I noticed this chip is available as a Shield. At first glance it might just be another mp3 file player, but it looks as though it could do a lot more, possibly standalone, as the DSP can have user code installed.
Has anybody used it in an effect?

I have a vs1003 module (which is the similar to vs1053 i think) and going to use it with STM32.  I trying to make a looper with it. I will post when get something interesting.

Cool.
Maybe post something even if it isn't interesting? For the benefit of the knowledge base?
