The Levelator® Change History

Known Bugs and Limitations in Version 2.1.1

If an .mp4 file was submited it was reported as an .mp3 file. (Neither are accepted by The Levelator.)
Attempts to Levelate compressed files (ie, other than WAV, AIFF, etc.) are now detected and reported in a more friendly manner.
If the source file can't be opened (eg, due to a permissions problem) a better error message is displayed.
"New Version" alerts are now displayed even for minor updates if specified on our servers.
When installing a new version, the program did not always display the "news" file on first startup (OS X only).
There were a variety of problems under OS X:
- Version 2.0.3: Audio files could not be processed on PowerPC Macs under OS X 10.4.x. (The visible error message began ""Level reports: dyld:lazy symbol binding failed: Symbol not found")
- Version 2.0.3: A permissions error was reported on a variety of OS X versions and configurations.
- Version 2.1.0: Failed on PowerPC Macs (all versions of OS X).
When installing a new version, the program did not always display the "news" file on first startup (OS X only).

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.

Windows 2000 is no longer supported.
The Levelator® cannot open files created by Adobe Soundbooth. We're waiting for a fix in libsndfile 1.0.18.
The Levelator® cannot open some AIFF files created by Soundtrack Pro 2. We're waiting for a fix in libsndfile 1.0.18. Workaround: Save as WAV file.
The Levelator® cannot open some WAV files created by Adobe Premiere Pro. We're waiting for a fix in libsndfile 1.0.18. Workaround: Save as AIFF file.
The Linux version is locked to Ubuntu 7.10 x86.

When the app is (re)installed, it clears its cache of the new "phone home" message.
If you right-click on an audio file, Send to... allows you to start The Levelator®. No longer does this leave an additional instance of the application running each time.
The Levelator® appears in the Windows task bar. (Windows only)
The Levelator® is included in the Alt-Tab display of running applications.
Error messages no longer include cryptic characters such as "\n".

Now accepts filenames containing spaces.
Now processes very short audio files.
Accessibility for visually-impaired users:
- Windows only: Right-click on a source audio file, select "Send To" from the menu, then "CN Levelator®".
- OS X only: With The Levelator® as the active application press Command-o for a File|Open dialog box
Windows installer now includes MSVCP71.dll, which previously had to be downloaded by some users.
New desktop icon shows up better against blue screen backgrounds.
Killing the UI thread now terminates the entire application.
Added link to documentation of supported file formats.
The Levelator® "phones home" at startup to The Conversations Network (a) to check for new versions (as in the past) and (b) to check for infrequent promotional messages.
The license agreement has been updated to include a description of the phone-home behavior.

Fixed a bug that caused The Levelator® to crash when trying to Levelator® more than one source file.

A cool new interface.
Significant improvements in the levelation algorithms. (Thanks to all those who submitted challenging audio files. We used every one of them in our testing.)
- improved handling of background noise
- improved processing of stereo files
- fewer 'breathing" and "pumping" artifacts
All sample rates and bit depths are now supported. Previously, some such as 22,050Hz and 24-bit were not.
Renaming the application files to simply "Levelator" in order to make the application easier to locate in alpahbetized lists.
Elimination of the Java Web Start user interface in favor of a native UI for each platform.
Easing of restrictions on commercial use. (Read the new license.)
You can now drag-and-drop an audio file onto the application's icon, even if the application is not currently running.
The application window can now be minimized.
