The Capture app records into C16 files, and the Replay app read those files.
As described in the [PortaPack Wiki](https://github.com/sharebrained/portapack-hackrf/issues/139) this format consist of a tuple of 16 bits signed integers. The first number is I and second Q, forming a complex number. As a result, you get a tridimensional representation of the capture: the real and the imaginary parts in the file (I and Q) versus the time (defined by the sample rate, in this case in an adjacent TXT file with the same filename as the C16).
