Due to limitations of the previous setup it was necessary to go through a huge change in the audio train.

In a nutshell the 3 leds currently show what will be the output to Fredd13's motors as decoded from the audio playing.
Blue = combined stereo volume
Green = left channel only volume
Red = right channel only volume

The boring bit...... Previously there was a separate mp3 module playing the audio, I was then able to read the voltage on the left channel through an ESP8266 in order to sync movement to ONLY the vocal (left) channel.

Now I have started a fresh. Using an ESP32 I am able to decode *.wav files from an SD card before passing the audio out to an I2S DAC Amp. This allows me to take level readings from the combines stereo output, left only, right only, without any of the background noise from reading an analog input.

It may not look like much, but it was a lot of work to achieve, I'm pretty happy with it myself :D and another awesome benefit is that this will bring the physical size of the electronics to less than half what it was previously!

Hopefully in the next update we will see Fredd13 back together & working again after his previous mishap!
