The varispeed effect occurs when the playback speed of a tape machine is altered, causing both the pitch and the duration of the audio to change simultaneously. In a modern DAW, this is achieved by bypassing modern 'time-correction' algorithms and using 'Resampling' or 'Tape' modes that mimic physical motor speed changes.
- 1.Switch your DAW's time-stretching algorithm from 'Elastic/Pro' to 'Tape' or 'Resampling' mode so that pitch and time are linked.
- 2.Use a pitch-shifting plugin like Soundtoys Little AlterBoy or Waves Abbey Road J37 set specifically to 'Varispeed' mode.
- 3.Automate the Master Pitch or Project Sample Rate (if your DAW allows) to create the classic 'wind-up' or 'slow-down' effect during transitions.
- ×Ensure your DAW isn't 'correcting' the pitch automatically, which will result in digital artifacts rather than a smooth tape glide.
- ×Realize that changing speed will move your audio off the project grid; you may need to manually realign clips after processing.
- ×Extreme varispeed shifts can cause aliasing in lower-quality plugins; always use high-quality resampling modes.
If your DAW doesn't have a dedicated 'Tape' mouse tool, use the Pitch Bend automation on your sampler or a pitch-shifter plugin set to 'linked' or 'resample' mode to ensure the timing scales with the pitch.
