Adaptive Differential Pulse Code modulation (ADPCM).<\/p>\n<p>ADPCM is a lossy compression algorithm that encodes the difference between two consecutive samples of an audio signal. This is done by using a predictor to estimate the next sample value, and then encoding the difference between the actual sample value and the predicted value.<\/p>\n<p>ADPCM is a very efficient compression algorithm, and it is often used in applications such as voice compression and music compression.<\/p>\n<p>The other options are incorrect for the following reasons:<\/p>\n<ul>\n<li>Silence Compression is a technique that is used to remove silence from audio recordings. It does not encode the difference between two consecutive samples.<\/li>\n<li>Linear Predictive Coding (LPC) is a technique that is used to model the spectral envelope of an audio signal.
