How do you get the note from real-time instrument string sound?

A question.. I am making a guitar tuner. When I launch the app, the sound recognition starts using a SoundRecorder.

blocks

Next, I have added a label in screen1. I can change the colors if it is the correct note or not. But, I am stuck in the part to recognize the string note when the string produces a sound.

For instance if I press the 6th string, it will show the note as E, but if the 6th string produces an unusual sound, the note will change to D# or Eb (or any other note). Is this possible? This should apply to all the other strings as well. I am creating this app for myself only.

Might be something here that helps?

I don't want to generate the tone, but rather get the note of the tone from the mic using a soundRecorder.

There is something called a SoundSensor in AppyBuilder that was long abandoned long ago. Maybe an extension developer may want to revisit this.

This doesn't include a note detector as I suspect. I failed to find one. Good recommendation though! Some of those features I can use in my app also.

Of course it doesn't. But we may work out the frequency of the sounds, then get the note from the frequency.

#7

Nice approach. But I can't understand how to work with this. Can you please demonstrate this via diagram? Since this component was abandoned long ago.

I don't think this will succeed - especially since this also depends on the instrument (guitar, bass, ukulele, violin, ...) and the pitch etc. that produces the sound (note).
But good luck. :wink:

I need an example of how to work out this. Please help.

Only guitar, not learning bass, violin or ukulele, so no bass, ukulele or violin

#11

It hasn't been achieved yet currently, as I am working on other assignments as well. But you can try that out yourself and find other methods as well.

I'm curious... but pretty sure it won't be successful. Anyway - as I said - "good luck".
I'm a musician and would love something like this... :wink:

But what about Guitar notes? Pianos and guitar sounds have different style of soundings.

#16

But it is Python, and not Java.

#17

You will be returning the frequency of the sound (if you get it working)

A middle C on a piano is the same frequency as a middle C on a guitar

I have very little idea about frequencies and all those things.. Please tell me how do you get the frequency? I apologize If I have asked many questions multiple times. Please guide me. :disappointed:

Any extension required, or we could do this via built-in blocks?

You would need to create an extension
