123 Audio File Converter is an application designed to help you encode audio tracks to various formats, including MP3, MP2, AMR and MP4. The tool can be easily handled by all user levels.

The interface of the program is plain and simple to navigate through. Audio tracks can be imported into the list by using either the file browser or "drag and drop" method. Batch processing is allowed.

In the queue you can check out the source path, duration, format and status of each track. So, after you establish the destination folder and extension, you can proceed with the encoding job.

Furthermore, you can listen to tracks in a built-in audio player and enable 123 Audio File Converter to automatically turn off the computer after encoding, as well as configure audio settings when it comes to the sample frequency rate, channel mode, bit rate, encoder quality, type object, and others.

The audio conversion software requires a low-to-moderate amount of system resources, has a good response time, supports several keyboard shortcuts, quickly finishes a task and manages to keep a good sound quality in the output audio tracks. There's also a well-drawn help file that you can look into. Too bad the interface is outdated. Otherwise, we strongly recommend 123 Audio File Converter to all users.
