Can you place another microphone upstream in the sax, if you can it may be possible to use the upstream mic as a switch that turns on the sampling if it get a signal before the ed. you placed.  This is not foolproof but may be any easy method that work well enough.

Why choose a microphone?
Surely you need something more like an anemometer?

A microphone is the wrong sensor to use. You want to use a pressure sensor. You want to blow into a Leakey chamber, then the pressure will represent how hard you blow.

Did not think about using an anemometer or a pressure sensor, I thought about the microphone because it was the first thing that came into my mind. Thank you for the suggestions Sir Grumpy_Mike and Sir AWOL. Thank you also wwbrown You guys have been a lot of help, I'll look into using your suggestions and try them out when we work tomorrow! :)

Will try looking on pressure sensors and anemometer circuits, sorry not that familiar with these two. :)

Yes sir


that's about the best you can get when using a single frequency for one tone.
For a more stereo quality sound what some people are doing is pre-recording the sounds then using a stereo IC and the arduino to mix it.

Hi I made a microphone circuit and I plan to make it detect only the wind blowing for my Saxophone project. So far I am having problems on how to do this because when I blow wind to the microphone it gathers data and when I also talk it also gathers data. How can I let my circuit only gather data wind blowing from the microphone?


You could add a second microphone with a windscreen. Subtract signal that the windscreen'd microphone receives. Just an idea.

Here's an example of a blow pressure sensor: http://www.instructables.com/id/Arduino-Controlled-SIP-PUFF-Switch/

Another thing to add would be a force sensitive resistor where the reed would be. Allow the user to apply pressure with their bottom lip to "bend the tone higher" (damn I played sax for 10 years and don't know the proper term).

It's all good man! We just had finished our Project and it's working out great for us. I just posted the video to let you guys know. and I would like to thank all the people from Arduino.cc for helping me! Thank you for advice though. :)
We used a blow pressure sensure by the way.
I would like to especially thank Grumpy Mike for this! :)
