Physics apps - sound 2

In this post we briefly review two apps used to generate sound.

The writer found the app 'PA tone' to be good for producing a constant tone of a specific frequency (0-20kHz) assuming your speaker can handle it. Frequency selection was easy and fine control possible. There was also a choice of waveforms.

Also useful for certain situations is the app 'FG' which gives a tone starting at one specific frequency (0-20kHz) and ending at another selected frequency.
