Note (*) : Currently , **for correct Replay application ,you should ONLY use Capture App selecting any Bandwith capture <= 600 Khz. (500Khz recommended for majority micro SD cards compatibility)**. 600khz may need fast and good quality micro SD Card , and with not so high random latency . (In the GUI , those correct bandwidth capture options appear with the Normal usual "REC" icon Background colour, as user recomended BW capture options)
Above 600Khz bandwith options (with YELLOW REC button background Icon), in current fw version , the recorded files are “decimated” , and it has not recorded all full original samples content and therefore it is NOT useful for the Replay App , just useful to check the spectrum image, example using the tool "inspectrum" ). Anyway when replaying those captured files , the replay time will be shorter than real . but normally you should always got modulation.
In future versions, it is pending to investigate and try to apply a correct .C16 recording files (without any decimated samples ) till a capture of 1Mhz.

Anyway when replaying those captured files , the replay time will be shorter than real . but normally you should still got modulation, but in case of voice contents, it would sound ,not natural , "like with accelerated playing speed" , because in fact,due to Hackrf One System limitations,those recorded files (under BW with YELLOW icon) has decimated contents - with some skipped samples.
In future versions, it is pending to investigate and try to apply a correct .C16 recording files (without any decimated samples ) till a capture of 1Mhz. (We will keep updated that manual , when we achieve it)
