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 Lite.

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 Lite handles that as well.

Setup seamless loops by touching the "Set" buttons during playback.

Amazing Slow Downer Lite is the ideal tool for any musician, transcriber or dancer wanting to improve their skills.

Supports playback of streaming audio from "Apple Music" and "Spotify Premium"!
Some functions such as "Pitch change" and "Equalizer" are not available when playing "Apple Music" songs.

Important notes:
This free "Lite" version is restricted to play the first quarter of an audio file.

A great piece of kit

I was a bit apprehensive loading songs using wifi and also about spending £8.99 on the full version. But downloading is really easy and the programme is uncomplicated and works well.
It would be nice to be able to download a complete folder of mp3s in one go but apart from that its excellent.
I shall have no hesitation in buying the full application

Great app

Having been a longtime fan of the desktop app (which is quite expensive), I was pleased to see this version. Being able to adjust it by touch rather than using the mouse is great when playing along.

There seems to be very little loss of sound quality when adjusting speed, mix and pitch.

In a world of free apps I’m sure some people will think this is pricey but it’s good quality and well worth the money.

Seems to work perfectly

Sliders control the speed and the pitch, so you can slow down a track to work out tricky sections, or transpose a track if it's in the wrong key. Other sliders control start point and end point so you can work on section of a track.

This is the free version, so only appears to import 1 minute of a track, and other functions are unavailable, but I'm definitely convinced that the app works well. £10 might seem a bit pricy, but if you've got to learn a lot of songs for a paid gig, the time saving will quickly make it worth while.
