Design a sleek and modern monogram logo for an audio engineer with the initials "RW". The letters should be geometric and sharp, with a subtle waveform integrated into the "R" without overpowering the design. Use a black-and-white base with a touch of gold accent. The logo should feel sophisticated, minimal, and luxurious, similar to high-end brands like Chanel or Tiffany.  --ar 1:1 --s 50
