![]() Interested users can download the free program from the project website. The Levelator is offered for Windows, OS X and Linux based operating systems. That may be fine if it is one or two audio files that you need to correct, but not so much if we are talking about dozens or even hundreds of files. Many podcasts are not offered as wav files but mp3, which means that you will have to convert the mp3 files first to wav before you can use the program to level the audio. Its not a compressor, normalizer or limiter although it contains all three. The Levelator is a software that runs on Windows and OS X that adjusts the audio levels within your podcast or other audio file for variations from one speaker to the next, for example. The big limitation of the program is the short list of supported audio formats. Software » Audio Encoders » The Levelator 2.1.1. So we asked him, "Bruce, do you you think you can write a leveler that corrects for medium-term variations in loudness instead of the short-term and long-term variatons processed by compressor/limiters and normalizers, respectively?" Bruce and Malcolm took on the challenge, and eight months later we began testing The Levelator. (It's not actually that simple, but the metaphor is helpful.)īruce, with help from his son, Malcolm, had proven that he knew how to tackle these problems in ways that no one else anywhere in the audio/software industry has done to date. Software can do better by performing multiple passes over the audio, generating a loudness map of where the volume changes. Despite its developers saying they had no plans for future updates years ago (see The Levelator 2.1. Even a skilled human can only react to changes unless s/he is lucky enough to be present during a recording session and can use visual cues to anticipate coming variations. ![]() Here are some hardware devices such as various AGC (automatic-gain control) components that can do moderate leveling, but since they have to operate in real time (i.e., without look-ahead), they can't do much. The developers reveal a bit about the background process on the program website: The modified audio file is then in the end saved in the same directory as the original file. While Articulate allows you to normalize your audio upon publishing, I’ve learned that normalizing doesn’t really do everything you might want (or expect) it to. The program displays a progress bar while doing its magic. All you need to do to level an audio file is to drag and drop it into the program interface. The Levelator comes without options or settings. Usage on the other hand could not be simpler. Only wav audio and aiff audio formats are supported by the program. The supported audio formats are without doubt the greatest restriction or usability issue.
