 	1. Switch `screm.exe`'s output to your desired output (e.g. "VoiceMeeter Input")
 	1. Change the default sound output to the previous value (e.g. "USB Sound Card")

+Yeah, so, there's this thing in audio files called a "sample rate". It's basically how fast the sound data gets played to the speaker. The [audio library I'm using](https://github.com/faiface/beep) is *supposed* to support different sample rates across your collection of sound files, but I've tested, retested, refactored, and cried over why that's not working so instead I hardcoded the library to expect 44100 as the sample rate and put a `fix-sample-rates.sh` script in `./sounds` that forces all audio files in a provided directory (e.g. `./fix-sample-rates.sh e-epic`) to 44100 `.wav`. That's the only way I've found to prevent crashes. Writing Screm Bot 3000 in Go was a mistake.
