C5535 DSP SW stores recorded MP3 file under a folder with name RecDir and names them like REC000.MP3. If your project does not has any specific requirements for file location and name, you can do it just by changing the MSP430 code.
You need to understand the control SW on MSP430 for touchpad and virtual register commands to communicate with C5535 DSP SW. MSP430 SW is developed in a modular way so it is easy to understand and modify. If you just need two controls play and record, you can do it easily.
