    I was looking for a lightweight Pink Noise generator... downloaded several to try, and WISH this one won. It has a clean, simple interface, great adjustability, and seems stable. If it played in the background, and appeared in the notification bar, it would be IDEAL. It's a great app for testing speakers, but thats about the only application I can think of...

    This is a sweet little app but could use 2 things: 1) A background mode (I need to run an analyzer on my phone while the generator is running) and 2) A sweep function! In any case, great work and thank you for sharing with us!

    For some reason this app turns your phone media volume up to 100% regardless of setting and leaves it up after. I've been deafened a couple of times when I go to listen to music after.
