Microphone Comparison & Selection: I compared the INMP441 with alternative I²S MEMS microphones, including the ICS-43434 and SPH0645LM4H-B. I evaluated factors such as I²S compatibility, SNR, frequency response, power consumption, size, and availability. I decided to keep the INMP441 as a provisional candidate while continuing to verify availability before the final purchase. I also updated the PocketPlayer component documentation with the comparison and selection reasoning.
