New web-based Real Time Tuning Analysis tool

[Michael Eskin]

Having my Chromatic Tuner now working nicely, I realized it was a simple and obvious task to leverage the same code base to do this:
 

https://michaeleskin.com/abctools/rtta.html

This tool can be used to check the pitch of an instrument across its entire range, as well as for checking how well you play in tune.

The tool is primarily for instruments that can produce long sustained notes like flute, whistle, Uilleann pipes, concertina, accordion, and fiddle.

It should also work on phones and tablets as well as desktops but it can be a lot of data to show on a small screen.

This tool was inspired by Terry McGee's original Tartini-R Polygraph RTTA tool at:

My simple web-based chromatic tuner is available here:

or can be launched from the bottom of the ☰ menu in my ABC Transcription Tools.

This is terrific-- many thanks, Michael. I have suspected my concertina is "out" on a few notes and it is.
I've also heard, though, that they are sometimes tuned tyhat way to make certain chords sweeter, but it does grate on my ear a bit when I"m playing tunes with others.

I've updated the Chromatic Tuner and Real Time Tuning Analysis (RTTA) tool to now support both Equal Temperament and Just Intonation (with selectable root note).

You can now print the graph or export it to PDF using the browser's print feature.

Best results using Landscape as the print orientation.

Here's how you would do it on iOS:

In mobile Safari, click "Share".

In the sharing pane, scroll down a bit and click "Print"

On the "Options" pane for printing there is another "Share" button that will allow to save a PDF, email it, or transfer it to another iOS app.

I've added the ability to export the RTTA graph as a JPEG image.
 

Click the new download button at the bottom right of the graph to start the export.

On mobile devices, you'll get the best looking results by first rotating your device to Landscape orientation before exporting the image.

If you use the ABC Transcription Tools, the RTTA utility is part of the offline cache, so to pick up the new versions, you'll need to update to the latest version of the tool:

3156_012226_0900

The version number is displayed at the bottom left of the “Settings” dialog in the standard editor.

If your version starts with a number less than 3156, click the version number to do a manual update of the tool then do a hard refresh of the page.

It was easy to add a CSV export button along with the JPEG export.

The raw data looks like this with the note name and median cents offset value for each sampled note:

Note,MedianCents
G4,34.1
D5,-3.0
E5,-0.4
F#5,18.1
G5,7.3
A5,-14.6
B5,10.6
C6,-12.0
D6,8.5
E6,-2.2
F#6,16.8
G6,5.0

You are very talented! I bought the Englitina app and have been loving fiddling around on my breaks at work with it.

 

Thanks for your work!

Michael, 

 

I can see that you have put a lot of work into this application, and I truly envy you your skills, however in the tuning of a concertina I am not sure what benefit can be realised. You cannot just sharpen or flatten an instrument like on a whistle, and I cannot see how the pitch spread information can be used to refine a reeds performance. Have you explored the application of your software to the refinement of concertina reed performance and tone?

This tool is primarily for flute/whistle players, but could be used to characterize the overall tuning of a single reed/note free reed instrument like a concertina or one isolated reed block of an accordion.
 

I won't be doing any other enhancements specifically for concertina reed tone, but if anyone is interested in that sort of thing the source code for the tool is on GitHub, with a link to the repository at the bottom of the instructions (click the ? at the upper left of the tool).

Thanks Michael, I guess that the practical issue is what one has to do to a reed to compress it's harmonics as demonstrated by your software.

[Michael Eskin]

I'm not sure what you're talking about or how it relates to the functionality of the tool.

Like any other tuner, the tool just shows the closest note and pitch offset from the chosen temperament in cents of what it hears.

If some other harmonic dominates when playing a reed, it will could pick that up as the displayed pitch.

Hi Mike 

Having trouble getting it to work.  Checked microphone and it is picking up fine in Mozilla but will not let me unmute for specific app. 

Took photo of page.

Any ideas?

Thanks

Doug  

[Michael Eskin]

No idea why you can't get it to work on your browser, sorry.  Are you seeing any input level in the tool at all on the input level bar on the top right?  Have you tried the various level boost options in the tool?

Works fine for me on Firefox on the Mac.  Not getting any reports of other issues.

Can you try it on Chrome?

Hi Mike,

Works on Chrome just fine!  Weird.

Thanks again

Doug 

[Michael Eskin]

No idea why your system is fighting Firefox. Glad you could get it working on Chrome. 

Did you grant the tool permission to access the microphone when Firefox asked? 

You can check the permissions by clicking the settings on the address bar at the top of the browser tab to the left of the URL entry field.
