# record.sh — record a 90-second voice sample for ElevenLabs cloning.
# First run will trigger macOS mic-permission prompt (Terminal needs Microphone access).
#
# Usage:  ./record.sh [seconds=90] [output=~/Projects/voice-clone/sample.wav]
#
# What to read for the best clone (60-90sec, varied tone):
#   "Hi, I'm Steve. This is a voice sample for the Steve narrator voice on the
#   WhoLivedThere project. I'm reading at a normal pace, with natural pauses,
#   the way I'd actually narrate a product walkthrough. Open the archive for
#   every house. Public records, private memories, real addresses. Editorial
#   seriousness without being precious. Quick brown foxes and lazy dogs and
#   forty-two and three-thousand-eight-hundred-and-twelve."
#   (Add another 30-40sec of any natural speech. Whisper, normal, slightly
#   excited — variety helps the clone capture range.)
