Amazing Slow Downer is a Mac utility designed to help you alter the speed of your songs without changing their pitches. The program might prove to be of good use if you want to slow down a sound file to analyze it easier and more efficiently on your computer.

It might also come in handy if you recorded an audio file on your Mac and need to increase the speed of the resulting sound file before sharing it online.

The utility is packed with a user-friendly interface, features easy-to-configure output settings, and immediately completes any given tasks. What's more, you can import various types of data. Not only it supports a lot of audio formats as input, it also lets you import and alter music from audio CDs, the iTunes library, and the playlists within your Mac.

Only 2 aspects you need to take into consideration before buying this tool for your Mac: you can find cheaper solutions (they aren't as feature-rich as Amazing Slow Downer though) and the fact that it supports a limited amount of output formats.

However, you should give this utility a try if none of the aforementioned flaws mean anything to you. It brings you many useful features, offers you high-quality output files, and works 100%.
