Hello, I am new to the world of Arduino, and for now this project is entirely in the imaginary phase, but I would like to create a device that reads in MP3 files (probably from an MP3 Player Shield, http://www.sparkfun.com/products/10628), and can take that file frame by frame as it's streaming, and analyze the decibel values of the various frequencies, so I could have one individual visualizer for the bass, another for treble, etc. I have no idea how to do this. Any ideas?
The VS#### is what is used on the rMP3 with also up to 23 freqs of analysis.
The rmp3, is good if someone wants a mp3 player shield with a minimum of fuss, where all the code for file reading and spi interfacing to the VS1053 is written and insulated in a high level code.
