I am working a little on some acoustic monitoring using smartphones. In respect to that I was pondering whether it is possible to write an iPhone app in e.g. swift for iOS that is capable of transmitting an audio file to either a MATLAB desktop computer or MATLAB software installed on a server and then have MATLAB evaluate the audio file prior to sending the result back to the Phone. Here the catch is that I would like to avoid e.g. the MATLAB mobile interface in order to be able to customize the user interface. Would such a task perhaps only be possible by deploying MATLAB code on a MATLAB Production Server or is there perhaps a general software architecture problem in interfacing a custom build smartphone app with MATLAB?
