Download final files. What format should I use?

Updated: Aug 5, 2021

We recommend to use the -16 LUFS "Mastered for web videos" for all projects that do not require any specific loudness standards.

-16 LUFS works in general on the web and for most other types of jobs. By working with the dynamically loudness masted files they will always have the same perceived level, regardless of what the voice talent has uploaded. This makes it easy to edit takes and to do pickups as they will match in volume directly. It also make it easy to produce loudness consistent (see tips: ).

All VO files in your project will be available in the following formats .

Mastered for web videos -16 LUFS

This is the best choice in most situations where no specific standard is specified. This file will work for standard web videos, e-learning, presentations etc. It's dynamically loudness masted in a neutral way that works in most cases.

Mastered for Internet ads -13 LUFS Use this for YouTube Pre-roll ads as they allow up to -13 LUFS. It is also a good start for many other types of ads but other platforms might have other LUFS standards. It's a little more aggressively mastered and slightly higher in volume.

Mastered for TV or R128 - 23 LUFS

Use this for TV (Europe) or any production where the R128 standard is specified.


Use this if you want to do all the work by yourself. It's the file originally uploaded by the voice talent. It can differ in volume between takes as no loudness or dynamical process is added by Voicemachine.

Preview Use this if you would like to share files in an email etc. Preview files are very small and sounds good enough to approve or make comments to the recording (the quality is not representative to original audio quality but they are loudness processed for consistent audio levels).
