Buy Roni music Amazing Slow Downer
near Glendora (US) at: |





Loading...
Lives up to its name! I've listened to a lot of software for slowing down audio, and have even written some myself, but this is definitely among the very best in terms of sound quality. Given that you'll be listening
Apart from the excellent sound quality, here are some other good points:
- User interface doesn't look fancy, but it's certainly usable and flexible.
- Choice of slow down methods, from "Slow Down Type I" through "Slow Down Type V". A different method may give better results depending on the type of music (though so far, to my ears, "Type IV" sounds the best for all the music I've tried).
- Batch processing: you can add a bunch of files to a playlist, then save slower versions of all of them in one go.
- Allows you to save slowed down (and/or pitch shifted) versions to mp3/m4a/etc. which you can then copy to your iPod or other mp3 player. Very handy if you want to learn tunes while listening to high-quality slowed down versions without using your computer.
Some minor gripes:
- The unlocking process when you buy is a bit odd. You don't get a product key; instead you get another installer which installs some file(s) that convert the trial into a full version.
- To save output as mp3, you need to separately download and install the LAME encoder (even though there's already a QuickTime mp3 encoder on the Mac).
- Saved slowed-down versions have the same file names as the originals, but don't preserve any of the tags (Artist, Album, etc.) of the originals. So if I save a slowed version of Eric Johnson's "Cliffs of Dover", and add the saved version to iTunes, it won't appear when I search for "Eric Johnson".
All pretty minor gripes. Overall, for the price, this is a remarkably good tool - especially given the excellent sound quality.
