Real-Time Voice Changer Software Development

I'm looking for a talented developer to create a Windows-based, real-time voice changer software for me. This software should be able to transform live voices from male to female and vice versa, with a realistic age adjustment feature (making the voice sound younger or older). The ultimate goal is to have a software that works with zero delay and produces natural-sounding voices, not robotic or fantasy-style.

Ideal Skills:
- Proficiency in Windows software development
- Experience with voice modulation technology
- Ability to ensure zero-delay operation

Key Requirements:
- Transforming male voices to female and vice versa
- Realistic age adjustments
- Producing natural-sounding voices

Experience with creating similar software or applications will be highly regarded. Please provide examples of relevant past work in your proposal.
