    FYI, 'hibernate' sleep should work it just wakes with a reset. I'm not surprised by those numbers, thanks for posting. Currently I'm doing a huge home automation project so I'm not going to look at Low Power stuff...

    No I haven't looked into that at all. I tried to make sure all the examples worked :) One caveat is that hibernate wakes through a reset currently.

    Did you try to download the latest Snooze beta for T4 support? Just clone it or download the zip file I haven't updated the releases since I want to get any bugs squashed first.

    A couple of things that stand out is that you do not need the Timer driver just the Alarm driver. In the included sketch I also use the USBSerial driver to aid with printing to the Arduino Serial Monitor. You have to...

    This is exactly why I refactored my Snooze library into different HALs for the different Teensies even if 90% of the code base is the same. It was getting to the point that I couldn't follow my own code anymore before...

    Do you do any filtering before feeding it to notFreq? That could help if the mic is picking up a lot of outside or internal noise. Also I found in my guitar tuning application I got better results if I low passed the...

    Oh cool, I just pushed an update to Snooze for T4.0 support. I guess I'll have to add T4.1 support now too:) I'm considering T4 support beta now but it seems to work for me, haven't looked at any current measurements...

    Not sure what you mean, so the latency is good but when the player is double timing it the algorithm can't keep up? Have you tried adjusting the threshold value? A smaller value will make the algorithm more precise and...

    What teensy are you using? What is the lowest frequency you are expecting to measure? How many AUDIO_GUITARTUNER_BLOCKS do you use?
