My goal is to measure the frequency of an audio signal using a microcontroller. The source of the audio is unamplified (not enough for headphones), with a 100mv amplitude. This isn't enough for my PIC to distinguish between high or low, so I used a MCP6541 comparator to bring it to logic levels.
It works (great!), but I was wondering if my solution is "correct", as in if there is anything I could do to make it more robust, or if there is any glaring problem in my circuit.

I just feel like this is too simple and that I am missing something
