LL2MP3 is a frontend application that converts flac, ape and wav audio files to mp3.

LL2MP3 main window


  • Transfers ID3 tags
    If ID3v1 or ID3v2 tags (e.g. artist, title, album) are present in a flac or ape file, these are transferred to the mp3 file.
  • Drag-and-drop interface
    Drop flac, ape or wav files (or a combination) on the application window to convert them to mp3.
  • Automatic recursion
    When a directory is dropped on the application, it processes all files in the entire directory tree. The directory structure is replicated in the location where mp3 files are saved.
  • Uses free codecs
    The actual conversions are performed by existing programs (codecs) which are available free of cost.
  • Flexible mp3 settings
    There are several standard mp3 encoding presets available. Advanced users can create their own presets to control every aspect of the mp3 encoding process.

Converting FLAC (= Free Lossless Audio Compression), APE (= MAC: Monkey's Audio Compression), and WAV audio files to MP3 (including tags) is easy with this frontend. The frontend uses recursion, this means that it processes all files as well as all of the subdirectories of directories dropped onto the program. You can also start multiple instances, which is useful if you have a multi-core system. 

Download, unzip in a directory of your choice. The zip also contains a small auxiliary program "sleep.exe". It should reside in the same directory as LL2MP3.

A selection of files and directories can be dropped on the program window: all FLAC, APE, and WAV files in the selection will be processed. You can drop more files and directories while the transcoding is going on.

Note that the frontend uses these existing codecs:

If you are only interested in converting FLAC files you may omit the APE codec, and vice versa. LL2MP3 checks at startup which codecs are available and indicates which conversions are supported accordingly. If both APE codec and FLAC codec are absent, you can still convert WAV files to mp3 files.

Step-by-step instructions on how to obtain the required codecs and how to make them available in LL2MP3 are found in the LL2MP3 Quick start guide. For more detailed information, a comprehensive  LL2MP3 Help is available in PDF format.

LL2MP3's context menu contains 13 items to help you configure the program. One of these, 'Lame Encoding Options', opens a submenu of which the right half gives you a choice of 5 standard settings (128 kbps, 192 kbps, standard, extreme and insane); these cannot be changed. The left half shows what custom settings for the Lame encoder are available. These can be edited by clicking 'Custom Settings:'. The custom settings' names appear in the left half of the submenu. The currently selected setting is marked by a black dot. This selection and the settings themselves are saved to the registry, so they are available the next time you start the program. A separate menu item shows the Lame help text to help you define your own custom settings.

Via the context menu you can select the mp3 destination directory. Instead of specifying a destination directory, you may also choose to automatically save the mp3 files in the same directory as the source files. The cue list, tags list, and error list can be viewed while processing is going on. Some of the errors that might occur during the conversion processes are collected in this error list. If a custom encoding string is not recognized by Lame, error messages appear also. To test for FLAC or APE decoding errors only, check the menu item 'Verify only'.

I have tested the frontend with a variety of FLAC and APE files, but it is possible that some files made with older or newer codecs cause problems - just try and see. It runs on Windows 7, Vista and XP.
