Measurement of the resonance curve (Acoustics)
Little update:
I just submitted a beta version for the next phyphox update 1.1.6 (well, it is more alpha than beta as there are not even all features for this version included), which includes a new tone generator module. This is not (yet) supported by the editor, but if you are comfortable with directly editing XML, you can try to use this module for synchronization.

With the new audio output module, you can define the tone parametrically, so instead of actually calculating the waveform, you can directly set the frequency and phyphox takes care of maintaining the phase of the generated tone. There should be no clicking when changing the frequency and there should be no periodic clicking if the defined frequency does not match up with the sampling frequency. You can find the details in our wiki ( and you can have a look at the configuration file of the new tone generator in the development branch on githubg ( Note that the waveform is only calculated in this example to display it to the user.

Also, you can now try a different technique that might be interesting to those of you who are working with resonances. The beta version allows you to generate white noise in the audio spectrum experiment (Settings, below the number of samples), so you can feed the white noise into your resonator and can see the amplified resonant frequencies in the audio spectrum.

You can join the public beta test at The Android version should be available within an hour (maybe a bit longer due to caching of the Play Store app) and the iOS version right after Apple has reviewed this version (probably tomorrow).
