Acoustic Soundboard is a free, open source program for Windows which strives to be easy to use and lightweight. The main purpose is to conveniently play audio files to others while allowing the user to hear what is playing and still use their microphone normally. There is no installation required, simply unzip the contents wherever you like. On closing, the soundboard will automatically save the user's last devices, sounds, and hotkeys to a database file. View a demo video here https://www.youtube.com/watch?v=cPdncc-q1oM If you want others to hear your microphone and the sounds you play, you will first need to install a virtual audio cable such as this one: https://vb-audio.com/Cable/ IMPORTANT: Windows may warn you that this program contains a virus because it hooks the keyboard. Your data stays on your computer only. Please see the readme for more information.
