I am developing a music education application and require a developer or team of developers.
CHALLENGE: The application must record video and audio WHILE playing back video/audio. Our users must be able to record themselves while listening (via headphones) another collaborator's music. It can and has been done! There is an application on the Apple app store called Acapella that uses this funcationality. But most developers agree this is a challenging task and don't know how to do it. Do you? If you know how to do this I want to hire you as soon as possible.
Please research the Acapella by Mixcord app to see if the record video while playing video functionality is something you can recreate. If so, I want to hire you!
This app must work on iOS. It must also work on either Android or Desktop.
