Checker is a tool that looks for common problems with recordings for LibriVox, a site where volunteers collaborate to make audio books of public domain texts. The Checker tool can save you time by checking your file for common issues before you go to the trouble of uploading it.

It does ''not'' check the content of the recording (such as reading the wrong word), nor the quality of your performance.
  
To use Checker, drag and drop one or more MP3 files (or a folder or ZIP archive that contains them) onto the Checker window and allow it to analyze them. Once it is done, click on any file to see a report of any issues that were detected. The report will either state that the file "passed" (no problems were detected), or it may list a number of errors or warnings. Errors generally indicate more serious problems that should be fixed before uploading the file. A warning is a less serious problem, or in some cases a potential problem that Checker is not sure about.

What does Checker Check?
 
  
The program checks many technical features about your file. It can find problems with file name conventions, metadata (ID3 tags), audio format and MP3 encoding options, volume, and more. Checker has also been designed with extensibility in mind, so other programmers can easily add new tests (or modify the existing ones) in the future.

The report will either state that the file “passed” or else list any issues as errors or warnings. Errors are serious problems that should be fixed before uploading the file. A warning is less serious, or in some cases a potential problem that Checker is not sure about.

Windows: Download and run the installer as you would any other Windows software. If you get an error message when you try to run the program, you probably don't have Java installed. See below for help.

If you run into problems, make sure you have not disabled Java in your browser.
 
 
OS X: Download the .zip file and double-click it to open. Then drag the Checker icon into your Applications folder to install it.
 
 
 
Other: Download and unzip the JAR file. On most platforms, you can double-click the JAR file to run it. If that doesn't work for you, you can it start it from the shell using a line like: java -jar checker.jar
 
 
 
== Java Help ==
 
 
 
 
 
Checker was written in the Java language, so it will run on all of the most popular platforms, including Windows, Linux and OS X. It works best with version 6 of Java, or newer, but it will also run under version 5 with reduced functionality.
 
 
 
If the button does not work (for example, if you have disabled JavaScript in your browser), use one of the following links instead:
 
* Linux, Solaris, and Windows
 
* OS X: Apple JRE (download through Software Update)
 
 
 
 
 
== Ways You Can Help Out ==
 
 
 
 
 
Things you can do to help now:
 
 
 
* Writing additional "mini help" files to accompany the various tests.
 
* Suggesting language that will be friendly to novice LV volunteers.
 
* Throw a lot of MP3s at it so that the decoding and analysis system can be made as stable and reliable as possible.
 
* Report any bugs (or submit fixes).
 
* Provide feedback about the results and/or sensitivities for the various tests.
 
 
 
Things that will be possible later:
 
 
 
* Translate the default English localization files into other languages, as demand dictates.

Checker: An Audio File Validator for LibriVox Contributions

Checker, showing validation of an audio file

Checker is an open source tool that looks for common problems with Librivox recordings.

You can download the tool from the developer's website, here. The current version is release 0.96i, dated 11 January 2019.

What does Checker do?

Checker looks for common problems with your Librivox audio recordings. It can save you time by checking your file for common technical issues before you go to the trouble of uploading it.

The program checks many technical features of your file. It can find problems with volume, MP3 encoding options, audio format, metadata (ID3 tags), and file naming conventions.

It does not check the content of the recording (such as reading the wrong word), nor the quality of your performance.

How to use Checker

To use Checker, drag-and-drop MP3 files (or a folder or ZIP archive) onto the window, then wait for it to analyze them. Once done, click a file name to see a report of any issues that it found. The report will either state that the file “passed” or else list any issues as errors or warnings. Errors are serious problems that should be fixed before uploading the file. A warning is less serious, or in some cases a potential problem that Checker is not sure about.
