LEVELATOR VOCALS FOR MAC OS X

The Levelator is available for Mac OS X (10.9 and above), and Windows (95 and above, including 10 and 11). The Levelator does its own normalization – plus, you won’t be able to match your performance and volume if and when you have to do pickups with the raw audio if you’ve normalized it. Oh, and just in case you’re thinking you should peak normalize before exporting, don’t. Then, export your audio as an MP3 file and upload to ACX. You’ll see the height of the waveform reduce slightly (Oh, and yes, do leave that first box checked, the one that says “Remove DC Offset”) Open that file in Audacity, and use the Normalize… function to reduce that -1.0 db to -3.0 db.

wav file, in the same folder as your original, that has the suffix “.output.wav”. Warning – a moment of Geekspeak® ahead: The Levelator does one thing that is exactly what ACX wants you to do with your audio: it adjusts your root-mean-square (RMS) normalization to between -18 and -23 dB.īut, there’s one last thing you need to do: adjust the peak normalization (as opposed to the RMS normalization – they are two different things). Prep your raw voice tracks with The Levelator, then use your audio software’s tool to finish the job (peak normalizing to -3 dB and exporting as a 192k mono MP3 file – again, both things that AudioCupcake does automatically) before uploading it to ACX. It’s for the same reason AM and FM radio, and most podcasters, compress their sound – so you can easily hear them over road and engine noise, traffic, leaf blowers, airplane noise and more.

Why do this? So your listener can effectively compete with all of the environmental sounds around them, and hear you clearly. Which means that this tool that was created for podcasting, works great on your audiobook audio as well. Why? Because the levels have been adjusted so that they are uniform – uniformly louder. The upper waveform of the two shown below is your raw audio, and the lower waveform is what The Levelator (and AudioCupcake, explained toward the bottom of this article) does to enhance your audio: The Levelator scans your original audio, adjusts the volume levels of all of the audio as it goes along, and when it’s finished, creates a new version of your audio that has more matched volume levels and, well, just sounds better. A group of podcasters, led by Doug Kaye, created it in the early 2000s to solve a thorny interviewing-over-the-internet issue: two people talking on a podcast at different volume levels with different microphones.

LEVELATOR VOCALS HOW TO

So, I now also teach others how to use it, both in the VOHeroes curriculum and in the course I teach with Dan O’Day, the ACX Master Class. There’s yet another tool that I use, that has been orphaned from its previous use, but still works great. In ProTools, Logic, Audacity and other sound software, you can adjust RMS normalization, as described in ACX’s production and mastering standards: One solution is to add compression to your audio, either with a microphone pre-processor, or in your sound software. These two facts are at odds with one another. ( UPDATE: If you’re a Mac user, please scroll down to the section below on AudioCupcake – it does all that The Levelator does and more.)īecause audiobooks are listened to by people in high noise environments (cars, trucks, planes, etc), it’s imperative that every single word you say as an audiobook performer gets heard.Īnd sometimes, when you have a microphone with little or no pre-processing, the levels you speak at can vary greatly.

LEVELATOR VOCALS DOWNLOAD

Better yet, download AudioCupcake, which has superseded The Levelator for Mac users.Click this link to download The Levelator for Windows.Click this link to download The Levelator for Mac.Here are links to download three different items: You’ll find a few links to download this tool (and the one that superseded it) at the very top of this article. From the world of podcasting production comes a tool that is also very useful if you’re narrating audiobooks, especially if you want to be compliant with one of ACX’s standards in one simple drag and drop step.
