There are a bunch of tuner add-ones for audacity. Everything is open source. Should have plenty of stuff to dig into there to get you what you need.

Something like this should be promising for you, too: https://www.nongnu.org/lingot/

As far as what the OP wants to do, I'm confused. Any tuner that passes through the signal will do what is being requested. I think there must be some other factor that I'm not following. It sounds like what is being asked for is a tuner that outputs a "pitch corrected" note, but that's not how tuners work.

I want to be able to send the signal indicating the frequency from the tuner's output to an input that can receive that "value", interpret it and act on it. The tuner can be a physical tuner that sends output to an app, or a software-based tuner /app using mic'ed input.

It looks like the output from the Korg is just the passed-thru analog instrument signal. What I am looking for is a way to receive the same output from the tuner that is instructing the tuner to display "A" when the input frequency is sensed at ~440hz.

I hadn't thought of Audacity, thanks!

Could be something to work with, if it is portable off of LINUX. Thanks for the heads up

They don't work well on electrics, and I can't tune with it in the middle of the song, in the middle of a band, in the middle of the stage.

PS -painful to use when I'm not wearing shoes…

Probably not what you need BUT my “frozen ape” “Pitch” on an iPad is wonderful. It allows a color coded visual and, to the tenth, frequency, which allows me to balance tune my imperfect acoustic instrument to the most pleasant sound that the instrument can produce. And i can watch my strobe clip on peterson for corroboration if i want.

Does it need to be a stand-alone solution? If you can use a computer with an interface and a mic, could you write a VST plugin for a DAW (Reaper can be demo'ed/used free) to do what you want? Obviously you can get pitch information, since there are tuner and pitch-correction VSTs. I've never written one, so I'm not sure if you can do whatever it is you want to do inside a VST, or if a VST can then connect to an app if need be.

I'm having flashbacks. My dad made me use a pitch pipe when first starting instead of letting me have an electronic tuner. It worked out well, but I use electronic tuners now

I haven't used this, so can't comment on how good it is but after searching for "guitar tuner app source code" the first result was to this -> https://github.com/chRyNaN/Android-Guitar-Tuner

Since the source is in github you should be able to modify it to take whatever the frequency is and pass it on to whatever thing you want to use it.

There's also the likes of this -> https://www.codeproject.com/Articles...T-Guitar-Tuner It seems to be Windows based so maybe more accesible for development.

Thanks, At first my thinking was to use a physical tuner, but the more I think and see, a software solution may be the way to go

I can't imagine anyone producing a tuner that has some kind of digital output showing what frequency is being measured. It would be an incredibly niche product.

As long as you have a way to get the source signal into the algorithm then a software solution is the way to go. It'll mean more work in capturing and processing the signal, but both Windows and Android make it relatively easy to get the signal and there are various FFT libraries around that will give you the dominant frequencies for an audio sample. So the heavy lifting is already pretty much done.

I don't have a suggestion for how to make this work but I'm just curious what you want to do with that data. Do you want to have some sort of effects automatically enabled/disabled based on changing tuning?

He's looking for something that will pass the data (not a readout of the note) to another program or app so that the other program can use it in some way for something else.
