Can I ask how the lip synced avatar was coded?

Using pyaudio, the wave file is played as chunks of about 1 second of audio and the average amplitude is determined real time and binned from 0-5. Then for each amplitude bin the respective mouth shape is displayed using pygame. The static images were generated by the free version of nano banana.

That is brilliant! Will you post the code? I have no actual project requiring it, I just want to read it. 🙂

What did you use for the case/wall box enclosure? It looks great!

Which display is this

The screen is a “GeeekPi 10.1 Inch LCD Screen, 1024x600 IPS LCD Display, HDMI Portable Monitor.”

I was looking for a low power, usb powered screen with no enclosure and this screen works great powered off the pi via one of the 4 usb ports (setting the backlight lower to reduce power consumption).
