WisBlock Core Comparisons for Audio
WisBlock Audio supports a number of the WisBlock Cores. The table outlines a general comparison between the supported cores.
| WisBlock Core | Core Features | Basic Support | SD Card Recording (RAK18003) | SD Card Playback (RAK18003) | Edge Impulse (Sound Recognition) | Cyberon License (Voice Recognition) | Power Consumption |
|---|---|---|---|---|---|---|---|
| RAK4631 Nordic nRF52840 | LoRaWAN (SX1262) BLE | Yes | Yes | Yes | Yes | Yes | Middle |
| RAK11200 Espressif ESP32 | Wi-Fi | Yes | Yes | Yes | Yes | Yes | Highest |
| RAK11310 Raspberry Pi RP2040 | LoRaWAN (SX1262) | Yes | No | No | Yes | No | Lowest |
| RAK3372 STM32WLE5CC | LoRaWAN (STM32WLE5) | No | No | No | No | No | - |
Core Comparison
RAKwireless WisBlock Audio currently provides examples for two audio processing methods: Edge Impulse and Cyberon voice processing software. Edge Impulse allows you to create your own model to recognize any sound, whereas the Cyberon software only works with voice. Both require a model to be created in order for them to work. RAKwireless provides the model for the Cyberon voice processing software, but for the Edge Impulse, you will need to train the model and record all the training sounds (the more, the better).
For further details, see the tables on the following sections.

Cyberon Model
The Cyberon Model is provided by RAKwireless and users cannot create their own models. If you are able to use the provided model, it is the easiest and fastest to implement. The Cyberon Model trigger and command list is provided in the table below. Refer to the samples for further information. If the RAKwireless provided model does not meet your requirements, RAKwireless can create new models for a fee for larger customers.
