Artificial beep used for research purposes in the behavioral experiment (link to the paper: http://www. Ncbi. Nlm. Nih. Gov/pmc/articles/pmc3384222/). The sound was generated in matlab using binary click trains at the fundamental frequency of 330 hz and 100 ms duration, which were bandpass filtered with a bandwidth equal to 1/50th of the formant frequency using malcolm slaney's auditory toolbox. Formant center frequency was 6. 912 khz. The formant frequency was chosen to lie within rat and human sensitivity range.

This is a sound made in audacity with a high frequency square wave slowed down. I have a question about this effect that sounds like a robot saying ''uaiuai'' ¿which is the name of this effect?if someone knows the name, please comment.

Using a frequency filter by setting its oscillations in variable arrays i was able to make most of these sounds. Also vocoding and feedbacks and feed throughs were happening. Then they were altered in audacity.

Generated tone, some little distortion, frequency cut, combined with itself with lower pitch.

A model i made in blender imported raw in audacity(warning: high frequency noise).
