Switch is just as useful for professionals that need to convert many songs into multiple formats as it is for the average person who knows they want to convert an AAC file to MP3. Switch is able to handle many different audio formats and has the largest selection of output formats of any program we reviewed. This makes it useful for many different situations and music players.

Overall, Switch really impressed us with its features, compatibility and price. And to top it all off, NCH Swift Sound also sells several add-on programs that can expand usability. With top marks in every category, Switch definitely gives you the most functionality for your money.
