Great, with help

A recent update took away functionality. Happily, the developer is able to help, returning the app to being very useful.

Excellent utility

Having stumbled through this with little or no help, guides or videos etc, I now can’t understand the distinct lack of awareness of this utility. There’s nothing on Google, YouPube videos or anything about this outside of the App itself - however; this has the most incredible algorithm of any similar utility I’ve ever used; it’s quite remarkable just how much you can alter the speed or pitch whilst retaining the original audio fidelity - then exporting files or selected areas makes it an invaluable resource for finding progressions as both single-notes and backing chords, and it also detects chords outside of the standard chromatic scale. It’s awesome, it should be brought to the attention of every musician or keen student!

Stopped working

It worked great for a couple of months. One day it stopped extracting songs. It works on random videos that I don’t want, but if it’s a track off an album or a single, it doesn’t work at all. Very frustrating as I used to use it to make music and play along to.
