This sound was from a live video feed on a social media broadcast. At some point the audio just got caught into a feedback loop that lasted for a bit. I thought it sounded interesting and saved it. Has kind of a laser or phaser cannon kind of thing going on. Perhaps an alert sound of some sort. Probably many possibilities for usage.
Here is my attempt at making a startup sound for a video game system reminiscent of the sounds from playstation or xbox systems. I made it about 4 years prior to uploading, as the idea didn't cross my mind until now.
I generated a square tone with audacity and applied a few effects to it, mostly wahwah i think, and faded in and out. If you repeat it, it makes a very believable sound for an old video game machine.
I generated four square tones with increasing silence in between with audacity. The tones are the c major scale. It is very useful in old video games when you win or do something good.
A simple chromatic sfx i made for a title screen. Can be used for power-ups, jumps or other ideas. Normally would strictly be an 8 bit sound, but with the reverb it can pass for something from the snes era. This is part one of two. The next file is the same thing with a higher pitch.
