A command available in the Query submenu if you select a Sound object. The Info window will show an estimate of the amplitude (sound pressure in Pascal) at a specified time. If that time is outside the samples of the Sound, the result is equal to the value of the nearest sample; otherwise, the result is an interpolated value.

Settings

Time (s)

the time at which the value is to be evaluated.

Interpolation

the interpolation method, see vector value interpolation. The standard is “sinc70” because a Sound object is normally a sampled band-limited signal, which can be seen as a sum of sinc functions.
