LameXP is a tool designed to convert audio files.

In the user-friendly interface you can add a file to encode (it also supports batch conversion), but you can also use the drag and drop method while you are browsing for files in Explorer (a floating dropbox is displayed on the lower right corner of the screen).

Once you have specified the output destination, you can edit meta data (it will supersede data from the source), enable or disable LameXP to automatically generate a playlist file (M3U), as well as configure compression and advanced options.

The format of the converted file can be MP3, OGG, Aften A/52, FLAC or WAV. In order to convert to AAC, you need to manually download the codec files in the LameXP installation files.

In addition, you can select rate control method (quality-based, average bitrate, constant bitrate), and adjust the quality/bitrate ratio (from level 0 to 9).

If you are an advanced user, you can also adjust the LAME algorithm quality - from poor quality (very fast) to best quality (very slow), enable bitrate management for LAME and OggEnc2, select sampling rate and MP3 channel mode, enforce stereo downmix of multi-channel sources, enable volume normalization filter, adjust treble and bass, set a rename pattern, adjust multi-threading, and more.

We tested LameXP by converting one 8.19MB MP3 file to WAV and FLAC. We used the default settings, and LameXP managed to successfully convert the files in remarkable time (only a few seconds). The output files weighed 57.8MB (WAV) and 45.7MB (FLAC).

It even alerts you with sound when the task is completed, and during conversion you can view overall CPU usage (which is low) and physical RAM usage.

In conclusion, LameXP is an excellent software for converting audio files, and we strongly recommend it to all users. It is free.
