TravSonic’s audiobook editing, proofing, and mastering services come with a wide selection of optional add-ons. The outline below provides a full description of each.
ACX Cover Art Compliance Conversion (1:1 Square Ratio)
The distribution process demands precision. Your stunning print or e-book cover often fails to meet the strict digital platform specifications. We bridge that gap.
- The Problem We Solve: Audiobook cover art submission to digital platforms such as ACX requires a non-negotiable 1:1 square ratio, adhering strictly to defined pixel specifications. This differs from the rectangular format commonly adopted for printed and e-book covers.
- Our Deliverable: Customized, expert analysis reformatting—adjusting all specifications, from text and graphics to exact cropping and resizing—to guarantee compliance with exacting standards.
Mastering for Mobile: Audiobook .m4b Conversion
Give your listeners the best possible experience on their devices. The industry-standard .m4b format elevates the functionality of your audiobook.
- The Value: The .m4b file type is purpose-built for audiobooks. It offers intelligent bookmarking and automatic playback position saving for a superior, uninterrupted mobile experience.
- Our Process: We take your completed, chapterized audio files and consolidate them into a single, high-fidelity .m4b file, perfectly prepared for platform distribution or direct sale.
Signature Intro/Outro Music Design & Licensing
Establish a professional audio brand from the moment your listener presses play. A distinct musical signature creates a cohesive, high-end listening experience.
- A well-crafted audio signature is essential. A professionally selected and integrated musical theme will bookend your production, instantly elevating it from a collection of chapters to a distinguished and memorable product.
- The Full-Service Package: We handle the entire process: sourcing, selection, and securing the necessary royalty-free license for high-quality background music matched to your genre and tone. We then master the tracks and seamlessly weave them into your final audiobook production.
- Note: Includes all necessary documentation (proof of licensing/rights) required for distribution.

Get a versatile, universally compatible audio file optimized for all your marketing and promotional needs, without compromising quality.

Ideal for Quick Deployment:
