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.
