The Standard algorithm is optimized for CPU-efficient realtime processing.

The following presets are available:

Standard – Drums

For percussive sounds. This mode does not change the timing of your audio. If you use it with certain tuned percussion instruments, you may experience audible artifacts. In this case, try Mix mode as an alternative.

Standard – Plucked

For audio with transients and a relatively stable spectral sound character like plucked instruments.

Standard – Pads

For pitched audio with slower rhythm and a stable spectral sound character. This minimizes sound artifacts, but the rhythmic accuracy is not preserved.

Standard – Vocals

For slower signals with transients and a prominent tonal character like vocals.

Standard – Mix

For pitched material with a less homogenous sound character. This mode preserves the rhythm and minimizes the artifacts.

Standard – Custom

Allows you to set the time-stretching parameters manually.

Standard – Solo

For monophonic material like solo woodwind/brass instruments or solo vocals, monophonic synths or string instruments that do not play harmonies. This mode preserves the timbre of the audio.

Custom Warp Settings

If you select the Standard – Custom mode, a dialog opens where you can manually adjust the parameters that govern the sound quality of the time stretching:

Grain Size

Allows you to determine the size of the grains in which the standard time-stretching algorithm splits the audio. Low grain size values lead to good results for material that has many transients.


This is the percentage of the whole grain that will overlap with other grains. Use higher values for material with a stable sound character.


This is a percentage of the whole length of the grains, and sets a variation in positioning, so that the overlapping area sounds smooth. A variance setting of 0 produces a sound akin to time stretching used in early samplers, whereas higher settings produce more rhythmic smearing effects but fewer audio artifacts.
