Project Idea, can it be done?

[Adily]

Hi All,
I have an EV with data on the OBD2 connector. This data can we seen with an app on Android via Bluetooth.
I can see throttle, brake, speed and steering angle along with acceleration (G-force).
I would like to overlay engine sound and found this gem (https://markeasting.github.io/engine/) making the sound I want. Any suggestions how to accomplish this with adafruit products?
Thanks,
Adily

First, ask the person who created that web site if the sound is generated by an algorithm or recorded, and if the method could be adapted to your project.

We do have boards that will generate audio. You could use a Feather with a Music Maker with a list of engine noise tracks on an SD card:

Even if you're just hopping from one track to the other, having three or four options for each state will keep the output from sounding predictable.

If you find a software system to generate the sounds, you'll need to find out how much computing power it needs. Microcontrollers have pretty good computing power, but don't have much memory (at least compared to a full computer). You do have the option to use a small computer like a Raspbery Pi Zero:

but that will change the hardware you need to generate the sound.
