Schedule a Call

Ready to send us your audio files? Here is a helpful checklist.

1. Export all audio files no lower than 16 bit/44.1k Wav files. Both mono and stereo are accepted. No lossy formats such as mp3.

2. All exported audio should not have extra processing such as extensive EQ, heavy compression, limiting, noise reduction, or effects. Light compression and EQ are satisfactory as long as it is at the same settings during the recording process.

3. If the audio has already been edited, be sure it is free of region clipping. No head or endpoints are cut off and has some crossfades.

4. If sending unedited audio, please include all outtakes, voice cues, and retakes preferably all in the recorded file per section.

5. Label all audio files according to the table of contents of the audiobook numbered in order such as: Opening credits, 2. Introduction, 3. Chapter 1, etc.

6. Include the final book script, eBook, or Kindle version for reference. The print version can also be mailed.

7. Include any notes that may be helpful to the editing process.

8. Copy all audio files in a folder and send them using your preferred file sharing platform such as Dropbox, Google Drive, WeTransfer, etc. Do not send files as email attachments, please.

Q: Do you offer customer financing for installment payments?
A: Yes, TravSonic offers financing through Afterpay. Just pay your first installment upon your purchase of $500 or more ($2000 limit per project). You now have the leisure of starting your project today and paying overtime. Learn More

Q: Have we successfully uploaded finished audiobooks to websites such as Audible?
A: Yes, we’ve finished audiobooks successfully and they have been accepted for publishing on major audiobook websites. We will guide you every step of the way. Publishing your audiobook on ACX is included with this package.

Q: When I select a quote, do I have to purchase it?
A: No, the quote process is to get an approved estimate. We believe in first giving a free evaluation of your project. Once we feel confident that the project can be fulfilled and you approve the estimate, a payment is required.

Q: What is counted as a revision?
A: Revisions are changes to audio requested by the client during the entire project period. Often referred to as an ‘edit’, a revision typically takes the form of multiple edits done in one sitting. For example, one revision could consist of many edit changes and not just one edit per revision. Many projects take about 4 to 5 full revisions.

Q: How do I pay once I approved an estimate?
A: We will send you an invoice via email to make a secure payment online. If you wish to make a different payment method, it can be arranged.

Q: For how long are quotes valid?
A: Quotes are valid for 30 days from the issue date. This is a no-obligation quote and does not enter you into a contract or payment.

Q: After I have submitted my online project quote, what’s next?
A: Upon placing your quote, a TravSonic representative will contact you to discuss your potential project and customize your package further.

Q: I made an edit to my project after submitting it. Can I submit my files again?
A: Yes, this would count towards your complimentary revisions.

Q: When does my project start for the turnaround time?
A: Your project date starts once you have approved your quote, a payment has been made and all the project files have been received.

Q: Can you mix my project for different formats?
A: Yes, we can tailor your project to any sound spec needed for final delivery.

Q: Why are quote options available and not purchases on this website?
A: We believe in evaluating your project to get to know your needs and vision first. Since every project is different, we want to make sure you get exactly what is needed and you feel comfortable. This also ensures the best quality service to our customers.

Q: Can I have my files mailed to me?
A: Yes. We can mail your files on a portable hard drive, flash drive, or other media. This would be an extra fee.

Q: How many audio editors do we have working on an audiobook?
A: Up to 3 editors work on an audiobook at one time. This helps speed up the editing and production time.
