# audition-sounds.sh — hear the mimecroft sound experiments.
#
# For each sound it echoes the name to the terminal and plays the
# sound immediately after — an A/B audition of every effect in the
# set, in the order mimecroft would use them:
#
#   bash audition-sounds.sh              # echo name → play, per sound
#   bash audition-sounds.sh --seed 7     # one seed for all licks
#   bash audition-sounds.sh --repeat 2   # each sound twice
#   bash audition-sounds.sh --preview    # visual only (ASCII scopes)
#
# Needs host bash (printf -v to build the WAVs) and an audio player:
# aplay / paplay / pw-play / play / ffplay / cvlc, first found wins.
# With no player — or when the player fails (e.g. a headless box with
# no sound card) — each sound falls back to its ASCII oscilloscope, so
# the audition still "plays" visually. No `exit` anywhere: the
# transpiled shell's exit kills the whole session.
