I have only fooled around with my voice so far but I can see a use for in making certain types of emotional appeal. The reason for three stars is that there is a constant pumping sound in the background weeohweeohweeoh........, and a sound like ocean waves or hf radio atmospherics.., that doesn’t seem related to the mic picking up breathing or heartbeat, it appears to be an artifact of the processor, it continues with no obvious input. If you decrease all controls to below 50% it begins to go away.I intend to bring to the attention the developer. You could not use this app for production the way it is. Edit: I have reduced my rating to 2 stars because the developer does not even show Alien Box on the Biala home page. I have addressed the artifact problem in an email, and if I get a reply I will revise my review accordingly.Edit: I have received a developer reply. The app is not his website because it is not selling as well as others. The pumping is an inevitable result of the processing. He apparently does not intend to do anything about it. If you can stand an app that sounds like it’s being broadcast from Pitcairn Island on HF radio, go for it. It’ just interesting enough to keep two stars for me, but it can’t be used in a real production because of the obvious noise.
