deliver low-latency audio processing, and enable audio and video synchronization. DSPs add to the cost of the overall design however, and with Immersiv3D technology, NXP has leveraged Arm Cortex-A53 and M4 cores in their NXP i.MX 8M Mini processor to completely remove the need for DSP in audio systems, shaving the BoM cost by up to 20% according to an article on EETimes. Immersiv3D also enables immersive audio support with Dolby Atmos and DTS:X, advanced audio pre/post processing, advanced features like voice control for the smart home. Immersiv3D audio solution was designed to help OEMs to bring to market affordable consumer audio devices with Dolby Atmos and DTS:X, and beside the audio processing software, NXP is also offering an Immersiv3D audio reference design to help them delelop sound bars based […]

This Amplifier Board Features Beken BK3266 Bluetooth 5.0 Audio SoC

I’ve been writing about a few Bluetooth 5.0 solutions this year, but in most case those were based on Nordic Semi nRF52 chips which do support BT 5.0 Low Energy, but not Bluetooth classic which means they are suitable for HID devices, but not for all applications such as potentially some Bluetooth audio application. I’ve just come across a $10.59 audio amplifier board on IC station that is supposed to support Bluetooth 5.0 via Beken BK3266 Bluetooth audio chip. Specifications and features listed for the board: Bluetooth 5.0 Connectivity Up to 6 paired devices Bluetooth protocols – HFPV1.7, A2DPV1.2, AVRCPV1.5, AVCTPV1.2, AVDTPV1.2 Range up to 10 meters Transmission Power – Class2, 4dbm Sensitivity – -81dBm < 0.1% BER Frequency Range – 2.402GHz – 2.480GHz Audio MP3/WMA/WAV music format Speaker Impedance – 4 to 8 Ohm Output Power – 2x15W at 16V/4A, 2x10W at 12V/4A Audio signal to noise ratio >75dB […]
