Energy/loudness normalization tool for batch processing Sound files

LS Levelator is an energy/loudness normalization tool for batch processing of large amount of files. This tool not only makes use of local energy variation but also takes into account the industry loudness models to produce an acceptable broadcast standard normalization.

The batch process is expected to help localization and broadcast professionals to render the speech dynamics much more efficiently and effectively.

Processing Modes

  • Simple: This is a traditional normalization w.r.t. the maximum peak level.

  • Static: This mode normalizes a signal from the average loudness to the target loudness, with constrains defined by the peak level. When "Segment Based" processing is enabled, it allows to apply respective normalization to the automatically detected signal segments.

  • Dynamic: Similar to Static mode, Dynamic mode further allows adjusting the loudness dynamics among segments. When "Global Normalization" is enabled, all segments detected in all the input files are taken into account for deriving the best loudness distribution.

Processing Options

  • Suppress Noise: Prevent normalization in the automatically detected noise region.

  • Segment Based: Treat automatically detected segments independently.

  • Peak Limit: Peak amplitude limit allowed for normalization.

  • Global Normalization: Derive loudness distribution from all the input files.

  • Global Max Peak Limit: For Simple mode processing, normalize with respect to the maximal peak in all files.

iLok License

This product requires an activation!
You can either "soft" activate on your computer without addditional hardware or transfer the license to an iLok USB dongle which has to be purchased separately. The iLok dongle can be used to run the protected software on different computers. Your licenses can be easily manged using the iLok Licence Manager. To protect your investment against theft or loss we recommend the iLok Zero Downtime protection with TLC.

An internet connection on any computer and a free user-accout at is required to authorize the product.

Please check with the software manufacturer which iLok version is required at least if you want to use a hardware iLok!
