    Thanks for the help. I've toyed around with a few values and using the values suggested I get output, but when I reduce the gain of the sine wave to zero there output drops to zero. I don't want to have a sine wave in...

    Whoops! I added: AudioMemory(8); mixer.gain(0, 1); mixer.gain(1, 1); mixer.gain(2, 1); mixer.gain(3, 1); to the setup line and I seem to be getting some data now. Thanks for the help!

    A good suggestion, I'm hoping to avoid additional hardware, so waiting looks like the best option for the time being. Thanks for your help.

    Hello! I just purchased the 4.0 and I was looking to do some FFT on live audio. I currently have a microphone that produces a 1.25V biased 2V peak to peak signal which I have been using with a MSGEQ7 and Teensy 2.0++. I...
