If you're a musician who likes to learn new songs and techniques by listening to the same piece of music over and over but wish that the music could be played a little slower, then you'll enjoy Amazing Slow Downer.
You can repeat any section of the music at full speed, slow it down or even speed it up by changing the speed between 25% (1/4 of original speed) and 200% (double speed) without changing the pitch!
Change the tuning or musical key? No problem, Amazing Slow Downer handles that as well.
Setup seamless loops by touching the "Set" buttons during playback.
Amazing Slow Downer is the ideal tool for any musician, transcriber or dancer wanting to improve their skills.
Cannot play DRM protected files from the iTunes store (m4p and audio book files).
New - Made it possible to start and stop playback in the "Trim Loops" view
Change - Workaround for a bug in iOS 12.2 that prevented playback after exporting a song
Bug fix - Minor fix related to reading ID3 tags in mp3 files
Ratings and Reviews
NYC Violin teacher here, uses frequently
I am violin teacher and I use and recommend this app a great deal. However, there is one thing I would really love if the developers would consider (which would make this a 5-star review) and that is a way to adjust speed percentages by + or - 1 with the tap of a +-1 button just like you can with moving forward or backward in seconds. I would also love love love if you could either modify the small movements back & fwd or have more options available to do so (e.g. 5, 10, 15 seconds.) It would also be out of this world if you could develop place markers or tabs for points of difficulty that you could just jump to go practice. E.g. One at 1:36, one at 2:30, one at 14:53, etc. (Also would be great for jumping to the next movement in classical music).
That being said I will continue to use this app and hammer on the << or >> 1 second button until this feature (hopefully) comes out. I haven't tried other similar apps (if they exist) but this one has been great to me, so am true blue all the way. Highly recommended. Get it.
More than worth the price!
More than worth the price! Truly a game changer! I tried cheaper options and their interface looked more interesting, but those looks were deceiving. Those others were difficult to effectively manage and really buggy. ASD proved to be “amazingly” intuitive, easy to organize what you’re learning, and completely bug free. You do have to “own” your iTunes music that is imported, and they have to be downloaded to your device—Apple won’t let you work in other programs with their music otherwise. I do pay for Apple Music, so I have to individually purchase those pieces I decide to accompany on my banjo. But that is a very small added cost for the time ASD saves when learning the song. Besides having quick and easy control of pitch and speed, the setting of focused sections of songs is very easy—I was setting focused loops on the fly the first night of practice using ASD. Each loop only took seconds to create and are automatically organized under a disc looking icon linked to the song. Having the loops organized with each song like that is one of the many details that make using ASD intuitive and effective. I do not typically leave reviews—less than a half dozen made in my lifetime across all platforms—so this review is a sign of how impressive and helpful this app truly is. Thanks for this great product!
Great for slowing down difficult percussion passages. Some distortion is present at very slow speeds, but it's still completely workable. Didn't read all other reviews, but if you come across a "protected" file that won't import - there's a way around that too.
Checking back in on this app in 2018. I’ve used it religiously for the past 6 1/2 years and it is STILL amazing. Someone complained that it was too expensive at $15 (a few years ago). Are you kidding me?? For the serious musician that works at getting things right, this app is priceless. Given the amount of use, time saved, and difficult passages learned - I would in retrospect have gladly paid $50 for this. Regular updates keep it working smoothly. I also dislike that it won’t import protected songs from iTunes (which I HAVE paid for). Not the app designer’s issue - it’s Apple’s. But you can simply burn the songs you want to slow down onto a CD as a regular mp3 file, then import that version into your ITunes and import it into ASD. It’s an extra step, but again, if you’re serious, it works and is worth it. THANK YOU, app designer - this has been a godsend!
With Family Sharing set up, up to six family members can use this app.
