Installation is quite straightforward but you do need to pay attention to the wizard as we experienced two steps that tried to install extra programs at the same time. 

The interface is easy to use and will be familiar if you have used any other of Freemake's software. Click on the Audio button to add tracks and then one of the buttons at the bottom to select an audio format. It is possible to tweak the settings for each for the formats should you wish to choose a different quality setting.

Supported audio formats include .mp3, .aac, .ogg, .wma, .wav, .flac and .m4a.

The estimated size of the converted files will be shown, which is handy when trying to fit tracks onto smaller audio players.

Although the button is marked Audio it can be used to open video files to extract their audio. Video formats that can be converted include .avi, .mp4, .wmv, .dvd, .mpg, .3gp, .flv and .m4v.

It is also possible to select a different folder for the converted tracks saving the extra step of copying converted files to a device.

The join files slider at the top right will combine all of the loaded audio files into a single file.
