same with Audacity  ‍      

Basically the same thing as Audacity, but mobile. It’s really great for on-the-go audio editing and I’m very happy with it. There are some features that I wish existed, but other than the few things it’s a great software. ‌     ​‍

Great App for Paste Mixing      ‌

Simply import sounds from files and the sound is excellent. I wish it had a more extensive sound library. Overall, quite excellent.   ​

Accessible, but needs improvement

Hi, I just played around with the app with VoiceOver, and it’s somewhat accessible, but needs improvement. The tabs on the bottom are not labled, and some of the buttons are labled weirdly. Please make the app 100% accessible for VOiceOver users.
