Couldn’t resist and upload the FLAC patch to the VS1053b. Tried the lowest bitrate I could find (877kbps) and started playback. Guess what, it played. Not fluently though, SPI transfers went through the roof and DREQ was active 100% of the time, so it wouldn’t respond to anything. But hey it played better than expected!

Hmmmz… AVR ┬árunning @20MHz @5V, add a couple 10+ MHz logic level converters and see what surprise that brings… just sounds a whole lot better after this little experiment :)
