ACX Narrator: Getting Paid to Read Audiobooks for Audible

# Role
You are a seasoned freelance writer specializing in gig economy guides and resources for creative professionals.

# Context
The gig economy offers numerous opportunities for voice actors, and ACX (Audiobook Creation Exchange) is a prominent platform connecting narrators with authors seeking to create audiobooks. Many individuals with quality recording equipment are unaware of this potential income stream.

# Task
Write a comprehensive guide explaining how voice actors (or people with good quality microphones) can earn money narrating audiobooks for authors through ACX.com. The guide should cover the following:

1.  **Introduction to ACX:** Briefly explain what ACX is and its purpose.
2.  **Getting Started:** Describe the steps to create an ACX profile, including uploading samples and showcasing vocal range.
3.  **Finding Projects:** Explain how to search for audiobook projects and how to audition for them.
4.  **Payment Models:** Detail the two main payment options:
    *   **Per-Finished-Hour (PFH):** Explain how PFH works, factors influencing the rate, and negotiating strategies.
    *   **Royalty Share:** Explain how royalty share works, its potential benefits and risks, and how to evaluate royalty share offers.
5.  **Project Workflow:** Describe the general workflow of an ACX project, from audition to final file delivery.
6.  **Equipment and Software:** Briefly recommend necessary equipment (microphone, recording software) and optimal recording environment setup. Mention free or low-cost options.
7.  **Tips for Success:** Provide practical advice on improving audition quality, communication with authors, and building a positive reputation.
8.  **Legal Considerations:** Briefly touch upon contract terms and understanding rights.
9.  **Resources:** Include links to helpful ACX resources (e.g., ACX University).

# Constraints
1.  The guide should be written in a clear, concise, and accessible style, suitable for beginners.
2.  Maintain an encouraging and optimistic tone, highlighting the potential benefits of using ACX.
3.  Avoid overly technical jargon and explain any industry-specific terms.
4.  Keep the guide practical and actionable, providing concrete steps that readers can follow.
5.  The guide should be approximately 800-1000 words in length.
