![]() Interested users can download the free program from the project website. Lawrence Flynn competed for Canada in the mens standing volleyball event at the 2000 Summer Paralympics, where he won a silver medal. 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. The big limitation of the program is the short list of supported audio formats. 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. 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. 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. EDIT: New version is out with more features My recommendation now is to switch from Auphonic to Loudness.fm for a cleaner interface thats designed specifically for podcasters.-In my testing, the levelers of Loudness.fm and Auphonic produce similarly great results on speech. 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. Meaning I wanted the quiet bits louder and the louder bits quiet for a better listening. when I first started out in podcasting I struggled to level or 'normalise' my audio. ![]() While leveling the audio of podcasts, interviews and panel discussions is the core purpose of the free application, it can be used to level and normalize any kind of supported audio format. I realise this isnt going to be for everyone BUT.
