Accessible through the “Signal tools/Resample” menu option or the toolbar button.
Resampling is the process of changing the sampling rate of an existing signal. A new signal should keep all information contained in the original signal.
A resampling dialog in SIGVIEW lets you choose a new sampling rate for the signal and shows you a resampling factor (a ratio between the new and old sampling rates). This factor must be in the range [0.1, 10], i.e. you can increase (up-sampling) or decrease (down-sampling) the sampling rate by the factor of 10.
For some combinations of the current and new sampling rates, SIGVIEW will not be able to precisely achieve the requested new sampling rate. For example, when converting 44.1 kHz signals to 48 kHz signals, SIGVIEW will generate a signal with the sampling rate of 48000.00114 Hz. This is caused by the underlying algorithm.
As with all SIGVIEW functions, resampling is performed only on the visible part of the origin signal. Any change in the origin signal, for example zooming in/out will cause the resampled signal to be recalculated.
