inline |
Creates a uniform waveform as a copy of a sparse one.
It is assumed that the sparse waveform is actually sampled at regular intervals (i.e. m_durations={1, 1, ...1} and m_offsets = {0, 1, 2... N} ). If this is not the case, sample data is copied verbatim but timestamps of the resulting waveform will be incorrect. No validation of timestamps are performed.
