I use Windows Media Player to play sounds. Click on the above image to identify the file calific01a.wav containing three sounds from the neck of the bottle. I give the sound's URL to the Player, then minimize it so I can see the copy of the spectrogram while listening to the sounds online.
When you are working offline, note that Gram.exe has a cursor that is used to measure frequency of events. All three fundamentals of the sounds are at 371 Hz. You can Toggle Grid to show a frequency scale.
Measure frequencies of the two harmonic lines above each fundamental.
