Does levelator contain viruses software#
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. There 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. It doesn't make the kind of adjustments that a skilled audio engineer can perform in software or at a mixing console, riding the levels up and down to compensate for medium-term variations. The CNUploader's normalizer acts similar to an intelligent RMS-based compressor/limiter combination, and it therefore affects primarily the short-term (transient) sounds and the long-term overall loudness of the file. One of our best engineers, Bruce Sharpe, offered to write a standalone software RMS normalization utility, which we've been using as part of our production system CNUploader since 2005. We limped along for many months using the RMS normalization functions in various applications, but the results weren't satisfactory and it required tools and skillsets that some of our post-production audio engineers didn't have.
When we developed the IT Conversations component-based show-assembly system, we realized all the components had to be of the same loudness or the results would sound awful. The Levelator® is unlike any other audio tool you've ever seen, heard or used. Have you ever recorded an interview in which you and your guest ended up at different volumes? How about a panel discussion where some people were close to microphones and others were not? These are the problems the post-production engineers of Team ITC here at The Conversations Network solve every day, and it used to take them hours of painstaking work with expensive and complex tools like SoundTrack Pro, Audacity, Sound Forge or Audition to solve them.
