respeed

y = respeed ( x,factor )
y = x.respeed ( factor )
y = x ~ factor

Resample the sound (and keep the sample rate); equivalent to a playback of the audio at a higher/lower speed in a tape player.

Description

Unit or Value scale

x

AUD

Audio signal


factor

SCL or TSQ

The factor to increase the speed of the playback


Outputs

  • y is AUD or VCT

Notes

  • This changes the number of samples in an audio signal. Internally, the signal is treated as if it was resampled. Note that this does not mean the change of sampling rate in the AUXLAB environment.
  • The audio compresses in time by the factor of x and its spectrum expands by the factor of x.
  • Similiar to pitchscale, but the duration changes in respeed
