Tuner with an open interface?

[Ds114]

Any common tuner regardless of format (standalone, clip on, inline) displays the note or frequency it is detecting from an instrument.

Is there any tuner that can pass that root frequency signal through to another device/software? That receiver would interpret and process the signal and (as a simple proof of concept for example) display the note on the screen just as the tuner does.

Alternatively, in a solution without a physical tuner, is there any tuner/audio pc software or phone app that has an open interface that can be integrated with other software to get the frequency from it?

Got some ideas I want to play with

How on earth did I manage back in 1961 with nothing but a tuning-fork?

I still have mine! It still works! Battery life is infinite! It works in bright sunlight and total darkness! What's not to like?

I don’t think you’re looking for a tuner - try looking for a frequency analyzer, or audio analyzer, or audio spectrum app. But how and what they pass on, or how you’d access it, is beyond me -

I used a pitch pipe tuner for many years. I considered tuning forks too esoteric.

[EZYPIKINS]

When starting out in my band some 45 years ago.

9 pc band, 3 guitars, bass, Rhodes, B-3, horns, drums, percussion.

All the guitars had their own pitch pipe.

When tuned up everybody hit an A chord. And it sounded like a train wreck.

Got our first Peterson strobe around 78-79.

Difference was day and night. No more train wrecks.

Peterson has been the only choice ever since.

My first thought is to do it with an Arduino. For example, here's an Arduino based tuner. I'm sure there are other examples. If you've not used an Arduino before, its easy to learn, and the parts are usually quite inexpensive.

Or you might look at Free DSP.

Doesn't work in noisy situations. Accuracy depends on the user's ear. Not a fixed method for each string so really only doing relative tuning. That's a few right there.

Once clip on tuners came out the tuning fork went to the museum of antiquity where it belongs. Also my12 string guitar now gets perfectly tuned in a minute or 2. Not so with the fork.

Thank you. I am a web developer and aware of Arduino but never got hands on with it. So it should not be too hard to ramp up. I will dig into this.

Agreed. I said I still have it, not that I actually use it!

BTW, in case you couldn't tell, I was being a bit facetious.

I don't see why you couldn't do this with any tuner pedal. I have a Korg tuner pedal that I also use as a mute when switching instruments. Of course it only works with an instrument with an output jack and pickup.

In case you should ever feel the need to, Peterson sells a clip-on transducer with a cable and 1/4" jack that's designed to work with a tuner for acoustic instruments. I have one and it works fine, clipping on the headstock to pick up the note exactly like any other clip-on tuner not using a microphone element.

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.

If you're looking for a tuner that will output the frequency of the note shown on the display then you can use something as simple as a $20 Korg CA-50 tuner.

How do you clip that on a headstock??

I just used to buy a new guitar every now and then. Easier.
