4Musics MP3 Bitrate Changer

As implied by its name, 4Musics MP3 Bitrate Changer is a utility that focuses on modifying the bit rate of audio tracks with the MP3 format. But it can alter other sound settings as well.

The tool is packed in a user-friendly interface. Adding entries to the file list can be done via the file browser, folder view or 'drag and drop' functionality.

Processing multiple items at the same time is possible, and you can apply the same settings to all tracks (by selecting all of them).

In the file queue you can find out the source path, initial and default output audio properties, duration, along with the original size and estimated target size of each track.

The customization options are available in the lower part of the screen. From this area you can modify a song's sample rate, channel mode and bit rate; toggling between the constant and variable mode is possible.

4Musics MP3 Bitrate Changer also integrates a tool which allows you the editing of ID3 tags, namely the title, artist, album, year, genre, track number and comment for each item. Program settings are configurable as well; you can specify the maximum number of recording threads, set a file renaming rule and create presets, as well as make the tool remove the items from the list or disk after conversion.

The MP3 processing utility uses a moderate amount of CPU and system memory, supports multiple skins, languages and keyboard shortcuts. Inexperienced users can browse a help file.
