![]() 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. 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. Better yet, download AudioCupcake, which has superseded The Levelator for Mac users.Click this link to download The Levelator for Windows.Click this link to download The Levelator for Mac.Here are links to download three different items: You’ll find a few links to download this tool (and the one that superseded it) at the very top of this article. This lets you replace your existing audio files in your presentation and keep the timings and settings you already have.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. (There isn't any editting options here Levelator seems to normalize and compress to a preset level, simple!)Īfter the files were converted I changed the file extension and name back to the original file extension and name that was in the original keynote folder and replaced the original keynote audio files with the newly converted ones from Levelator. Levelator batch normalizes and compresses your files and outputs them with a new file extension once converted. I then copied all the audio files that were stored in my presentation folder and converted them to AIFF ( Levelator only normalizes WAV and AIFF files) and dragged them into "Levelator"s conversion window. This changes your keynote presentation into a normal compressed folder. Here is my process for correcting the audio for anyone that may be looking for a way to normalize their audio clips:įirst I changed the file extension for my keynote presentation and changed it to. This was a great suggestion and it solved my issue although I wish there was something natively, I am so grateful for this suggestion.
