Disclosed is an apparatus and method for manufacturing SiO, which may lower a manufacturing cost of SiO by collecting SiO continuously. The anti-fog coating precursor is converted into an actual anti-fog coating by applying on the surface thereof a film of a liquid solution comprising at least one surfactant. The parameters for a frame of the audio data can identify best match blocks for time scaling or represent a plot of offset versus time scale that can be interpolated to determine an offset.
