Assuming you are looking for a launchpad environment, and with the caveat that I am not doing an in-depth analysis of this, my thought is that the MSP430F5529 Launchpad or EVM board would be the least-risk approach. This part is capable of doing flash file system with an SD card and has an ADC12 that you can use to digitize the audio signal. CPU speed up to 25 MHz and USB capability as well.
