Resampling/ Timestreching/
Pitchshifting
Note: If you only want to change the sample rate of an audio file, use the Adjust sample rate option from
the Effects Menu.
All algorithms in this dialog use the time factor parameter and pitch as input parameter.
The time factor calculation (from the original length/original speed and the length required / speed
required) can be comfortably activated on the right side of the dialog.
Resampling
Samplers and PCM Synthesizers transpose samples during this procedure. Time factor and pitch are
dependent upon each other: the shorter the audio material, the more higher the pitch. The effect is
comparable with changing the playing speed of record players or tape recorders.
The effect is relatively loss-free, the sound loss is smaller than with all Timestretching/Pitchshifting
procedures. If pitch change is justified by changing the speed (and vice versa), use this algorithm.
When lengthening the audio material by resampling, very small aliasing effects may occur. the anti-
aliasing filter helps in this regard. Alternatively, since this filter requires additional CPU load, it can be
activated for the computation and the real-time preview. The filter is also available for the other
algorithms that use resampling internally when pitchshifting.
Pitch-Shifting/Timestretching
With all other algorithms, pitch and length variation are independently adjustable. These algorithms
produce artefacts, and depending upon the audio material, other algorithms may produce better results.
The algorithm used for Timestretching/Pitchshifting as a default object effect can be stored in the wave
project with the Timestretch-Patcher.

An algorithm is used that usually produces very good results. It uses factors (from 0.9 to 1.1) and fixed
