Hi,

I'm using the circuit from:

http://www.pjrc.com/teensy/gui/?info=AudioInputAnalog

With a Teensy LC, what component would I adjust to alter the sensitivity? I'm using this with headphone output from an MP3 player.

I'm also passing through the audio signal to an amp/headphones.

Thanks,
David

None of the Teensy Audio Library works on Teensy-LC yet. Someday a subset of the library will support LC, and some initial work has already started towards that goal... but a *lot* more remains to be done to port to LC's less powerful DMA controller.

Today only Teensy 3.0, 3.1, 3.2 are supported so far.

Hi Paul,

I'm using the LCAnalyzeFFT library (https://github.com/jeff-hamm/LCAnalyzeFFT) which is working ok for my needs (simple beat detection)

However the output data seems quite low unless I max out the volume on the mp3 player.
