Very capable
I am just trying and have bought this week. I use this to get mp3 files into the right key so I can practice playing and singing music alongside them. I expect I may use the slow down to practice and build up my speed on the guitar as it is totally incremental. The speed up is good to save time when I'm checking the format of songs when I'm writing chordsheets. I really hope that there is work done on making it more user friendly for folks like me and the interface easier to navigate. Haven't got my head around Batch Processing but hope it would do things like being able to save a bunch of files all together in one place rather than individually like I did yesterday just to get it done. Great piece of kit all in one place
