Solo-dev here doing a passion project on my free time with the help of 11 pixel artist and my friend doing the intro song.
Thought it would be funny to make a game where you have to find “keys” to open chest. And by “Key” I mean the key of the song playing in the background. And to find it you have to play on a guitar IRL, but tbh it works with any isntrument.
So I used a pitch detector to listen to godot audio input and now the game is realeasing on June 9th.
If anyone would like to try, lemme know I have beta keys.
cheers

Sounds interesting! I’d like to try, but I’m a fairly competent musician, and so not an average tester. I do have quite a variety of gear to test with though

that’s exactly how I have been testing my game
I play rocksmith 2014 a bit so I made sure cable works
and focusrite is great to play multiplier as godot only supports 1 audio input
I can send you a key if you shoot me an email at edy.picture[at]gmail.com

sounds cool, how did you do the pitch analysis? i recently did a project where i made a note matching game which used microphone input and an instrument to play a game, which kind of sounds very similar.
i personally used a mix of techniques but it was not a small amount of work to get the detection working right 
. I would be interested to know if i just overcomplicated things
I used the plugins in the Asset Lib
started with the first one PitchDetector - Godot Asset Library
That was honestly good but had some issues that could have been my fault tbh
Switched to Note Pitch Detector - Godot Asset Library
I have seen it work ok with microphone but nothing beats connecting guitar instrument.
Lemme know if you want a key !

oh okay, might take a look at those, thanks!
Thanks for the offer but i dont actually play the guitar and currently dont even have any instruments at home anymore, so i dont think i would even be able to properly try it out, sorry

I set the input channels in the audio menu, but I couldn’t get any input through. If the grey bars in the lower left corner are input volume, it was flat zero. I afterward checked the inputs in a DAW with no problems.
I also checked the audio interface settings, which showed that it was being used by an application. Not sure what the problem might be?
thanks for flagging, will investigate right now.
