there should be. I've not looked into it yet. did email the developer though. apologies for not posting sooner!
Looked around and found this one, seems promising, quite sensitive and reproducible. https://play.google.com/store/apps/details?id=com.soundlim.panotuner
Just get Perfect Pitch for your PC - add a £1 microhone off eBay and bang the input gain up as high as it will go.
far too lazy to fire up the PC and then on the headset etc. that pano tune seems OK. tested a known other racquet that had stabilized. also can test on the go.
I updated to the latest version of the Carl Tuner and it does work. Not like before though and not as easy. Now I get a reading on every couple strums but I have to stand the racket vertically next to the phone's microphone, with the head down and just hold the racket cap. I also tried Pano Tuner and that actually worked just like Visor posted. I second Visor's post, skip Carl Tuner and use Pano Tuner. I got same readings on both apps, with Pano Tuner being much easier to use.
Also found another sensitive tuner app, with real time FFT waveform display. Pretty nifty, and it's free. https://play.google.com/store/apps/details?id=com.ntrack.tuner
I was just going to post how well n track works for iPhone. With ClearTune I wasn't getting great readings so I did a quick search and n track came up. My readings fall right where it should be when looking at previous stats. I prefer hitting the palm of my hand or against a hard object and it gets the same reading as if I would strum it so it works quite well here =D let the monitoring begin!
^ Yes, and now that we found several that work well and are quite sensitive, don't forget to set it to never update the app...
Good news re CarlTune, the developers listened to our complaints and the latest most recent update today has restored sensitivity to previous level.
ZM62 mx60 1260hz. manual drop weight and freshly strung so cannot count it, but that frequency is very high for 21/23lbs!
freshly strung zm62 at 23x24 lbs, 1210 Hz after overnight, 1190 Hz after 2 hrs play, 1170 Hz compared to 22x23 lbs, which has now stabilized around 1130 Hz after several weeks of play
@kwun @Mark A @blableblibloblu So, I had some free time yesterday and while explaining stringbed frequency to stringtehcno, I discovered an interesting relationship between 2 different tensions of the same string. From http://en.wikipedia.org/wiki/Vibrating_string , we kmow that there are only 3 variables that affect stringbed frequency : Where: is the tension, is the linear density (that is, the mass per unit length) ie. string thickness is the length of the vibrating part of the string. Therefore: - the shorter the string, the higher the frequency - the higher the tension, the higher the frequency - the lighter (ie thinner) the string, the higher the frequency There's also an interesting relationship between frequency and tension in that formula. If one is comparing the same string at two different tensions, then is constant and can also be considered constant (since the few cms in length difference at various tensions are negligible relative to the total length of string), then we can see that we can relate the two frequencies by f1 / f2 = √(T1/T2) or f1 = f2 x √(T1/T2) Hence, two tensions are also then related by T1 / T2 = (f1 / f2)² or T1 = T2 x (f1 / f2)² So, now we can easily calculate or predict what the tension or frequency is or should be at any given frequency or tension for any particular string.
Ahh - formulas (ae?). It'll be interesting to see how this maps to real life (and we've got to dial in some way to account for "up-time", too).
^ But the interesting thing is that if you know one tension measures a particular frequency, then if you measured a lower frequency a few weeks later, then you can calculate exactly what that lower tension is. So take one of my readings for zm62 for example. 1210 Hz out of the machine at 23x24 lbs, ends up 1130 Hz after 3 wks of playing. That means it has become 20.9 lbs. Or if we allow it to rest and stabilize after stringing, after 1 day with no playing it measured 1180 Hz and take that as 24 lbs, then 1130 Hz after 3 wks of playing becomes 22.0 lbs. Formulas (ae? ) don't lie.
will have to put those formulas to the test! The string stiffness thread is also interesting. I'm still shocked by the stiffness results from that other thread (microlegend being so stiff)
0.70 done a couple of weeks ago ringing at 1100Hz. I know it's a hard string depending on who you ask, if this is even relevant, but I still think this is too high for 24x26 progressive on Victor 80 hole. Old Victor pattern I think. Thoughts? I bought a scale which seems accurate to +/-5g or so to test. Even if that is half a pound out it's a rough guide. My 26lb squash attempt 'felt like 32'
