+# to_mp3.sh — Convert .m4a and .wav files to .mp3
+#
+# Usage:
+#   ./to_mp3.sh <file_or_folder> [options]
+#
+# Options:
+#   --quality N    VBR quality 0-9 (default: 2 ≈ 190kbps; lower = better)
+#   --bitrate N    CBR bitrate e.g. 192k (overrides --quality)
+#   --replace      Delete originals after successful conversion
+#   --dry-run      Show what would be converted without doing anything
+#
+# Examples:
+#   ./to_mp3.sh recordings/
+#   ./to_mp3.sh interview.m4a
+#   ./to_mp3.sh recordings/ --replace
+#   ./to_mp3.sh recordings/ --bitrate 128k
