After clamping the watch onto your mic, let Tg run!

Now understand that I'm a watch n00b, but as I have read, the lift angle is "the time the balance is in contact with the pallet fork." Most watches use 52, but my Seiko in this example uses 53, and the bph setting is 21,600. Next, you'll need the 'lift angle' and beats per hour for your watch. A CMedia USB sound dongle required a +3.6. In my case, the C270 mic need a +2 offset. Then sit back, watch the dialog, wait until the calibration finishes, and you'll see Tg automatically enter the offset value.

Run Tg using the tg-timer command, then click the Calibrate button. Simply clamp your quartz watch with its back to the mic input. More details about this process may be found in this msg. The first step is to calibrate Tg to your sound card. After installation, I checked the mic and its input level:

One additional piece of software I found handy was Pulseaudio's pavucontrol, a gui client interface to sound devices on my Raspbian system. Please note that I am an amateur watch person, so my horological knowledge is quite in the n00b status. You'll also need an inexpensive quartz watch, and input microphone - i use a Logitech C270 webcam for a mic - and of course, your automatic watch. Simply follow the instructions on Tg's page or Marcello's github page and you'll see that Tg builds and installs under Raspbian quite easily. You'll need a few extra software packages and libraries, along with, of course, the normal development tools.

To install tg, the first step is to download and build the software (I don't think Tg is in Debian mainstream - yet!).

NOTE: For a detailed explanation of many of Tg's features, to learn how to interpret the graphical and digital output, and for training on how to use a timegrapher, get this *very* helpful document: This short post will show you my simple setup on how I use Tg with a Raspberry Pi 3. Again, many folks will simply use Tg in order to get their watch to the greatest degree of accuracy (shortest loss/gain of seconds per day).

This program uses sound analysis and 'listens' to your watch, then reports information about how it is running. Maintain your automatic watch's accuracy or to diagnose and determine if I was using those app to get a general feel of the regulation of the rep before, now I've built a better microphone with a piezo sensor (= mic that only listen to vibration and not "sound") and use a professional timegrapher software on a dedicated computer (had to put some audio filers and bypass on the sound card to get a clean signal).Marcello Mamino's Tg timegrapher is a fabulous piece of software you can use to If they don't "hear" correctly the watch, they'll produce erratic results like that. Those types of apps rely on the integrated microphone and have a poor sound algorithm to detect, clean and analyse the signal provided by the watch. Not being good enough at watch tinkering yet, I'm pretty sure you are right, but I'll just say that there's also another factor to take in account here. No movement is even perfect, but there is plenty of room for improvement in this one. If "perfect" all those dots on the bottom graph should be in a nice straight line. If you see such deviation in a single position (and it's not being bumped at all) the movement needs a service at least- possibly low amplitude (which your ap does not indicate) or high end shake of the balance as well.
