Terzosuono.ogg‎ (Ogg Vorbis sound file, length 20s, 28kbps)

[edit] Summary

Description	Two tones which start in unison at 600 Hz, but, while the left channel stays at a constant pitch, the frequency of the right channel rises by 5 hertz per second. Firstly, a beating is heard, then a Tartini combination tone appears.
Source	I created it with a program I wrote and encoded it with oggenc (`./terzosuono \| oggenc -r - > terzosuono.ogg`).
