How to use in raspberry pi zero 2w

[Ultimate-raio01]

I do have idea where I want to make an audio communication device using low powered transceiver, so i want to ask like how to use lyra v2 in raspberry Pi zero 2w with tensorflow stuff?????
I want to encode mic audio and sent it to other raspberry pi zero 2 and it will decode the audio in real time.

Help!!!!!!
No one is talking about this stuff

@Tfjjjastro fyi there is a discussion in M17 about implementing the codec as a higher quality alternative to the current Codec2, however the discussion seems stalled waiting for Lyra v2 codebase to became more microcontroller friendly

for the DEVs in this repo, if you can give some information on the microcontroller subject, please 🙏

Hi, did you manage to use it in your Raspberry Pi ?

Hi, did you manage to use it in your Raspberry Pi ?

I am having the same issue here. I don't think it will work since there is no Bazel for Arm.

You're wrong, there is bazelisk for arm

I successfully compiled Lyra for ARMBian in a cheap arm $20 tv box (X88 PRO 10, Rockchip 3318 based, a lot better and cheaper than overrated and overpriced raspberry pi).

And it runs fast enough to allow real time encoding and decoding.

What communication transceiver are you planning to use?

EByte LoRa E22 USB devices ($10 in aliexpress) are fast enough to transmit lyra real time voice, and they have a simple interface, using a serial port over USB.

ID 1a86:7523 QinHeng Electronics CH340 serial converter

More than 500 meters of coverage easily with a tiny antenna and low power consumption in a city building crowded environment. For 433 MHz and 868 MHz ISM bands.

Besides it's tiny enough to be attached to a smartphone with a USB OTG in U-shape. And it's easy to implement in Android through https://github.com/mik3y/usb-serial-for-android

The only problem would be duty cycle of some ISM bands in some countries, that it wouldn't allow legally to transmit real time voice, but anyway it could be used to transmit voice messages.

I uploaded compiled binaries here https://github.com/fdd4s/lyra_speech_codec_test_scripts
to test lyra easily over Linux amd64, linux ARM (aarch64), and Android (sdk 29)
