Input devices of the audio studio that formerly were physical have mostly been converted into virtual controls on the computer screen. Whereas this transition saves space and cost, it has reduced the performance of these controls, as virtual controls adjusted using the computer mouse do not exhibit the accuracy and accessibility of their physical counterparts. Previous studies show that interaction with scrollable timelines can be enhanced by an intelligent interpretation of the mouse movement. We apply similar techniques to virtual faders as used for audio control, leveraging such approaches as controllable zoom levels and pseudo-haptic interaction. Tests conducted on five such methods provide insight into how to decouple the fader from the mouse movement to improve accuracy without impairing the speed of the interaction.
