For a media item (specifically audio), the descriptor essenceTrackSamplingRate measures How Often data is sampled when information is digitized. For a digital audio signal, the sampling rate is measured in kilohertz and is an indicator of the perceived playback quality of the media item (the higher the sampling rate, the greater the fidelity).
