Turn Up the Feedback: ACX Audio Analysis Now Checks Spacing

Have you met Audio Analysis? In case you haven’t been acquainted, we launched this tool (and its partner, Audio Lab) last year to give you instant feedback on your audio files, allowing you to identify and correct technical issues before you submit them to our QA team.

Audio Lab can be used to check any audio for important metrics like peak value and RMS. That means you can upload your auditions, your profile samples, examples of your production audio, etc. for our robot review. And if you don’t take that step beforehand, Audio Analysis checks your production audio files within each of your projects as you upload them. Together, this sound-screening dream team helps make sure you’re putting your best foot forward every time.

And now, in addition to the seven metrics this dynamic duo already assesses, both tools now check the spacing at the beginnings and ends of each file, to make sure they measure up to our Submission Requirements.

Accompanying this announcement, we’re adjusting our spacing requirement to improve the listener experience—going forward, all files must have no more than 5 seconds of “room tone,” or spacing, at their beginning and end.

We hope these adjustments help your audio achieve a seamless journey through our QA check, helping get your audiobooks to retail faster and making you (and your fans) happier. And if you haven’t checked out Audio Lab yet, give a spin to see how it can save you time and energy making your next big audition or production just right.

Sound Check: Audio Lab Launches on ACX

Earlier this year, we launched Audio Analysis — a web tool that gives ACX Producers instant feedback on their production audio files, allowing them to identify and correct technical issues before submitting their projects for review. Audio Analysis improves the workflow for Producers during a production, but we want all ACX Producers to feel confident about their sound before they even submit their first audition, so we created Audio Lab. Simply upload your audio files and Audio Lab gives you immediate feedback on how they measure up to our Audio Submission Requirements on seven important metrics, including peak value and RMS. We’re excited about the potential this tool offers for new and seasoned Producers alike, so we thought we’d break down how you can use Audio Lab effectively to hone your sound like a pro.

Who can use Audio Lab?

Audio Lab is open to any ACX user – if you have an account with ACX, you can upload files for analysis on Audio Lab. New producers can create an ACX account and start using it to test their sound progress as they learn to gauge when they’re ready to start auditioning. Seasoned producers can use it to test and calibrate new gear to meet our submission requirements.

How do I use it?

It’s easy! Just upload your audio files to the Audio Lab page – you can find it under the “Production Resources” tab on ACX – and the system will give you immediate feedback on how your files measure up to our submission requirements on RMS, peak value, bitrate, bitrate method, and sample rate. The results are only visible to you.

What sort of files should I use?

Audio Lab is built to analyze any spoken word MP3 audio files, but we recommend uploading files that you’ve recorded, edited, and mastered to our submission requirements as you would if you were producing an audiobook, even if you’re just reading test passages from a favorite book. This will give you the best sense of how production-ready your sound is, and will let you know what you need to adjust to pass QA.

When do I use it?

Anytime you have audio you want to test! Here are just a few times you might find it useful:

  • Use it to test samples for your profile when you first join ACX
  • Use it to make sure you’re ready to take on audiobook projects
  • Before auditioning for a specific project
  • When you’re mid-project, to test your audio before sending it to the Rights Holder for approval
  • Whenever you change your equipment or studio space

Why should I use it?

Periodically testing your files with Audio Lab – whether you’re a new narrator or an ACX veteran – ensures you enter into every contract with the confidence that you can deliver a great production.

We hope that Audio Lab offers the Producer community the resources you need to craft awesome productions.
