Hi all 
I've been working on a massive project for quite some time. Part of it is a voice synthesis system. It uses the vs1053b MP3 decoder.
Please see demo here:
At the moment, I have a teensy 3.2 pulling the files off the SD card and playing sequentially via instruction from the primary CPU (Teensy 3.6).
In the long run, what would my options be for a final product? would I be able to have those MP3 files stored on some kind of flash chip or SMD storage of some kind vs removable SD card? I need the read speeds to remain fast because of the way the audio files are 'strung together'.
Thanks for any advice
Cheers
Andy
