A sound stimuli to demonstrate combination tone from speakers. You should hear additional frequency of 500 hz. The sound itself is summation of1000 hz and 1500 hz.
To create this sound, i created a sinusoid of 500 hz and an amplitude of 0. 8. I then multiplied the speed of 0. 750. To get this final sound is to duplicate the sinusoid several times.
Recording of a room tone in medium sized, circular, carpeted room. A lecture can be distantly heard through a pair of doors. Recorded on an h2n zoom recorder, m/s raw setting.
A neutral, static room tone - with some reverb og distortion. I have used it in the background for radio shows, when recorded in a studio that's too silent - but of course mixed down a lot so you can just barely hear it.
Two descending tones. Made in garageband. Used for a production of sideways stories from wayside school for the "video intercom", this is the sound it made when it went out. Edit: i see a lot of people are enjoying this sound! if you'd like to donate a dollar or two towards my personal starving artist fund here is a donation link: https://www. Paypal. Me/baharv89.
