A command that becomes available in the Query menu if you select a sound-analysis object that is a function of time and that is evenly sampled in time (Pitch, Formant, Intensity, Harmonicity).
The Info window will tell you the time associated with the frame number that you specify.
the result is
|t1 + (frame_number - 1) · Δt|
where t1 is the time associated with the centre of the first frame, and Δt is the time step.
If you select one of the above objects and click Inspect, you can see how the relation between frame numbers and times is stored in the object: t1 is the x1 attribute, and Δt is the dx attribute.
