Need help to select Arduino board


I am planning to start an audio project. I am looking for a board with preferably Cortex M3/M4 micro controller. I prefer on-chip 16 bit ADC/DAC and a way to interface bluetooth transceiver.


The only Official Arduino board with a Cortex M3 is the Due.
However, "Teensy 3.1" has a CM4 and an extensive audio library.
And the TI "Tiva Launchpad" has a CM4 with floating point, and is supported by Energia

Thanks a lot. Let me check up on Teensy.
