# This is a quick CLI tool to preview a folder of audio samples.
# Run it in a directory with some .wav files.
# Uses mplayer to trigger playing the sounds.
# Currently it loads up as many samples as will fit on the keyboard (lowercase letters)
# In the future it will allow you to change directories, page through samples on the keyboard and maybe some other fun stuff.
