TravSonic is an audiobook post-production studio that bundles narration editing, human proof-listening and QC, and mastering into a single per-finished-hour service. It takes raw or rough-cut narration and delivers files that meet ACX and Audible technical requirements.

  • Best for: Authors and independent narrators who want one vendor to handle editing, proofing, and mastering rather than stitching together separate freelancers
  • Key features: Word-for-word script verification, performance and structural review, audio-artifact cleanup, and a proprietary automated audit engine for profanity and metadata checks
  • Pricing: From $149.99 per finished hour for the full editing-plus-proofing-plus-mastering package; optional add-ons ($45–$145) cover extras like music licensing and ACX upload assistance
  • Turnaround: 4–20 business days depending on word count, starting once files are received and the project is confirmed
  • Why authors choose it: Combines a human-driven deep-dive proof with technical compliance mastering, so the finished audio is submission-ready in one pass
