Can I make a real-time audio processor with a MAX4466 mic, PAM8403, 2 bone conduction transducers, and an Arduino uno? I know I have to use a low pass filter, but I am a complete beginner and confused about everything.
I'm going to say no. You probably need something with more processing power/speed.
The Uno doesn't have enough processing power for "high quality" audio or much audio processing. Plus there is no built-in DAC, and the ADC is only 10-bits and slow (it can't sample at 44.1kHz).
Do you have any recommendations for a micro processor?
The Arduino compatible Teensy 4.x processors are very fast and have reasonable audio capability. Plenty of info on the PJRC forum and website.
