Grove Speaker to play recording

Hello, I currently got a grove speaker with the intention of playing a recording on it… is it possible to add a recording for the grove speaker?

The way I read the docs of the Grove Speaker is that there is a predefined set of sounds the device can generate and the selection of which it should play back is done via some “magic” PWM frequencies, but I can’t see how you’d upload new sound samples to the device.

Have you got any sources of this being possible at all?

No thats why i am asking, on the grove wiki they give vague description.

Then I’d say: “No” to this
