Great program for EVPs. However, after one use, you can't save to an MP3 format until you pay for service. NOT FREE! Be warned.You can't advertise or Google search something that is supposedly free if it truly isn't. Shady!
Simple and easy. Free Audio/Sound editor not worth Sound Forge or Reaper but do lot of thing for nothing. Thus for small sound smithy but definitely not musician because you have to search in menu.
