In any instrument it is possible to replay the data in real-time, faster or slower. Therefore Dewesoft offers special control buttons: Start/Stop, Sound output selection, Replay mode for selection different ways of replay, Replay direction and Replay speed in different Display Screens, which you can find at the top right part of the window:

Dewesoft will immediately start to move through the acquired data: the FFT is calculated, scope shows the current data, the video file is replayed, digital or analog meters, bar graphs,… will change their value continuously and in recorders or scopes you will see the yellow cursor moving to indicate the current position within the file.
