This is the popular "start!" sound heard in arcades and some home 8-bit video games. It can also be used as, a car starting? jumping? maybe a gun reload? free to use, but please give credit where you use it! thanks :). --recorded from famicom-on-a-chip hardware--.
I took another sample from a malfunctioning arcade cabinet, this time giving off a repetitive droning hum. Listening to it without context, i imagine being in a control center containing heavy industrial computing machines.
Win announcement recorded with my own voice with a tascam dr-05 v2 and processed on adobe audition cc. Based on old retro sounds from arcade games like street fighter. You can grab it for free for your project.
