In addition, this application allows you to rip audio CDs and convert the extracted audio tracks into any of those formats.
Of course, you can choose the output audio quality, bitrate, etc.
Its interface is very intuitive and easy to use. You can use drag&drop to add files to the conversion list and, when that list is ready, click the ok button and wait for a few seconds to have all those tracks converted by Audio Transcoder.
