The Levelator® 2.0 is Here


After more than ten months of work (and waiting for third-party components), I’m thrilled to announce the release of a major update to The Levelator®. Version 2.0.3 for Windows and OS X is now available for download. Some of the changes include:

  • A number of improvements have been made to The Levelator’s® algorithms based on sample audio files submitted by users. Most notably is a reduction in certain unnatural volume adjustments.
  • libsndfile has been updated to version 1.0.21 which has fixed the following:
    • 24-bit files are now properly supported.
    • Soundtrack Pro 2 .aiff files are now supported.
    • Adobe Soundbooth files are now supported.
    • Unicode filenames are now supported.
  • Very short source files are now supported.
  • You can now drag/drop and audio file onto the application icon in the OS X Dock.
  • The Levelator® now verifies that it has sufficient disk space for temporary and output files before processing the source file.
  • ctrl-o/cmd-o (Open File…) now works after alt-tab has been used to switch applications.
  • The .ini (settings) file is now deleted during installation in order to properly refresh the ‘news’ timestamp. (Fixed in Windows version only.)
  • The formatting of error reports has been improved.
  • Log files are now unique on a per-user basis.

    Mr. Kaye,

    Is the Levelator still a product? Is there a command line interface now? Per your post here did you integrate the leveler with audacity? What is the current homepage of the product?

      The Levelator still lives at It will likely never have a command-line interface, but not because anyone is withholding one. It’s just that the parameters to the algorithm aren’t related to how one normally thinks of theses things. Re Audacity, I don’t believe anyone has integrated it in any way.
