I'm doing a larger scale project with 1-2k RGB LEDS using the FFT capabilities of the audio library. I'm very much a beginner, and I've seen this question posted before many times but haven't been able to make much of it. I just had a few questions:
Are there any advantages to using the audio line-in I2S on the Audio Board as opposed to wiring a line-in signal as referenced on https://www.pjrc.com/teensy/gui/?info=AudioInputAnalog to an ADC pin on the board? I really only need it for the line-in audio input, but I've read that I would get a better signal using the board over an ADC pin.
If these advantages are significant--ideally, I do want a decent resolution in the 5k+ range--do you know of a way to use the two boards together? I know I'd need to shuffle around some pins in this case, but (again, very much a beginner) I'm afraid I wouldn't know where to look to begin doing that. Any advice you might have would be tremendous.
