U-law
U-law is a lossy method of audio encoding that will compress 16-bit linear PCM audio samples into 8-bit samples thereby reducing bitrate by 50%. Like its encoding cousin, a-law, u-law assumes that the audio stream contains predominantly voice data (as opposed to, say, music data) which has a low dynamic range. It then uses a pseudo-logarithmic algorithm to compress the data, favoring detail for samples in the “middle” of the range and effectively glossing over samples at the extremes.   Read more...See also: Audio
