Thank you for many posting for our project. By discussion by our executives, we're very sorry to change our requirements a little bit


*Player - Design distributed parameter by XML (need to be encrypted and digital-signed)

*Other - We have vocal reduce engine using STFT by a standard math library. But for future release, we need to have android version of it. Mandatory have skill to convert the Engine.

*4 times Design Executive's Review - around every 1-3 weeks, we'd like to have times to review design overall by our executives. So we requests to you to write reports (in English is OK) for each review and a program which is workable on our iPhones at the time. (Possible using TestFlight or some CI tools, but need to easy step how to document) (Aug 26, 2013)
