Some folks like to use a small mallet, sort of like a piano hammer but with a piece of rubber on the end

WRT a hammer or mallet, the thread linked below has a couple of photos of, and brief discussion about an example of one used for this purpose.

hai CharlieT, thank's alot..
may I know what is that tool machine like tuner on the photo?

Henry,

That is an iPhone (or iPod Touch?) running an "app" called "ProTune".

Edit: It looks like the name was changed to "TuneUp"

Still don't know what to do with the carving, shaving, etc.

It is neither of those things, speaking very specifically. If you read his posts, the 'mallet' is a piece of rubber sanding belt cleaner CA'd to a piece of maple, and the Tuner is an iPhone/iPod Touch app called "TuneUp" (formerly ProTune).

Download the free visual analyser software and tap into your PC mic. You'll get better information as it will show you all the resonant peaks, not just the main top frequency. In fact, when you tuner has trouble working out which frequency the top is it is because it is picking up the main air and/or other peaks.
Cheers

thank's Dom, again have you the web address for free download visual analyser software?

Don´t know what Dominic is using, but here´s a free spectrum visualiser: http://www.sillanumsoft.org/download.htm

If you have a VST-compatible host, these two are verygood (and free):

IHA Spectrum analyser: http://www.hoertechnik-audiologie.de/we ... ftware.php

cheers,
Miguel.

Yep the first one, its called Visual Analyser. 2009 seems less buggy than the latest ones. VA seems the easiest to set up and use.
Check out the threads on the ANZLF here http://www.anzlf.com/viewforum.php?f=33 for tips how to setup and use it. Its amazing what you can do with it.
Cheers

I have tried quite a few programs with the capacity to create a FFT frequency graph and I find the Audacity program great and easy to use. That said they all require a bit of experimentation to get comfortable with their features. As for what to actually do with them is a very complex topic. The nice thing with Audacity is I can save the project file and revisit in the future to compare what I am doing to what I have done in the past. Keep records of all parts of the tuning process, and attempt to repeat the results of the instruments that you like the sounds of.

I have a piano hammer that I pot a longer handle on that give a repeatable result.

Hey Fred, I've not used audacity so I am not sure what it can do but the nice thing about VA is that you can collect data from any number of taps and the program will give you the average value of those taps. So it controls a bit for different tapping techniques etc which is good if you are going to start adjusting anything. Most of us set up to take an average of around 10 taps and then save the spectral data into excel.
Cheers

They work the same except Auadacity being a recording program allows better keeping of records, I got the same numbers with all of the programs I used, but settled on using the Audacity.

Thanks fred, I'll give it a try.
Cheers

Audacity is also VST-compatible, so you can always beef-it-up if you need to. VA also looks very nice, thanks for the ANZLF link Dom!

Here's an updated quick-start for Audacity 1.3.13:
- Install as usual: http://audacity.sourceforge.net
- In Audacity: Edit > Preferences > Devices > Recording > Select your mic > OK.
- Record the taps
- Select the tap(s) signal with the mouse
- Analyze > Plot Spectrum
-- Size: Change to "16384"
-- Axis: Change to "Log Frequency"
-- Drag the right window edge to make it ~full screen width
-- Hover the cursor near the peaks... Audacity will automatically lock onto the peak frequencies! Numbers are in the lower left. I've found it's within 1 Hz of Wavesurfer for the air, top, and back modes.

1.3.13 is a Beta but is working great for me in both Win7 and XP.

My tap-test results and procedure are in this thread... viewtopic.php?f=10101&t=31330

Thank's David, I've downloaded Audacity 1.3.13 and I'll try it...
but can the audacity record the tap of plain soundboard, back, side... I read the book of Roger H Siminoff "The Art Of Tap Tuning" he started form plain wood then make some carved or change stiffnes to find the right frequencies or tone...

Audacity can record and analyze any sound, but for methods and theory, I'd recommend other resources over that book. See the archives for posts by Alan Carruth -- e.g.:

And see these articles: http://www.pantheonguitars.com/DanaBour ... ticles.htm
And the books by Gore & Gilet, and Somogyi.

FWIW, Roger Siminoff sells a nicely made tap tuning hammer.
