#.mp3 levelator mp4#
I currently use CM levelator but this means that I have to go from MP4 to Wav then do levelator then back to audacity to get a 32 KB MP3 file to send to my clients via Email. However I have a question which no one seems to be able to help with.īasically, I have recordings of meettings done via ms teams where all members are at different levels so I am trying to make the voices all at the same level. I am a fairly new user who is also Visual Impaired so I use a screen reader to access it, therefore I am equally a member of the Audacityforblind list. I am currenctly using the latest version of Audacity on windows 10.

The Levelator is available for Mac OS X, Windows and Linux.Firstly many thanks for letting me subscribe to this forum. 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: Levelator does exactly what ACX wants you to do with your audio: root-mean-square (RMS) normalization at -20 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 before turning it in. 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 Levelator scans your original audio, adjusts the levels of the audio as it goes along, and when it’s all done, creates a new version of your audio that, well, just sounds better. A group of podcasters, led by Doug Kaye, created it a few years ago to solve a thorny interviewing-over-the-internet issue: two people talking on a podcast at different levels with different microphones.

So, I now also teach others how to use it, both in the VO2GoGo curriculum and in the project I do 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, you can use 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. And from that world, comes a tool that is very useful if you’re reading audiobooks, especially if you want to be compliant with ACX standards in one simple step.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.
