Two ever rising shepard tones rising at different rates overlaid by a pulsing hiss. This is a sound effect used to indicate a steadily approaching peril. It can be seamlessly looped.
I have been working on my twelve-tone program (in chuck). 1 - random 12 tones with random note-length for prime. 2 - then retorograde is played. 3 - after that prime and retrograde at the same time (3 times). Here the note-length is a average value.
Exploring the medium wave frequencies. Everything here sounds creepy. Radio used was a grundig yacht boy 207 with a broken antenna, recorded on a tascam dr-05x.
A simple 440 hz tone (sine) created in audacity. Or at least that's what it's supposed to be. . . For some reason, when i uploaded it, it sounded all distorted.
A increasing target lock tone i generated for a personal project. It is rough and meant to be tweaked for your needs. Sound is supposed to emulate an electronic weapon lock sound.
New linear scale. Made in python. . . 200hz up to 2000hz and back in steps of 100hzi'm not that convinced the beep command outputs exact frequencies. . . And the sound is terrible. But it is a beep. . .
Rauhigkeit 1 Apser = Sinus 1000 Hz und Sinus 1070 Hz gleichzeitig.The sound of a harshness of 1 asper = a sine wave tone of 1000 Hz 100 % modulated with a sine wave tone of 70 Hz at 60 dB sound pressure.
This is a perfect 1/10 second long 1khz tone like it is also used in film countdowns ;) u can also use it for a censor-tone: just copy&paste it again and again and ull get a longer 1khz tone without any jumps or hoverings.
This is a modified version of "earthkiller background 1", the background noise inside a space station. I removed some upper midrange (1700 hz) to make it easier to mix with dialog.
Relatively quiet suburban neighborhood ambience/room tone. No people, distant cars in the background, light wind. Recorded with a rode-ntg3 and zoom f4.
Recording of my office before anyone else is in. The only sound apart from the faint fan noise is a regular, very, very faint beep from something every few seconds (approx. 3. 7 khz). Zoom h5 with xyh5 capsules.
This tone is 485hz, slightly below the note b3 (493. 8hz). It's roughly the same frequency of the b tibetan bell in this package. End and start are well glued into a continuous wave (tested in unity 3d). Made with audacity.
