FFT/DFT Library inquiry for acoustic communications
Good afternoon everyone! I'm currently a student engineer and am inquiring on any DFT library for the mbed LPC1768 to utilize for my project. I'm designing and testing an acoustic modem to send data between receive and transmit circuits on land. I want to use a binary frequency shift keying approach with a simple omnidirectional mic and 8-ohm, 1-watt speaker. I've been searching for a library that can just take in the mic reads (amplified from mV to volts) and perhaps analyze and spit back data (maybe in an array?) so I can plot and see what data it is transmitting. Any resource or supplement would be useful. Thanks a lot!
