This is a community for those who come up with creative ways to make maple syrup. You don't have to be designing and building homemade vacuum or RO systems to participate. Have you done something cool with your buckets and spiles? Tell us! Are you proud of your tubes and buckets? Show us! Have you built your own homemade gravity of pumped vacuum system? Show it off! Do you design, build, or install giant, gleaming, stainless steel maple syrup production systems? Tell us all about it! If you don't make maple syrup but love it on your pancakes of johnnycake and want to ask question, ask away. The people posting here love to talk about making and eating maple syrup.

My father's in his mid 70s and his hearing isn't very good in the frequency range that would be useful for finding his vacuum leaks.

I was thinking about setting him up with a directional microphone and a pitch-shifter app to bring environmental sounds down a couple octaves so he can hear them. There are tons of Android/iPhone apps that will pitch-shift in post, but none of the trial/freemium ones seem to work on a realtime monitor stream, especially on an external USB (UAC) microphone. I don't want to start buying dozens of apps just to try them.

Any app suggestions or other ideas for him?

Great idea. Will try that on the next flow day.
