This is my cat charlotte recorded with two yamaha pocketrak recorders placed in front of a peavey bandit 65 amp set on reverb. I used an audio-technica mic to record her meow's and ended it with her motor boat purr. :^)if you use it please comment on what you will use it for. Thanks. :^).
This tone was generated using audacity. In the base there is a 45hz sinusoid. Then a new sinusoid tone of 207hz is added for about 5s. After a pause of about 5s a second sinusoid of 208hz is added for 5s.
